Abstract
The relevance of materials science to the development of high-energy secondary batteries is discussed with reference to the complex highly defective disordered solids such as PbO

, which exhibit high conductivities for both lithium ions and electrons. The prospects for incorporating these materials into completely solid state secondary batteries are discussed. An assessment is also given of the current status of solid lithium ion electrolytes and the behaviour of solid electrolyte/insertion electrode interfaces. A final section outlines the probable configuration of solid state batteries and emphasizes the need to optimize the properties of composite electrodes incorporating solid electrolytes and insertion electrode components.
