Details
Storage conditions (vacuum sealing or using self-sealing bags in a glove box, especially for high-nickel and sodium electrode materials, improper storage may lead to increased internal resistance).
Fold marks: Single-sided electrode sheets may curl after rolling, and flattening and packaging may cause fold marks.
The electrode sheets are made of nickel-cobalt-manganese NCM622-C (single crystal), and the electrolytes used during testing are 622 deduction electrolyte and ternary electrolyte (KLD-1230C).
The electrode sheets need to be rolled (it is recommended to roll according to the lowest parameter range of the corresponding electrode sheet compacting), baked at 105°C for 4 hours after punching, left to stand for 8 hours after injection, and the positive electrode sheet needs to be pressure-sealed at 0.02C during constant current charging testing, with a sealing pressure of 1300 psi.
This product must be tested in accordance with the test methods and electrolytes recommended by
Canrd to achieve the corresponding performance.Since the test method and electrolyte have a great
influence on the performance of the battery, any change in the test method or electrolyte may reduce
the performance of the pole piece; be sure to check this information before purchasing.
