Zinc empty electric bus means the birth of the third route

On the issue of new energy technology routes, taking the route of pure electric bus or hybrid bus has always been a disputed issue. Recently, pure zinc-air battery electric buses have also come out.

Recently, as the only manufacturer currently qualified for the production of zinc-air battery passenger cars, the Dongfeng Yangzijiang Automobile (Wuhan) Co., Ltd. Passenger Vehicle Engineering Research Institute and Hubei Wuhan Wuhan Haoyuan New Energy Technology Co., Ltd. developed this new product. s concern.

Zinc air cells rely on the reaction of metallic zinc with air under the action of special electrolytes to obtain electrical energy. That is, the active carbon adsorbs oxygen or pure oxygen in the air as a positive active material, zinc as a negative electrode, and ammonium chloride or a caustic solution as an electrolyte. Its capacity is 3-10 times higher than other batteries. It has the advantages of stable working voltage and low noise. The charging mode of zinc air electric buses is based on the replacement of zinc powder, which can hold about 300 kilometers per change. Compared with lithium batteries of the same type requiring more than 3 hours per charge, it has large capacity, long life, and low cost. Less pollution and other advantages.

The zinc-air electric bus not only solves the problem that the electric balance of the lithium battery electric bus is difficult to reach the standard, but also solves some long-standing technical problems such as battery stability, leakage, and packaging. At the same time, the cost is only one-half to one-third of lithium batteries.

As a new thing, there are difficulties that need to be overcome. Zinc air battery buses are faced with the need for continuous use after the batteries are unsealed, otherwise the power will drop, and many in-depth problems that have not yet been discovered will need to be continuously improved. The zinc-air electric buses currently developed by Dongfeng have not yet had the capacity for mass production.

As to whether pure electric buses or hybrid buses or pure zinc-air electric buses, which specific technical route is more feasible, this problem should still be addressed to the market.
