Overheating batteries are a serious risk, in the worst cases leading to fires and explosion. A team including researchers from the University of Tokyo has developed a simple, cost-effective method to test the safety of lithium-ion batteries, which opens up opportunities for research into new and safer batteries for the future. The researchers created an intentionally unstable battery which is more sensitive to changes that could cause overheating. The battery is one-fiftieth the size of conventional batteries, so is less resource intensive and tests can be carried out in a smaller lab environment.
Researchers from Harwell Science and Innovation Campus explore methanol dynamics in copper-loaded zeolites using neutron scattering, revealing insights into diffusion behavior and its impact on catalytic processes.
As global temperatures warm, the Southern Ocean – between Antarctica and other continents – will eventually release heat absorbed from the atmosphere, leading to projected long-term increases in precipitation over East Asia and the Western U.S., regardless of climate mitigation efforts.
