Abstract
Solid-state lithium-ion cells described herein can operate at pressures. In some embodiments, the solid-state lithium-ion cells undergo little or no volume change during cycling. A conditioning process that that significantly improves the performance of a cell at reduced pressures can involve cycling the cell at high pressure.
Claims23
A method comprising:
- providing a solid-state lithium-ion battery cell comprising an anode film, the anode film comprising particles of anode active material in contact with particles of inorganic solid electrolyte;
- performing a high-pressure conditioning process comprising a plurality of charge/discharge cycles wherein an applied pressure between 2 and 10 MPa is maintained on the solid-state lithium-ion battery cell;
- and
- removing the applied pressure, wherein after removing the applied pressure, the cell is conditioned for operation.
