    2020-01-20 11:44:20 32

    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;

    Markyn 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.
