Aim 5: Corrosion
Mitigate corrosion of both electrode materials and current collectors to enable durable aqueous batteries.
A critical barrier to realizing long-life batteries is corrosion of both electrode materials and current collectors. Despite its importance in limiting commercialization of many different battery chemistries – particularly aqueous batteries – a large knowledge gap about corrosion still exists.
Corrosion is defined here as any unwanted decomposition or conversion of material as a result of chemical or electrochemical reaction with its surroundings that leads to loss of efficient electricity transfer. Corrosion is caused by complex mechanisms. It can be caused by electric currents, the solubility and dissolution of materials in water, reaction of the current collectors, the small but continuous reaction of water with the highly reductive anode and oxidative processes at the cathode leading to water splitting into hydrogen and oxygen.
The Aim 5 team seeks to limit, as much as possible, the corrosion of the electrodes and current collectors for enabling long-life aqueous batteries.
