Abstract
Pressure relief mechanisms can provide an outlet for cathode pressure buildup during battery operation. Mechanical cathode modifications can control cathode interfaces during battery operation. Pressure relief mechanisms and mechanical modifications can be utilized to improve performance, longevity and/or to prevent failure of batteries, such as during cycling of liquid metal batteries.
