As an important basic support for digital products and new energy batteries, many people are looking forward to a substantial breakthrough in lithium battery technology. According to reports, Japan, where the first modern lithium battery was invented, has finally made important progress. Specifically, Noriyoshi Matsumi, a professor at Hokuriku Advanced Institute of Science and Technology in Japan, led a team to develop a new type of adhesive made of bisimino-naphthoquinone-p-phenylene copolymer, which can substantially improve multiple charging The ability to maintain capacity during the cycle.
Professor Noriyoshi introduced that the battery with the new copolymer as a binder can maintain 95% of its capacity after 1700 cycles of charging and discharging, while the traditional PVDF binder (polyvinylidene fluoride, mainly used to delay the degradation of graphite in the negative electrode of the battery) is approximately After 500 cycles, only 65% of the original capacity remains.
The professor pointed out that after the technology is commercialized, it can enhance consumers’ confidence in buying expensive lithium battery products.
It is worth mentioning that the 2019 Nobel Prize in Chemistry commended three scientists including Akira Yoshino for pioneering research on lithium batteries.
