Researchers at Japan’s Advanced Institute of Science and Technology have found a way to significantly extend battery life. For anyone with a smartphone, this can solve the recurring problem-since the battery will degrade over time, even if it performs well in other areas, the life of the phone will automatically be shortened. Scientists say that the main responsibility lies in the design of lithium-ion batteries, because these batteries will degrade over time to power these state-of-the-art smartphones. Researchers at the Japan Advanced Institute of Science and Technology (JAIST) are exploring ways to make these batteries have longer capacity.
Researchers led by Professor Noriyoshi Matsui have published their latest findings in the journal ACS Applied Energy Materials, which is reported by EurekaAlert. They said that the graphite anode-negative terminal that is widely used in batteries requires a binder to hold the minerals together, but the currently used polyvinylidene fluoride binder has several disadvantages that reduce its use as an ideal bonding material. s position.
Researchers are now studying a new type of adhesive made of bisimino-naphthoquinone-p-phenylene (BP) copolymer, which they believe can solve the problem of running out of juice in smartphones. They say their research may have a profound impact, because more reliable backup systems can encourage consumers to invest more money in expensive assets, such as electric vehicles, which are a substitute for their pollution.
The lead researcher explained that although the half-cell conventional PVDF binder showed only 65% of its original capacity after 500 charge-discharge cycles, the half-cell using BP copolymer as the binder still showed signs after 1700 such cycles 95% capacity retention rate. He also said that durable batteries will help those who rely on artificial organs, as well as the general population who rely heavily on smartphones, tablets and laptops.
The research involved Professor Tatsuo Kaneko, senior lecturer Rajashekar Badam, PhD student Agman Gupta and former postdoctoral researcher Aniruddha Nag.
