The positive electrode is made of metal Oxide, the negative of Carbon. Other metals such as Nickle, Cobalt or Mangnese are also used. Because the Lithium-ions are smaller, only they can pass from one side to the other through the special separator.

Lithium and water, this provides a strong reaction with the danger of fire for both the accumulator and the car. For this reason, the electrolyte solution is free of water. Moreover, in the meantime, there are membranes as separators which have the finest ceramic platelets and can withstand a temperature of 600°C, at the same time, still remaining movable.

The voltage range (2,5 V- 4,1 V) must always be maintained when charging/discharging, otherwise the accumulator cell will be destroyed. A suitable protective circuit is integrated into the AC/DC-inverter. 12/10
