Li-ion batteries
“Research and Technology Centre “ANK” Ltd used many years of experience with batteries,so it began developing batteries based on lithium-ion cells of European quality Li / LiFePO4 with a nominal capacity of 100 Ah. This type of cells is suitable for creating batteries designed for both electric vehicles and backup power supply. “ANK” uses lithium iron phosphate (LiFePO4) as the cathode material.
