1, how to charge the battery for a new

The use of lithium batteries should be noted that after some time the battery is placed into hibernation, lower than normal capacity at this time, the use of time has also come to shorten. However, lithium batteries can easily activated, as after 3-5 times the normal charge-discharge cycles the Laptop battery can be activated to restore normal capacity. As the characteristics of lithium, its decision is almost no memory effect. The lithium battery so that the new user during the activation process does not require methods and special equipment. Not only is the theory that, from my point of view practice from the start on using the standard method of charging that “activation” is the best approach.

For the lithium battery “activate” problem, many say, is the cooldown should be longer than 12 hours, three times in order to activate the battery. This “The first three load over 12 hours to charge” was obviously the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that the beginning a miscommunication. Lithium batteries and charge the battery nickel and discharge characteristics are very different but also very clear to you that I have gone through all the serious official stressed that the technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion causing major damage. According to the standard load and therefore the best time and the standard method of pricing, in particular, do not make more than 12 hours of ultra-long burden.

In addition, lithium batteries or charger stops automatically when the IBM 40Y6799 battery is fully charged, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white horse is also sufficient. And we can not guarantee that no one battery charge and the circuit characteristics of discharge protection and will never change and the quality of the safety device so that your battery will be of long duration space flight hazard. There is also another charge against the main reason.

In addition, in some machines, charging more for some time, if they do not remove the charger, this time not only to stop charging system will start to discharge – charge cycle. Perhaps the makers of this approach have its own purpose, it is clear that in terms of battery life is a drawback. At the same time, charging time would take some time, often at night, but our situation to the electricity grid at night in many places, over voltage, but also volatile. As already said, the lithium batteries is very precious, and more than nickel in the electric charge and discharge aspects of fluctuations in the resistance is much less, if this brings additional risk.

In addition, another aspect can not be overlooked is the lithium Dell Inspiron 9300 battery is not appropriate for excessive discharge, excessive discharge of lithium batteries is also very unfavorable. This leads to the following questions.

2, normal use should be time to start charging

As the number of charging and discharging is limited, must be used as possible, recharge the electric battery. But I found one on the charge of lithium-ion battery and Table discharge cycle test, data life cycle is as follows:

Cycle (lifetime 10% DOD) :> 1000 times

Cycle (lifetime 100% DOD) :> 200 times

DOD is the depth of discharge whose English acronym. Can be seen from the table in May of depth charge and discharge times, 10% DOD cycle life when the DOD of 100% for much longer. Of course, if the equivalent of actual costs to the total capacity on 10% * 1000 = 100100 * 200% = 200, one full charge and discharge, or better than some, but not before friends say some changes: Under the normal case, you should have a standby hp Pavilion dv6 battery power is left in accordance with the principle of charging the short load again, but if your battery in your first two days can be expected to persist throughout the day, when they should start on time charge, of course, if you’re willing to back the charger to the office again a different issue.

And you need to recharge in order to cope with the communication provided lead busy to come to an important event, even if a lot of battery power over time, then you just charge ahead, because you don ‘are not really lost, “as a” life cycle support is “0.x” times only, and that x is often very low.

Short on battery and then filling the rest of this principle is that you want to go to the extreme. And long as charging a widespread view that “as far as possible from the machine run out of battery, it is preferable to use automatic shutdown.” It’s really just practice for nickel, the goal is to to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It was because the machine is too low sony VGP-BPS2 battery warning appears, still do not charge to continue using the example has been used in automatic shutdown. The results of this case, the machine later in the pricing and first there was no response, had to review services to clients. In fact, because of the battery caused by excessive discharges of electricity at low voltage, so that was not the normal load and footwear and conditions.

3, the correct way for lithium batteries

To summarize, the use of lithium batteries for loading and unloading, the most important recommendations are:

a, in accordance with the standards and procedures, charging time, even the first three have to do;

b, when there is low power consumption machine when prompted, should try to start charging a timely manner;

c. lithium batteries do not need to activate a special mode in normal use, the machine will naturally activated in lithium batteries. If you insist on spreading the use of “three previous 12-hour long activation charge” approach, in fact, there will be no effect.

Therefore, the pursuit of all super-long 12-hour rechargeable lithium batteries used and the integration of the practice of automatic shutdown are wrong. If you’ve already done under the argument wrong, please correct time, perhaps not too late.

4, the use of lithium fire

Some people may experience from mobile phones began to lithium batteries. In fact, it is used in household appliances. Needless to say that the lithium apple A1061 battery efficient, lightweight, and if its benefits are open to promote the use of quickly. But, you know, wasting, it will cause you to “fire” of the upper body?

Lithium batteries have a light body, high efficiency, low temperature (-40 ℃), etc., 0.3 mm thick buffer size lithium battery can be used continuously for more than five years in recent years are being phased out are used in batteries and alkaline manganese batteries, widely used in many high-end devices for home and mobile handsets.

Unlike lithium batteries are used in batteries and alkaline manganese dry zinc chloride and aqueous potassium hydroxide electrolyte, which use an organic solvent. Lithium use cathode of manganese dioxide, lead fluoride, thionyl chloride and other materials. Anode used in the anode of lithium metal foil with the general use batteries of zinc chloride versus the ionisation tendency of strong difference, positive and negative high voltage, so that the improvement work effectiveness of lithium batteries.

However, lithium batteries are often in the course of fever, burning phenomenon, the impact of light by the host to be used in severe cases will also cause a fire burned the host. It is reported that Japan has in recent years there have been several cases of Li-ion battery heat caused by the family fires burning.

Why lithium batteries fever and burning? Most materials original lithium battery in contact with water, after severe chemical reaction can occur, releasing a huge amount of heat leading to fever, the phenomenon of burning. Manganese dioxide lithium battery cathode, only a small drip can dive phenomenon of fever. Lithium-thionyl chloride in contact with water in the production of hydrochloric acid and sulfur dioxide, while the heat, several factors make life lithium batteries to become the “go” and So people are using lithium batteries should pay attention to water-proof, anti – wet. A variety of home disabled, they should remove the batteries placed in a dry, cool to care, to prevent and avoid inappropriate use of lithium battery fires caused by household accidents.

1 Industry of lithium carbonate status quo

According to Sheng-mao, the global lithium carbonate industry, the status quo, the threshold of significant resources, capacity is highly concentrated. At the end of 2007, global demand for lithium carbonate for a total of about 93,000 tons, major international manufacturers have SQM in Chile, the United States and Germany, FMC Chemtall Total annual capacity of 78,000 tons, representing 80% of global market share. The large-scale production of lithium carbonate as the company needs to have reserves of lithium Laptop battery resources are more abundant in salt lake resources, mineral rights, which makes the resources of industry with higher barriers to the entry, on the other hand, the vast majority of the planet’s resources are at high salt magnesium low base of lithium, and high-Mg low separation of brine lithium carbonate lithium technology process purification is very difficult to control before such technology is only a few hands of foreign companies, making the industry of lithium carbonate, but also provides many technical obstacles. Therefore, lithium carbonate has created the oligopoly structure of global industry.

Lithium Salt Lake in the independent R & D, which provides technology and production process of magnesium on the basis of a number of large industrial enterprises in China in recent years in the depths of the Qaidam Basin Zabuye Salt Lake and start build lithium carbonate, magnesium hydroxide and other chemicals production base. The current national production of lithium carbonate businesses mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the extraction of Tibet and CITIC Guoan has accounted for the vast majority, the two companies in 2008, lithium carbonate Total production over 4000 tons.

Statistics show that the hinterland of Qinghai-Tibet Plateau is located in the Qaidam Basin, rich in potassium, sodium, magnesium, IBM ThinkPad T40 battery, boron and other mineral resources, including magnesium chloride 3 , 1 billion tons, representing about 99% of the country to maintain reserves, lithium chloride nearly 14 million tonnes, representing 83% of countries maintain reserves. In early 2007, human West taijnar Qinghai CITIC Guoan Technology Development Corporation-Project tons of lithium carbonate officially put into production in the Qaidam Basin, the taijnar West Lake has become an important production base for lithium carbonate.

2 Industry of lithium carbonate bottlenecks

Currently, the world production capacity of lithium carbonate is still low production costs are high, not really large-scale mining, the company is always looking for the most economical mode and reasonableness of the production, currently hinder the development of industry lithium carbonate is still the biggest problem is the technology of production process. In the short term, Tibet, mining and technology in the production of CITIC Guoan is still insufficient, the annual production is only 2,000 tons, respectively, representing a lower percentage of average principal activity is difficult to drive performance has increased considerably.

Chinese Academy of Sciences, said Li Jian, researcher, Salt Lake extracting hp Pavilion dv6000 battery, magnesium technology, to mention a bottleneck “and gradually made inroads in industrial production shows that China has Salt Lake Independent Human Rights IP development of overall use of resources based on the overall development of salt lake resources, access to large scale production of lithium, magnesium, a new phase.

3 production of lithium carbonate internal business analysis

(1). CITIC Guoan:

Qinghai CITIC Guoan currently holds 99.375% interest in national security. Qinghai national security was created in 2003, mainly engaged in Qinghai Salt Lake, West taijnar lithium, potassium, boron, magnesium and other resources for development overall. West taijnar Salt Lake Qaidam Basin is located in the middle of an area of 570 square kilometers, the liquidity necessary to reserve of 3.08 million tons of lithium sony VGP-BPS5 battery chloride, potassium chloride 26.56 million tonnes, 1, 63 million tons of boron oxide, magnesium chloride 185.97 million tonnes. Calculated based design capabilities, these resources available to the company for at least 25 years of operation, the potential economic value of 170 billion yuan.

(2). Tibet Mining:

CITIC Guoan has lithium-magnesium associated minerals, the two or three years has not been a breakthrough in technology, mining in Tibet dominant position on raw material inputs is highlighted quite. The company now has reserves of lithium in the first in the country, the third largest mineral rights Zabuye Salt Lake for 20 years. That the world exists in the form of lithium carbonate in natural salt lakes, in addition to the natural background of the lake shore and deposits of lithium carbonate, the water content of lithium carbonate in a conservative estimate as high as 200 million tonnes. The Mg-Li ratio was only 0.02, the anomaly of a high proportion of Mg-Li problems brine lithium, so in future benefit from the extraction of Tibet has great potential.

(3). Western Mining Group

Qinghai Western Mining Group currently controls 74% of the lithium toshiba PA3421U-1BRS battery industry shares. Qinghai Lithium Co., Ltd is currently taijnar, to meet the capital of Qinghai Salt Lake lithium extraction and use of resources demonstration projects of industrialization. In October 2007, Western Mining Corporation rated capacity of 3,000 tons of lithium carbonate project started for production. After a year of operation and transformation of production processes and optimization, in September 2008 reached lithium carbonate capacity on the project to achieve at the current production of products of lithium carbonate for more than 1,000 tons or more than 99.5% product quality and achieve low-cost, non – high temperatures and corrosion, no gas, cleaner emissions, no residues of the large scale production.

(4). Salt Lake Group:

In view of the overall use of Salt Lake magnesium, lithium and other resources, “Eleventh Five-year period” in Salt Lake Industry Group will invest an annual production of 100,000 tons of magnesium chloride anhydrous, 10.000 tons of carbonate lithium apple A1061 battery and so on, to build modern high-tech base in the salt industry. Salt Lake Group, a subsidiary of LandTek lithium industry, its processes, including adsorption resin, elution, concentration, separation membrane and the process of carbonization. Years ago, installed in the front part of the adsorption resin debugging. lithium concentrations were lower due to brine a large number of brine into the resin bed, resin adsorption main problem is water consumption, consumption of resin and energy consumption, large, and because a substantial change in the adaptability of temperature enough resin, also addresses issues such as resin, broke in. It is estimated that the average production of 1 tonne need of lithium carbonate to consume about 600 tons of fresh water, the level of average consumption of renewable pH of about 5% of resin consumption is about 5% each. The cost of producing the need for further observation, expects its cost of 1.5 million tonnes yuan.

4, the industry outlook lithium carbonate

Li Sheng-mao said, the trend of development, new energy cars is without doubt the future development of the automobile, while the lithium battery electric vehicle is the best choice. The future market for lithium batteries and battery raw materials, demand is huge. For this reason, lithium carbonate, once the mining technology is a breakthrough; cost reduction to achieve efficient production scale industrial prospects for the future will be very broad.

According to the Investment Advisor “issued by the new energy vehicles in China during the 2008-2010 Industry Analysis and Investment Consulting Report, noted that by 2012, China had 10% of the Production cars are energy saving and new energy vehicles, according to an annual production of cars will be cars for the 10 million counted, the new energy vehicles in China to achieve an annual production of 1 million scale. Every new motor vehicle is expected to need about 0.08 tonnes of lithium carbonate, lithium batteries, once the engine of large scale application of new energy vehicles, the market potential of lithium carbonate be very large, the energy sources it is expected that 2012 cars on the annual demand for lithium carbonate will reach 5 million tons.

The current domestic price of industrial grade lithium carbonate to 45,000 yuan / ton or more, Dell Inspiron 1525 battery grade lithium carbonate price of 70,000 yuan / ton or so, the high purity lithium carbonate price is so high that 100,000 yuan / tonne or more, involved in new national projects, as it is extracted using salt brine lithium carbonate production costs in 10000-15000 yuan / tons. Therefore, the market generally felt that the profitability of products of lithium carbonate is very high, will give investors a huge increase.
