Researchers at the Japan Advanced Institute of Science and Technology have found a way to dramatically increase battery life. This could solve a common problem for anyone with a smartphone – as batteries degrade over time, a phone’s lifespan is automatically reduced, even if it performs well in other ways. Scientists say the main responsibility lies in the design of the lithium-ion batteries that power these state-of-the-art smartphones, as these batteries degrade over time. Researchers at the Japan Advanced Institute of Science and Technology (JAIST) are looking for ways to give these batteries a longer capacity.

The researchers, led by Professor Noriyoshi Matsumi, published their latest findings in the journal ACS Applied Energy Materials, reported by EurekaAlert. They say the widely used graphite anodes – the negative terminal – in a battery require a binder to hold the mineral together, but the poly (vinylidene fluoride) binder currently in use has several drawbacks that reduce its position as a binding material. ideal.

Researchers are currently studying a new type of binder made from a bis-imino-acenaphthenequinone-paraphenylene (BP) copolymer, which they believe could solve the problem of smartphones running out of juice so quickly. They said their research could have far-reaching consequences, as a more reliable back-up system can encourage consumers to invest more in expensive assets such as electric vehicles than their polluting alternatives.

The principal investigator explained that while a conventional half-cell PVDF binder exhibited only 65% ​​of its original capacity after 500 charge-discharge cycles, the half-cell using BP copolymer as a binder exhibited capacity retention of 95% after 1700 of these cycles. He also said that sustainable batteries would help those who depend on artificial organs, in addition to the general population who rely heavily on smartphones, tablets and laptops.
