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

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.

Water processing method, in particular for producing fresh water from salt water by membrane distillation. In comparison with previously known methods, a significant reduction in investment cost and operating cost can be achieved by the combination of the following measures:

Method and device for the purification, especially desalination, of water

Rechargeable battery cell operable at normal temperature, with an SO.sub.based electrolyte system, a negative electrode and a positive electrode, wherein one of the electrodes has an electronically conductive discharge element. An improved cycle stability and consequently a longer useful lifetime is achieved in that, as a reaction protection material to protect the discharge element against unwanted reactions with constituents of the SO.sub.based electrolyte system, at least a surface layer of the electronically conductive discharge element contains an alloy of chrome with another metal and/or a protective metal, selected from rhodium, tungsten, rhenium, tantalum, platinum, iridium, osmium or technetium in pure form, as an alloy or as a constituent of a compound and/or a carbide, nitride or phosphide of titanium, nickel, cobalt, molybdenum, iron, vanadium, zirconium or manganese.
