摘要:
The invention relates to a cathode for a lithium-sulphur cell, said cathode comprising a current collector (1). A cathode layer system (2, 3) is applied to the current collector (1) in order to achieve a high energy density, current rate and cycle stability, this layer system comprising at least one conductive layer (2) and at least one layer (3) that contains sulphur, and said conductive layer/s (2) being in electrical contact with the current collector (1). The invention also relates to a production method, to lithium-sulphur cells, and to mobile or stationary systems such as vehicles or energy storage installations.

The invention relates to a battery device, in particular a hand power tool battery device, comprising at least one highly functional energy accumulation unit (12a; 12b, 4b; 12c; 12d; 12e; 12f; 12g).
摘要:
The present invention provides a process for producing an electrode (12) for an electrochemical energy storage means, especially for a lithium ion battery (10), comprising the process steps of: a) providing a mixture of starting materials for formation of a lithium titanate; b) calcining the mixture of starting materials to form a lithium titanate; c) adding a component comprising sulphur and optionally lithium to the mixture of starting materials to form a lithium titanate before and/or after the calcining, and/or d) adding a pore former to the mixture of starting materials to form a lithium titanate before and/or after the calcining; e) sintering the calcined product; and f) optionally removing the pore former from the calcined and optionally sintered product. Such a process makes it possible to produce electrodes having a particularly defined pore structure, which enables a particularly good capacity stable over a long period. The invention further provides an electrode for use in a lithium ion battery and a lithium ion battery.
