Overview of 3.0V Pouch Li-MnO2 Cells
3.0V pouch Li-MnO2 cells represent a significant leap in lithium-based battery technology. Unlike traditional lithium-polymer (LiPo) cells, these batteries utilize a lithium anode combined with a manganese dioxide (MnO2) cathode. This chemistry provides a stable and reliable power source with distinct advantages over other battery types.
