Claims29
An electrochemical cell, comprising:
- a housing;
- a negative electrode in the housing;
- a positive electrode in the housing;
- and
- a separator between the negative and positive electrodes,
- wherein the positive electrode has a first portion comprising a catalyst and a first concentration of wax, and a second portion comprising a catalyst and a second concentration of wax, the second concentration being different than the first concentration.
3 more elements
A method of making an electrochemical cell, comprising:
- incorporating a wax into a positive electrode such that the positive electrode has a first portion comprising a catalyst and a first concentration of wax, and a second portion comprising a catalyst and a second concentration of wax, the second concentration being different from the first concentration;
- and
- incorporating the positive electrode into the cell.
