How to get to the bottom of how the graphene cell in a lithium battery works
A lithium battery uses a metal oxide called graphene, a material with excellent electrical conductivity and high energy density.
The material has also been found to be flexible, which could allow for future flexible batteries.
But there’s no guarantee it won’t be vulnerable to corrosion, and researchers are still looking for ways to prevent it.
To understand how that happens, a team of researchers led by Bongchao Huang of the University of California, Berkeley, have developed a new process that turns graphene into a liquid.
The researchers found that when a drop of graphene is placed in a water bath, the graphene expands to a larger size and begins to solidify.
It can then be transferred into a battery cell, where the metal oxide can separate into a thin film that can then solidify into a membrane.
The new process is already being tested in a liquid battery.
The technology could be useful for other types of batteries, including ones that store electricity for longer periods, such as batteries for electric cars.
