Nanotechnoloy – Nano coating prevents exploding Li-ion batteries

Lithium-ion batteries are very popular as they're lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately,...

Next-generation smartphone battery inspired by the gut

A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. @...
