ELECTRODE PRECURSOR COMPOSITION

An electrode precursor composition for an alkali metal ion secondary cell is described. The composition includes a polymer-solvent gel matrix phase and a dispersed phase containing an electrochemically active material. The electrochemically active material has a multimodal particle size distribution having a D/Din the range 2 to 15. The electrode precursor composition can be processed into an electrode for an alkali metal ion secondary cell, for example a lithium ion secondary cell.
