The key cause of battery deterioration, according to researchers, is graphite anodes.

Researchers have discovered a way to greatly extend the life of batteries. This could fix a common issue for smartphone owners: as batteries fail over time, a phone's life is automatically shortened, even though it performs well in other areas. According to scientists, the nature of the lithium-ion batteries that power these cutting-edge smartphones is primarily to blame, as these batteries degrade over time. Researchers at the Japan Advanced Institute of Science and Technology (JAIST) are looking into ways to make these batteries last longer.

Professor Noriyoshi Matsumi and his team published their new results in the ACS Applied Energy Materials journal, according to Eureka Alert. They claim that the commonly used graphite anodes – the negative terminal – in batteries need a binder to keep the mineral together, but the existing poly (vinylidene fluoride) binder has many flaws that make it less than ideal as a binding material.

The researchers are now looking into a new form of binder made from a  (BP) copolymer, which they believe might be able to solve the problem of smartphones running out of power too quickly.

The researchers are now looking into a new form of binder made from a (BP) copolymer that they claim could solve the problem of smartphones running out of battery power too quickly. They believe their findings will have far-reaching implications because a more efficient backup system will enable customers to spend more in costly assets such as electric vehicles rather than polluting alternatives.

According to the lead researcher, a half-cell with a traditional PVDF binder retained just 65 percent of its original capacity after 500 charge-discharge cycles, while a half-cell with a BP copolymer binder retained 95 percent of its capacity after 1700 cycles. Durable batteries, he said, would benefit those who depend on artificial organs, as well as the general public, who rely heavily on smartphones, tablets, and laptops.

Senior Lecturer Rajashekar Badam, PhD student Agman Gupta, and former postdoctoral fellow Aniruddha Nag were all involved in the research.

The online world is constantly evolving, bringing more resources, users, and activity together. The number of websites registered on the “.com” domain exceeded 150,000,000 last year. However, after more than a quarter-century of commercial use, the online world's growth is now declining in several main categories.

We studied global patterns in online diversity and domination over the course of several years. Our research, which was published today in the Public Library of Science, is the first to show long-term developments in how companies perform in the digital era. We saw a drastic concentration of attention on a small (but growing) number of online organisations. As a result, while the number of entities providing these functions on the web continues to increase, the number of entities providing these functions is dwindling.
