  • Mechanical degradation is an undesired behaviour for battery electrode materials such as lithiated silicon. Here, the authors performin situnanomechanical experiments and atomistic modelling to reveal the damage tolerance of electrochemically lithiated silicon.

  • Stack pressure controls porosity during Li alloying/dealloying. A threshold pressure is needed for the densification and stable cycling of Li alloys in batteries, leading to the design of Li alloy anodes with densified interfacial layers for cycling at low pressures in solid-state batteries.

  • While solid-state lithium-ion batteries offer promising energy densities for safe energy storage, typical solid electrolytes show poor room-temperature ionic conduction. Now the origin of the superionic transition observed in Li3YCl6-type Li-ion conductors is revealed by in-depth crystal structure characterizations and improved ionic conductivities achieved by lowering the transition temperature.
