Preventing oxygen release leads to safer high-energy-density batteries
A research group has produced fresh insights about the release of oxygen in lithium-ion batteries, paving the way for more robust and safer high-energy-density batteries.
Next-generation batteries that store more energy are critical if society is to achieve the UN's Sustainable Development Goals and realize carbon neutrality. However, the higher the energy density, the higher the likelihood of thermal runaway - the overheating of batteries that can sometimes result in a battery exploding.
Oxygen released from cathode active material is a trigger for thermal runaway, yet our knowledge of this process is insufficient.
