Abstract
The invention relates to a lithium ion cell, comprising a positive electrode which contains a chalkogen compound, containing lithium, of a transition metal, a non-aqueous electrolyte and a negative electrode which is separator-isolated and contains carbon, which is characterized in that the cell contains lithium metal or a lithium alloy in a form physically separated from the electrodes, the lithium metal or the lithium alloy having a connection for the main lead of an electrode and, via the electrolyte, an ionic connection for the electrodes.
Claims10
A lithium ion cell, comprising:
- a positive electrode containing a chalkogen compound, containing lithium, of a transition metal;
- a non-aqueous electrolyte;
- a separator-isolated negative electrode containing carbon;
- and
- lithium metal or a lithium alloy in a form apart from the positive and negative electrodes, the lithium metal or the lithium alloy having a connection for the main lead of an electrode and, via the electrolyte, an ionic connection for the electrodes.
