BEIJING, June 4 /PRNewswire-Asia/ -- Himfr.com, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, reports that power battery products are facing problems.
Battery safety is not guaranteed. Currently, small- and medium-capacity lithium-ion battery industrialization has been very successful, but high-capacity, high-power lithium-ion battery safety problems have not been effectively resolved. While the battery capacity is larger, once out of control, there are greater dangers and risks.
Battery capacity is limited. Today on the market, the electric car's driving range is usually 100km ~ 300km after recharging, and this is only at moderate speed and with a good battery; the majority of electric vehicles can only travel 50km ~ 100km under normal circumstances.
Battery life cycle is short. Ordinary batteries can only be charged and recharged 300 to 400 times; or 700 ~ 900 times under optimal circumstances. It is expected that a battery will last four years at most, a short time compared with the vehicle's life cycle.
Battery quality and size are also problems. The existing electric vehicle battery cannot store enough energy while still being a reasonable size.
Batteries are expensive. Batteries for electric vehicles cost 100 U.S. dollars / kwh, some even as high as 350 U.S. dollars / kwh; the cost is too high, and consumers find this hard to accept.
Environmental pollution is a serious problem. Commonly used power batteries currently include lead-acid power batteries, nickel metal hydride batteries, and nickel cadmium batteries. Raw materials, from mining to production, then to waste processing, all pollute the environment.
Overall, the prospects for power battery development are promising, but the market is still new. Moreover, the power battery (http://www.himfr.com/list-product-Energy-10000000-1.html ) business is becoming bigger and stronger, leading to the need for a greater industrial scale, large-scale R & D investment. There is still much room for development.
