Breakthrough: Single-Crystal Electrolytes Revolutionize Solid State Batteries

Koike of Japan and the Japan National Institute of Advanced Industrial Science and Technology (AIST) have made a significant breakthrough in the development of solid-state batteries. They have created a single-crystal material that could potentially be used as an electrolyte in these batteries.

The company is now preparing to sample the new material to battery manufacturers, with the goal of starting production in 2027/28. This innovative material is said to reduce electrical resistance by a remarkable nine-tenths when used as a battery electrolyte.

In order to prevent degradation, a liquid is applied to the electrodes, transforming the battery into a type of "semisolid-state" battery that combines both solid and liquid components. This unique design enhances the overall performance and longevity of the battery.

One of the most exciting applications of this new material is its potential use in pacemakers. By incorporating this material into the battery of a pacemaker, its lifespan could be extended from the current 10-15 years to an impressive 50 years. This breakthrough could greatly benefit individuals who rely on pacemakers for their cardiac health.

Koike, a company known for producing monocrystalline wafers, has successfully developed monocrystals with a diameter of 25mm specifically for use in batteries. This achievement further demonstrates their commitment to advancing battery technology and contributing to the development of more efficient and durable energy storage solutions.
