2023-10-24 10:25:52 曾路

Battery features: lamination technology, stability, long battery life

Capacity of 550 mah

Maximum discharge current :1C, pulse :2C

For smartwatches, 70,000 per case.

Customer demand: high capacity, long battery life, safety.


Solutions: 1. Security

◆ adopt gmb-Q300c generation machine, an automatic equipment developed by GMB, with imported separation paper, produce positive pole packaging bag like positive plate, fully seal the positive pole plate of the battery;

lithium Batteries


◆ adopt Taiwan high precision die-cutting to eliminate the burr of the pole sheet and avoid the internal micro short circuit of the battery;

◆ for the segmented pole slice, the unqualified pole slice shall be scrapped through the secondary projector inspection.

The finished battery is punctured


2. High capacity:

Adopt kian mature high voltage scheme, increase capacity by 15~20%;Batteries meet customer requirements:

No.
