摘要: A method of producing an electrochemical cell includes introducing lithium into the electrochemical cell such that an amount of mobile lithium contained in the cell available for incorporation and releasing processes in electrodes exceeds, after formation, the capacity of at least one positive electrode for taking up lithium at least by a factor of 1.1, and the at least one negative electrode in terms of its capacity for taking up lithium is dimensioned to a size sufficient to be capable of taking up the entire mobile lithium contained in the cell after formation, wherein the lithium is introduced at least partially into the electrochemical cell via the at least one negative electrode by pre-lithiating the at least one negative electrode prior to combination with the at least one positive electrode or by applying metallic lithium on a surface of the at least one negative electrode.

摘要: A composite material includes an electrochemically active organic material and an electrochemically active inorganic material. The organic material contains subunits according to formulae (I) and/or (II) wherein n is an integer not smaller than 2, Y represents an amide group (—NH—CO— or —CO—NH—), an ester group (—O—CO— or —CO—O—) or a urethane group (—NH—CO—O— or —O—CO—NH—), R1, R2, R3 and R4 each independently represent H, alkyl (preferably —CH3, —C2H5), alkoxy-(preferably —OCH3, —OC2H5), -halogen or —CN, Ar1 and Ar4 independently represent a bridging aryl group, Ar2 and Ar3 independently represent a non-bridging aryl group, and R5 is a bridging alkyl, alkene or aryl group.
