Claims20
An electrode composition comprising an electrochemically-active polymer.
An electrode composition for an electrochemical cell, the electrode composition comprising polymer-coated redox-active particles.
A method of operating an electrochemical cell in a temperature range of −20° C. to 60° C., the method comprising:
- absorbing or releasing heat into redox inactive materials inside the cell, absorbing or releasing heat into redox inactive materials outside the cell, inhibiting or improving one or more reactions via one or more catalysts and/or dopants in the cell, and/or controlling ionic conductivity at lower or higher temperature via one or more redox inactive electrode components in the cell.
An electrochemical cell comprising an electrode comprising a phase change additive.
An electrochemical cell comprising an electrode comprising a binder or emulsifier, wherein the binder or emulsifier is cross-linked or has been passivated such that the binder is stable at relatively higher temperature.
An electrochemical cell comprising an electrode comprising redox active particles coated with a thermally stable encapsulant.
