Modeling Stack Pressure Effects on Interfacial Void Growth in Solid-State Lithium Anodes
Maintaining 5 MPa stack pressure suppresses lithium void growth during high-rate stripping while active spring packs prevent separator fracture.
Stress Coupled Phase Transformations and Energy Efficiency Losses in Silicon Anode Cells
Silicon anode cells suffer 10 to 25 percent energy efficiency losses from stress-coupled thermodynamic hysteresis unrecoverable by rate reduction.
Thermodynamic Phase Transitions and Voltage Hysteresis in Lithiated Silicon
Voltage hysteresis in lithiated silicon is a thermodynamic and stress-coupled phase phenomenon requiring strict cut-off limits to prevent crystallization.
Thermodynamic Principles of Crystalline Phase Transformations in Silicon Anodes
Silicon anode lithiation requires voltage cutoff management above 50 mV vs Li/Li+ to prevent c-Li15Si4 crystallization and severe mechanical capacity loss.
