Sorting and sorting are mainly used to test and sort the internal pressure and resistance of battery cells. Battery sorting machines are generally used.
Capacity classification refers to the lithium-ion battery capacity detection and charge-discharge cycle aging test, and the capacity classification cabinet is generally used.
The technological process of 3C lithium battery can be divided into positive electrode paste, negative electrode paste, positive electrode sheet, negative electrode sheet, steel case assembly, injection of liquid, testing, packaging, etc. In the second half of the process flow, the formation and capacity division of 3C lithium batteries is related to whether the battery core consistency, efficiency rate and other indicators can meet the requirements and constitute a taxable partrtant of the detection of the activation of the battery core. During the test, the shrapnel microneedle module can be used as a current transmission medium, which can stabilize the connection. The performance tests of 3C lithium batteries include basic performance, safety performance, environmental performance and electrochemical performance. During the test, the shrapnel microneedle module can transmit current between 1-50A, with strong overcurrent capability and an average of 20W. The battery life can effectively improve the efficiency of testing 3C lithium batteries and ensuring efficient and safe testing.
