Lithium-ion energy storage and method for equalizing potentials of a measuring section and a main section of the lithium-ion energy storage

摘要

The present invention relates to a lithium-ion energy store, comprising an electrode with a main section and with a measuring section electrically separated from the main section, a counter-electrode and a separator between the electrode and the counter-electrode, wherein a measuring cell which is part of the lithium-ion Energy storage forms, the measuring section of the electrode, a counter electrode measuring section, which is opposite to the measuring section of the electrode with respect to the separator, and arranged between the measuring sections of the electrode and the counter electrode measuring section portion of the separator, and a main cell, the one Part of the lithium-ion energy accumulator, the main portion of the electrode, forms a counter electrode main portion facing the main portion of the electrode with respect to the separator and a portion of the electrode disposed between the main portion of the electrode and the counter electrode main portion Separators comprises, wherein the lithium-ion energy storage comprises an adjusting device, with which an electrical potential of the measuring section and an electrical potential of the main section are equal to each other.
