Brief overview of lithium-ion HV batteries

A lithium ion battery cell consists of an anode (carbon, copper foil), a separator (porous polyolefin foil, ceramic-coated), a
Introduction
cathode (lithium metal oxide, aluminum foil) and an electrolyte (organic solvents, lithium conducting salt, additives). During
charging, the lithium ions migrate from the cathode to the anode and are stored there.

Technology The electrical energy is converted into chemical energy. During the discharge process - to operate the electric motor - the lithium
ions migrate back to the cathode. The chemical energy is then converted back into electrical energy. Lithium-ion high-voltage batteries are based
on sophisticated technologies which make

New Standards
No capacity loss when only charging or discharging the battery

E-Readiness Longer life cycle than other battery types on the market
Rollout 27
Low self-discharge in periods of inactivity

Maintenance-free due to the lack of mechanical wearing parts
Glossary
High capacity and low weight in comparison to other battery types
