Abstract
An orthosilicate whose structure is based on SiO.sub.4.sup.4 tetranions which contains at least one transition element with at least two valence states. Lithium ingresses or egresses into or from the structure in order to compensate for a change in valency of the redox couple during electrode operation and thereby maintain overall electroneutrality.
