A grade battery cell is generally to make the factory using the battery cell directly place an order to
the battery cell factory. The battery cell factory arranges production according to the factory's own
production capacity and technical ability. After a series of battery cell manufacturing processes, the
final production delivered to the customer. Before placing an order, the battery production plant
generally communicates battery capacity, thickness, length, width and other parameters.
Then the battery made completely according to the standard of the order is called A grade cell.
Any factory producing products must have a defect rate. Then this defect rate determines the vitality
of a factory. In the lithium battery industry, purely technology, ingredients, etc., there will not be a big
gap between the first-line lithium battery and the third-line lithium battery factory, but in the production
process and production process, the The gap between the NPL ratio is very large, the first-tier
manufacturers can achieve about 2%, while the second and third-tier manufacturers are likely to
achieve 5-10%. It is precisely because of this defect rate that grade B cell is created.
