Almost all electronic devices these days run on Lithium-Ion batteries. These batteries are often used in portable battery stations, electric vehicles, and other electronic devices. However, with continued use, their performance degrades rapidly. A Japanese institute has now discovered a new battery technology that can make battery health loss a thing of the past.
JAIST Battery Technology: Overview
After a couple of years, the battery health of all smartphones, including the flagships, degrades. As a result, most smartphones only have a quarter of their battery capacity as years go by. Researchers and big brands are working furiously to find a reliable alternative. A research team from Japan’s Advanced Institute of Science and Technology (JAIST) has discovered a breakthrough material that allows the battery to retain its capacity for at least five years and probably longer.
The research, led by Professor Noriyoshi Matsumi, discovers that the Li-Ion battery we use these days contains a binder substance known as Polyvinylidene Fluoride (PVDF). Binder is in charge of keeping the active material particles inside the electrode of a lithium-ion battery (LIB) together in order to maintain a strong association between the electrodes. After 500 charging cycles, the PVDF binder we use degrades, losing 35% of its charging power in this brief period of time.

The new binder material by the JAIST team, however, is known as Bis-imino-acenaphthenequinone-Paraphenylene (BP); and it can maintain 95% battery health after 1700 charge cycles. That’s 5 years of battery life without losing its almost original capacity. According to Matsumi, the production of long-lasting batteries would aid in the development of more dependable devices for long-term use. Furthermore, it will enable customers to buy costly battery-based assets such as electric vehicles, ensuring long-term efficiency.
We hope to see major companies collaborate and do more research on this subject. The newly discovered battery technology by the Japanese institute has the potential to change a long-term issue with batteries. Additionally, brand loyalty will improve, and customers will be able to enjoy reliable and durable products.
