Battery systems based on alkali metal anodes and solid solution cathodes, i.e., cathodes based on the insertion of the alkali cation in a "host lattice," show considerable promise for high energy density storage batteries. This paper discusses the interaction between battery requirements, in particular for vehicle propulsion, and electrochemical and constructional factors. It is argued that the energy obtainable at a given load is limited by saturation of the surface layers of cathode particles with cations, and that the time before saturation occurs is determined by diffusion of cations and electrons into the host lattice. Expressions are developed for plane, cylindrical, and spherical particles, giving the relation between battery load and the amount of diffusion needed. Numerical solutions are provided and these are discussed in terms of engineering applications.
