New Discovery Could Extend EV Battery Life and Range
Researchers identify hydrogen molecule interference as key factor in lithium-ion battery degradation, paving the way for longer-lasting electric vehicles.
- An international team led by the University of Colorado Boulder has uncovered the molecular cause of lithium-ion battery degradation.
- Hydrogen molecules from the battery’s electrolyte displace lithium ions at the cathode, reducing battery capacity over time.
- The findings could lead to the development of more durable batteries, potentially increasing the range of electric vehicles by up to 60%.
- Reducing or eliminating cobalt in battery production can lower costs and address environmental and human rights concerns.
- Future research will focus on solutions like cathode coatings or alternative electrolytes to prevent hydrogen molecule migration.
