Heat can make Li-Ion batteries explode. Or restore their capacity, say Chinese boffins
Summary
A recent study by researchers at China’s Ningbo Institute reveals an unexpected use of heat in Lithium-Ion (Li-Ion) batteries. They have found that heating these batteries to temperatures above 150°C can actually restore their energy density, effectively reversing the decline in capacity caused by regular charge and discharge cycles. Typically prone to issues like thermal runaway, the research opens new avenues for enhancing battery lifespan and performance.
Key Points
- Heating Li-Ion batteries to 150-250°C can restore their capacity, contrary to traditional beliefs about battery thermodynamics.
- The research aims to address the problem of battery degradation that occurs over time.
- It also raises concerns about thermal runaway, a dangerous condition that can lead to fires.
- Future battery technologies could utilize modified charging techniques to rejuvenate older batteries.
- This breakthrough could potentially lead to longer-lasting electric vehicles and self-healing devices.
