Description:
Market Opportunity
USC researchers have developed iron based electrodes with stabilizing surface modifications that remain operational in alkaline and oxidizing conditions. Coated with either nickel or cobalt, the modified electrodes are capable of normal operation for over 1000 hours with no changes in electrode potential or impedance. Batteries manufactured with these electrodes will be cheaper to produce while maintaining performance and sustainability.
USC Solution
Alkaline batteries power a wide variety of electronics and devices in single use or rechargeable formats. Nickel is the metal of choice for making electrodes due to its high conductivity and stability in alkaline media, but it is relatively expensive compared to other metals. Other metals, however, undergo oxidation, dissolution, or form insulting oxide films in alkaline conditions, making them unsuitable for battery construction. Improvements to lower costs of manufacturing can boost competitiveness in the saturated $2.3 billion alkaline battery market.
Value Proposition
- Cheaper to manufacture compared to nickel electrode alkaline batteries
- Comparable performance to current standards
Market Application
- Reduces cost of manufacturing alkaline batteries
