Chaowei has more than 20 years of research and development experience, has participated in the formulation of 11 national and industry standards, established a large number of civilian scientific research institutions in China, its battery products annual sales in the country second, research center data shows that Chaowei electric bicycle battery products in China market share of more than 40%, is a veritable electric bicycle battery leading enterprise in China.
Chaowei battery is still based on lead-acid battery products, there are black gold series, silver alloy series, Chaowei No. 1 series optional, these series are mainly the difference between the electrode and the internal components of the grid, the lithium battery is responsible for the subsidiary Zhejiang Chaowei Chuangyuan, and the lithium battery products are designed to replace the same type of lead-acid battery, but it has not formed a series.
Chaowei's silver alloy series battery is its star product, adding a small amount of silver to the battery alloy grid to strengthen corrosion resistance, improve and enhance the battery's deep discharge cycle performance and conductivity, and increase battery capacity.
However, compared with the silver alloy series, the "black gold series" is the product line that Chaowei pays the most attention to. Chaowei Group will launch an iteration of the black gold series every year; The selling point is that the battery cells contain graphene materials, but so far all brands of graphene batteries are quite different from the real graphene batteries.
According to the industry nomenclature principle, the battery of graphene as the positive and negative electrode material is the graphene battery, and the graphene in the "black gold series" battery is only similar to additives, and the main role in the battery is to improve the conductivity of the electrode or the thermal conductivity and heat dissipation characteristics, and it is not the active material of the positive and negative electrodes of the battery, and its core energy storage mechanism has not changed due to the addition of graphene, so it is not appropriate to call it a graphene battery, so it can also be regarded as a marketing gimmick.
Although the concept of "graphene battery" is of little practical significance, Chaowei does not charge consumers an additional "IQ tax", and the price of its battery is between 400-700 yuan, but the e-commerce platform has a coupon subsidy for a long time, and the price is not much different from that of ordinary lead-acid batteries.
