Li-ion pouch cells
Bestgo Battery makes high quality Li-ion pouch cells which have thin shape for heat passing and internal resistance reduction. The package foil of cells is a type of aluminum and elastic fibers mixed material which comes from Japan based company (Showa). The aluminum improved the heat passing efficiency, the strong elastic fibers make foil has good strength and tolerence. In extreme condition if cells damaged and generated heat and gas, the package foil can be blown up to hold them but not allow any liquid or gas leak out, this is a very nice safety design.
To enhance the safety reliability, we applied an unique step in manufactuing that is arrange all half-made cells in 75 degree Celsius oven for 2 hours as a high temperature tolerence test. Our unique chemistry formula and nice materials will help cells pass the test. Then we promise pouch cells made by us are quality reliable in high temperature condition as we specified. The electrolyte of our pouch cells are semi-solid state which better than liquid type that may have risk of leak out of cell.
The Li-NCM cells (Lithium Nickel Cobalt Manganese Oxide based) we offered has high energy density, they are suitable to make light and impact battery packs. We have done some improvements in battery materials, which make our cells have abundant safety tolerance and good consistency. Battery packs made with our Li-NCM cells are the best candidate to replace lead acid batteries because they have good cycle life, powerful energy, light weight and small in size, they can be widely used in portable tools, vehicles and boats etc. The EV type Li-NCM cells made by us are built for battery packs which now quipped on hundreds of electric buses running in every day.
The LiFePO4 (lithium iron phosphate) cells we offered has long cycle life and high safety assurance. Some of 10Ah LiFePO4 pouch cells made in 2011 have cycled about 4000+ times with 100% DOD in test lab. For now we are making 30Ah and 25Ah cells which are designed for high safety assurance and consistency, which will be used in long life energy storage systems etc.
