Lithium Metal Polymer battery
The elementary electro-chemical cell of Lithium Metal Polymer battery (LMP battery) is based on the utilisation of four
This completely solid elementary cell is built on two reverse-function electrodes : anode ensures the supply of lithium
ions during discharge and cathode acts as a receptacle where lithium ions come slotting in. These two electrodes are separated by a
solid polymer electrolyte which conducts lithium ions. Conductivity of ions is carried out by dissolving lithium salts in polyoxyethylene.
To obtain optimal conductivity, temperature of the battery must be maintained between 80°C and 90°C.
Anode is in lithium metal whereas cathode is made of a material composed of vanadium oxide, electrolyte and carbon
which, form a plastic composite. A current collector connected to cathode provides electric connection.
