What Are The Technology Advantages?

High Energy Density
To meet the market need for smaller and thinner cells with better run times, Yok Energy is constantly working to develop improvements in energy density. To meet the design requirements of smaller size and larger capacity for competitive device markets.
High Power
With features including excellent high power capability, low internal resistance and long cycle life, Yok’s High Rate Li-ion polymer cells enable our customers to make lighter, more powerful and durable devices.
Fast Charging
Yok Energy can provide fast charge batteries without compromising long cycle life and high safety standards. The charging speed is several times faster than conventional standard cells.
Special Shaped Cells
Custom shaped batteries can be small and thin, with high energy density. Battery shapes are enabled by using our advanced stacking process, so that batteries can be adapted to the internal shape spaces of devices.


Safe and Consistent Over The Full Life Cycle

The safety and performance of lipo batteries are of paramount consideration when designing or updating an electronic device. As a manufacturer, you need to have the confidence and reassurance that the lithium battery will give optimum performance. During use, this includes a steady discharge of energy without overloading, with a long lifecycle. During downtimes, the batteries are recharged quickly and efficiently, without the risk of overcharging. YOK Energy builds all these considerations into the overall design of every customer battery design.
