MS Lithium-Ion Rechargeable Battery <3V Type>
FEATURES
Sll own developed MS(Manganese Silicon) Lithium-ion rechargeable battery addresses the demand most effectively.
The battery uses silicon oxide as anode and lithium manganese composite oxide as cathode. As a result, it offers twenty
times the capacity of conventionally available batteries, in addition to longer cycle-life and highly stable over-discharge
characteristics.
