Abstract
Solid state battery apparatus are provided. The present disclosure relates to a solid state battery comprising a cell which comprises a cathode, an anode, and a solid electrolyte positioned between the cathode and the anode. The anode comprises first particles comprising silicon and second particles comprising a material configured to form an alloy with lithium. The second particles are substantially softer than the first particles and configured to compensate for size changes of the first particles during charging and discharging cycles of the solid state battery such that, as the first particles expand in size, the second particles are compressed in size at a given pressure applied to the solid state battery and further such that, as the first particles shrink in size, the second particles expand in size at a given pressure applied to the solid state battery.
