A team of researchers at the Kyoto University, with the collaboration of Sharp, develops a new material that can significantly extend the operating lifespan of Lithium batteries.
A joint research project between Kyoto University Graduate School of Engineering and Sharp Research and Development Center has unveiled a new material composition for Lithium batteries, which is reported to extend their operating lifespan to at least 70 years.
Normally, research into materials and chemical composition of batteries requires high-throughput screening, a trial-and-error type testing method that analyzes and observes hundreds, if not thousands of combinations and/or permutations in search for the most efficient results. The material composition of the new Lithium battery was achieved using the same method, albeit with a particular focus on the material’s atomic structure.
The new material composition was experimentally tested, and was fabricated successfully using a sol-gel process. Upon testing, the material was found to have 6 times more maximum charge cycles than other material compositions normally used for Lithium batteries. Its 25,000 cycle durability, when equated with at least one complete deep cycle per day, could enable the battery to last for about 70 years.
While the cycle numbers may not mean much for smartphones and other mobile devices in general (whose batteries usually function optimally only for a few years), its uses are most evident in larger scale applications. Mobile energy systems and electric cars could benefit from its extended cycle durability, economizing the use of both in the long run.
Additionally, the researchers also looks into shortening the manufacturing process of standard Lithium batteries, using the same unique material composition that they have developed.
