The researchers believe that this elastomeric electrolyte system can be broadly used in the operation of several different post-metal batteries, including metal–sulfur, and metal–air batteries, due to its high ionic conductivity and outstanding mechanical properties.
Researchers may have found a promising alternative to conventional lithium-ion batteries made from a common material: rubber. For electric vehicles (EVs) to become mainstream, they need cost-effective, safer, longer-lasting batteries that won't explode during use or harm the environment.
“Rubber has been used everywhere because of its high mechanical properties, and it will allow us to make cheap, more reliable and safer batteries,” said Lee. “Higher ionic conductivity means you can move more ions at the same time,” said Michael Lee, a mechanical engineering graduate researcher.
In the US, meanwhile, researchers at the Georgia Institute of Technology have developed rubber electrolytes for EV batteries, which they say will make them more cost-efficient, safer and longer-lasting.
These unique characteristics of the rubber electrolytes prevent lithium dendrite growth and allow for faster moving ions, enabling reliable operation of solid-state batteries even at room temperature.

Now the Georgia Tech engineers have solved common problems in the ring with an in-between electrolyte, calling it a ‘rubber electrolyte’. It was allowing the material to form a three-dimensional (3D) interconnected plastic crystal phase within the robust rubber matrix.
The researchers believe that this elastomeric electrolyte system can be broadly used in the operation of several different post-metal batteries, including metal–sulfur, and metal–air batteries, due to its high ionic conductivity and outstanding mechanical properties.
The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries). In a new study, the researchers showed that this material, which could be produced at much lower cost than cobalt-containing batteries, can conduct electricity at similar rates as cobalt batteries.
