Cartilage could be key to safe 'structural batteries'

Your knees and your smartphone battery have some surprisingly similar needs, a University of Michigan professor has discovered, and that new insight has led to a "structural battery" prototype that incorporates a cartilage-like ...

Building better batteries by borrowing from biology

A research team at Osaka University has reported a new advance in the design of materials for use in rechargeable batteries, under high humidity conditions. Using inspiration from living cells that can block smaller particles ...

Scientists reveal the hidden costs of cobalt mining in DR Congo

In recent years, the demand for cobalt, a crucial component of rechargeable lithium-ion batteries for smartphones and electric cars, has been on the increase. Around 60 percent of the world's cobalt supply comes from the ...

Optimizing lithium-sulfur battery electrolytes for long life

In the future, lithium-sulfur (Li-S) rechargeable batteries could hold more energy and cost less than lithium-ion batteries if they can be made to last longer. A key challenge is preventing the polysulfide ions that must ...

Silicon as a new storage material for the batteries of the future

Longer life times, larger ranges and faster recharging—developments such as electric mobility or the miniaturisation of electronics require new storage materials for batteries. With its enormous storage capacity, silicon ...
