The present invention relates to a rechargeable electrochemical battery cell having a housing, a positive electrode, a negative electrode, and an electrolyte, the electrolyte containing sulfur dioxide and a conductive salt of the active metal of the cell. The total quantity of oxygen-containing compounds contained in the cell that are able to react with the sulfur dioxide, reducing the sulfur dioxide, is not more than 10 mMol per Ah theoretical capacitance of the cell.

Rechargeable electrochemical cell

An electrochemical battery cell having a negative electrode, an electrolyte containing a conductive salt, and a positive electrode, the electrolyte being based on SOand the intermediate chamber between the positive electrode and the negative electrode being implemented such that active mass deposited on the negative electrode during the charging of the cell may come into contact with the positive electrode in such manner that locally delimited short-circuit reactions occur on its surface.

Electrochemical battery cell

The present invention relates to a high power battery system having a battery system monitoring electronics and battery modules being electrically connected in series via an operating current line. At least one battery module is a bypass battery module comprising a bypass switch and a bypass line for electrically bypassing the battery module. For each bypass battery module a module monitoring unit of the monitoring electronics monitors the assigned battery module and detects a fault state. In the fault state, the battery system monitoring electronics measures the current flow in the operating current line connecting the battery modules and switches the bypass switch of the bypass battery module concerned from a normal operating position to a bypass position at a time when the current flow in the operating current line is lower than a predetermined limit value.

High-current battery system and method for controlling a high-current battery system

The invention relates to a rechargeable electrochemical battery cell having a negative electrode, an electrolyte, and a positive electrode. The negative electrode comprises an electronically conductive substrate () at which an active metal () of the negative electrode is deposited by electrolysis during the charging of the cell. A porous structure () that contains the active mass () of the positive electrode is arranged in the vicinity of the substrate () of the negative electrode () in such a manner that the active metal () of the negative electrode that is deposited during the charging of the cell () penetrates into the pores () of the porous structure () comprising the active mass of the positive electrode and is deposited further therein, at least in part, in metallic form.

Rechargeable electro chemical battery cell

Electrolyte for an electrochemical battery cell that contains sulphur dioxide and a conductive salt. The electrolyte is a gel that is formed with to the involvement of a fluorosulphinate. The invention is also directed to a battery cell that contains such an electrolyte.

Electrolyte for an electrochemical battery cell

The invention relates to a rechargeable electrochemical battery cell. Said cell comprises a negative electrode (), an electrolyte (), and a positive electrode, the negative electrode () having a an electronically conductive substrate (), onto which an active mass () is electrolytically deposited during the charging of the cell. The aim of the invention is to significantly improve the operational safety of said cell. To achieve this, the cell in contact with the substrate ()of the negative electrode () has a porous structure ()formed by solid particles (), which is configured and positioned in such a way that the active mass (), which is deposited during the charging of the cell, penetrates from the surface of the substrate () into the pores () of the latter and is deposited again therein.
