Process for producing an electrode for an electrochemical energy storage means and electrode
The subject matter of the present is a method for manufacturing an electrode for an electrochemical energy reservoir, in particular for a lithium-ion battery, encompassing the method steps of: a) furnishing a mixture of initial substances for formation of a lithium titanate; b) calcining the mixture of initial substances for formation of a lithium titanate; c) adding to the mixture of initial substances for formation of a lithium titanate, before and/or after calcination, a component encompassing sulfur and optionally lithium; and/or d) adding a pore former, before and/or after calcination, to the mixture of initial substances for formation of a lithium titanate; e) sintering the calcined product; and f) optionally removing the pore former from the calcined and optionally sintered product. Electrodes having a particularly defined pore structure can be generated with a method of this kind, thereby making possible particularly good capacity that is stable over the long term. A further subject is an electrode for use in a lithium-ion battery, as well as a lithium-ion battery.
