SH002 is also a charger, it also equipped with a reception at single band, FeliCa e-billing capabilities, the GPS receiver and Bluetooth transceiver functions such as high-end mobile phones in Japan, all features function of “full” model. And also has a resistance level IPX5/IPX7 water. Produced with the assistance of technical personnel has been dismantling.

Anti-noise solar battery module

First, look at the screen with a parts of the solar battery module. Sharp is equipped with solar A1008 battery module development. Dimension of about 67.5mm x 41.0mm x 0.8mm. To achieve the thickness of 0.8mm, using the technology of semiconductor packaging. “Whether domestic large-scale solar battery module thin. Tectonics completely different” (technical staff, a Japanese manufacturer of solar battery).

According to Sharp this conversion efficiency of solar battery modules is 13%, the maximum output power of 300mW Note 1). The output voltage of 4.5V, the voltage can be used for lithium-ion batteries. “10 The output voltage of 0.5 V solar battery polycrystalline silicon serial (the technical staff above). Module grounding has 9 dorsal electrode. Assisting in the dismantling of Japanese manufacturers of mobile phones and technical staff to speculate: “module of solar batteries may play a role in the antenna can easily generate electromagnetic noise. Thus, to take an anti-noise measurements. “

Shows part of the chassis is equipped with features of low power consumption of 1.1-inch monochrome e-paper. Solar battery module can display the feeding process with the performance when loading and free talk time. E-paper with a bright side to sensors, from the values obtained in the module’s electronic paper display in the use of solar BATCL50L batteries in the process of charging efficiency.

SH002 The main emphasis on two motherboards to PCB. RF circuits, digital circuits, signal processing, etc. Almost all major components encapsulated in the side of the motherboard. Vice-package-board, single module single band tuner and FeliCa with sending and receiving circuit. Components on the motherboard, such as RF circuits, power circuits and circuits for digital signal processing and so uniform. “It is very common in models of high-end Japanese components configured” (The Japanese manufacturers of mobile phones and technical staff).

The motherboard for mobile phone chips Qualcomm “MSM7500. It is the use of a high-pass and KDDI mobile phone to develop a common platform ‘KCP +’ standard chips, but also integrated into the GPS transceiver circuit. Sharp models from the summer of 2008 “W62SH” has begun to support KCP + terminals. Telephone main circuit follows the design of the original models, but their main efforts on the packaging of solar VGP-BPS2A battery modules.

Various methods of sealing the upper and lower casing

Equipped with solar battery modules, in addition, SH002 Another important feature is resistance to water IPX5/IPX7-level. The upper and lower waterproof case to achieve in different ways. Shows part of the chassis used is to use double sided tape on a frame with LCD panels and solar battery module sheet structure mask.

The keyboard side of the chassis used in both chassis and battery cases, respectively, between the folder structure in the filling of waterproof rubber for resistance to water. The side of the keyboard chassis material is fiberglass reinforced nylon resin off. In both upper and lower case are two ways of seeing “is also waterproof handheld products to achieve a very common approach” (The Japanese manufacturers of mobile phones and technical staff).

Improving the robustness of the measures is also equipped with rechargeable batteries can be seen. SH002 is equipped with lithium-ion rechargeable battery electrode is used in the shrink wrap on the motherboard to connect the terminal building. Japanese mobile phone rechargeable batteries typically radiate a flat electrode. The Sharp by changing the electrode structure so that when the phone slipped under circumstances such as poor contact of the battery has been defused. This electrode structure, Finnish Nokia and other handset manufacturers have adopted from abroad through the national mobile phone in Japan is also very rare “(technical staff above).

And many people do not realize is that the family of waste generated in daily life nickel-cadmium batteries and cell mercuric oxide and electronic waste, etc., of June 6, 2008 for more inclusive in the national list of hazardous waste “of.

An industry source in recent years the state to solve the pollution problem of used batteries, and make the source of cells for “mercury free”. Nine ministries and commissions under the December 31, 1997 jointly published a “product of the limited hp 338794-001 battery on the mercury rule” requiring that companies since January 1, 2002, the ban on domestic production of mercury batteries is higher 0.025% by weight of the battery, self – January 1, 2006, the ban on domestic distribution of mercury is greater than the weight of the battery of 0.0001% of the alkaline zinc-manganese batteries. Under current conditions of treatment are not very good conditions, a focus on environmental risks.

Tian Guirong also heard this news, she said, protecting the environment, the battery is not a problem, but in some places in southern Henan, which flows into the battery, only a few cents of each section so that the battery that can guarantee its security. Moreover, even if the IBM ThinkPad R50 battery is environmentally friendly, it is the whole body is a treasure, copper, zinc, leather, lead, recycling cans and garbage on the same cast in vain, that is not damage?

Background

Lead-acid battery is the most dangerous

According to the department of environmental protection-ie, the state offers three types of batteries must be recycled hazardous waste, namely lead from car battery acid car batteries, electric – button batteries and nickel-old cell phone, cadmium batteries.

According to experts, car battery, batteries for electric vehicles, lead acid batteries contain lead and sulfuric acid because it is the garbage dump, one of the most dangerous.

The data show that the lead acid battery electric bicycle is consumables, branded batteries for a year to be replaced two years.

“Aucma electric car service maintenance sales, trade toshiba PA3191U-3BRS battery in 330 yuan, if the direct purchase, it is necessary to 490 yuan.” Just here for the very fact that the batteries of electric vehicles, said, maintenance staff, said the batteries must be Depot, Depot Lane, following the lead acid battery to create a new battery.

The reporter again visited Zhengzhou several store brand repair, maintenance staff and the fact that the situation say about.

However, according to an informed source language, there are many streams of battery electric vehicles to the lifeboat station, where they are drained acid batteries in the position, then remove thecbattery inside the metal lead sale. Has been emptied of acid inside containing zinc, manganese, cadmium and other heavy metals, which contain harmful heavy metals, acid directly into sewers, then infiltrated into the groundwater, the consequences are frightening .

Proposed

As soon as possible to establish a comprehensive network of recycling

Some media reports, the expert of recycling waste in the use of renewable resources in Jiangsu Whampoa Limited, Chairman of the cursor Chen said that at present most domestic firms lack the capacity deal effectively with lead acid batteries can be discarded as garbage. While the electric bicycle is in use produces no pollution from exhaust gases, but the batteries that pollution caused by automobile exhaust is not much smaller.

The Tian Guirong, the lack of recovery of the apple A1008 battery capacity, not because no technology is the key to profit is too low, no one is willing to do.

According to its introduction in developed countries, approximately 50% of used batteries must be recycled through the creation of new social values. As the treatment of battery recycling industry protecting the environment, many national governments have to have subsidies, as in Switzerland and Japan, each dealing with a ton of waste batteries, a grant from corporate governance of waste battery, about RMB 5000. In the United States, if the user is not used to return the battery manufacturers, retailers or wholesalers, each bought a new battery will need to pay 3-5 dollars. Therefore, the United States, nearly 100% recovery of batteries.

China’s current policy of fighting against pollution featuring “polluter pays”, the call Guirong Tian: China should increase the variety of efforts to recycle batteries rectification and regulation of the market as soon as possible to establish a network Complete Recycling.
