Abstract
A method of manufacturing a battery cell includes forming an electrode and coating the electrode with a n-mer solution. The n-mer coated electrode is treated by heat, ultraviolet, or cross linking agents to polymerize the n-mer and form an ion exchange material that covers at least some of the electrode.
Claims16
A method of manufacturing a battery cell, the method comprising:
- forming an electrode comprising zinc particles and operable as a negative electrode in the battery cell;
- coating the electrode with an n-mer solution such that the n-mer solution forms a layer over the electrode and at least partially embeds into the electrode after coating the electrode with the n-mer solution;
- and
- curing the n-mer solution thereby forming an ion exchange coating partially embedded into the electrode and contacting at least a portion of the zinc particles of the electrode;
- and
- soaking the electrode with the ion exchange coating in a solution comprising hydroxide anions, thereby at least partially replacing n-mer anions with the hydroxide anions and converting the ion exchange coating into a hydroxide-based ion exchange coating.
