Neue Elektrodenmaterialen mit Lithium Interkalation auf Basis von Orthosilikatsderivaten

摘要

Orthosilicates containing the SiO 4 4- tetranion as the building block are used as redox materials by incorporation of at least one transition elements with at least two valency levels. Lithium ingresses or egresses from the structure to compensate for the valency change of the redox couples during electrode operation and keep overall electroneutrality.
