VANADIUM RECHARGEABLE LITHIUM BATTERIES (VL SERIES)
MANGANESE RECHARGEABLE LITHIUM BATTERIES (ML SERIES)
GENERAL DESCRIPTION
Panasonic vanadium rechargeable lithium batteries are
compact, high energy secondary batteries that have
nearly twice the energy of conventional button-shaped
Ni-Cd batteries.
GENERAL DESCRIPTION
These super compact lithium secondary batteries
feature a new configuration in which a manganese
compound oxide is used for the positive electrode,
and a lithium/aluminum alloy for the electrode.
