Batteries supply electrons by undergoing reversible chemical reactions. That has meant that all the reactants have to be inside the battery, which adds to its weight and volume. Lithium-air batteries ...

A research team affiliated with UNIST has introduced a gel-like material that could extend the lifespan and enhance the ...

If you’re reading this with a rechargeable battery powered appliance, the chances are it’s a lithium-ion battery based on intercalation chemistry. But with increasing demands for higher energy density ...

A new type of lithium-oxygen battery could pack more energy and last longer than its predecessors. Lithium-oxygen cells are made of two electrodes, an anode and a cathode, separated by a substance ...

Lithium-oxygen systems could someday outperform today's lithium-ion batteries because of their potential for high energy density. However, a number of important issues, such as their poor ...

The days of gas-guzzling cars may come to an end before we run out of oil if technologies such as 500-mile-per-charge lithium-air batteries become a real and affordable option. A company that ...

The same kind of battery that’s powering your laptop is what powers electric cars. That doesn’t make much sense, so scientists are hard at work on next-gen batteries that will make fears of running ...

Lithium-ion battery fires can be intense and frightening. As someone who used to repair second-hand smartphones, I’ve extinguished my fair share of flaming iPhones with punctured lithium-ion batteries ...
