    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.
