While Li-Ion and Lithium polymer electrolyte (LiPo) batteries possess unmatched energy density, Lithium-based batteries are costly to produce and need meticulous handling along with a cautious charging. With the advancement of nanotechnology, the manufacturing process of the cathode electrode for these batteries has seen a substantial improvement. The break through nanotechnology-based high-load LiFePO4 cells are […]
