The search for a solution to the battery issue in smartphones, and indeed in a variety of other tech fields, has been underway. Researchers have been attempting to come up with long-term methods for producing longer-lasting battery technologies for smartphones. There have been additions to the growth to date. However, most mobile batteries, including flagship and affordable ones, lose their original capacities after a few years of use, so the problem continues. Within the first year of usage, most mobile batteries lose up to a fifth of their power.
But it appears that this is about to change, as researchers at the Japan Advanced Institute of Science and Technology (JAIST) have developed an innovative material. That allows batteries to maintain their original power (up to 95 percent) for at least five years. This increasing the battery life within the unit. Whether it be a smartphone, laptop, or even an electric car. This discovery by Japanese scientists has far-reaching consequences. The internal composition of today’s batteries causes them to fail over time with each charge. It’s been estimated that after 500 recharges, up to 40% of the battery’s power could have been lost due to the binder material’s poor performance.
Professor Noriyoshi Matsumi and his colleagues at JAIST have developed a binder material that outperforms current technology. The negative terminals of today’s batteries use a binder substance named Polyvinylidene Fluoride (PVDF), which isn’t really nice. Typical PVDF batteries lose up to 35% of their original energy after just 500 recharges. After one or two years, the battery life on smartphones degrades.
The latest binder, though, is known as Bis-imino-acenaphthenequinone-Paraphenylene (BP). Even after more than 1700 charge cycles, the binder allowed the battery to retain 95% of its power. As a result, the battery technologies will last up to five years without losing any of its original power.
According to Matsumi, the latest technologies would aid in the development of more rugged goods. He believes it also has the power to inspire people to buy more costly battery-based assets, such as electric cars.
We anticipate that smartphone manufacturers will seek collaborations with JAIST. That will lead to the adoption of the latest battery technologies in the development of more powerful and robust batteries for smartphones and other electronic devices.
