VERFAHREN ZUM LADEN EINER LITHIUMIONEN-BATTERIE MIT EINER NEGATIVEN ELEKTRODE

摘要

The charging procedure, for use with a lithium-ion battery having a negative electrode and a functioning potential of over 0.5V relative to the Li+/Li ratio, uses a first charging stage at a constant tension of between 2 and 5 volts, preferably below a limit of about 3.5 volts for a duration of 5 minutes. The battery's negative electrode is based on Li 4Ti 5O 12 and the type of battery can be LiMO 2, where M = Mn, Co, Ni or a mixture of these materials and having a constant tension of over 2.7V.
