Effect of Compressive Stress on Electrochemical Performance of Silicon Anodes

In this study, we report on the effect that an externally applied compressive stress has on the electrochemical performance of Sianodes.Usingthecompressionofanall-solid-statecellasaconvenientformatforsimulatingvolumeconfinement,theelectrochemicalperformance of Si anodes as a function of externally applied compressive stress has been systematically investigated. We verify thatthe extent of Si lithiation is limited by confining the free volume expansion of nano-Si particles. Volume confinement of Si particlesis manifested as an overpotentialand results in a stable anode forlithium-ion batteries. These results are foundationaland lead to thebest understanding to date of the complex electrochemomechanics of a Si-based anode.© 2012 The Electrochemical Society.
