This anode material may help to offer long life of lithium batteries, aid ultra-fast charging

This anode material can help ensure the long life of lithium batteries by facilitating ultra-fast charging

You’ll soon be able to super-fast charge your battery-based gadgets or even electric vehicles as a team of researchers from Indian Institute of TechnologyGandhinagar (IITGN) and Japan Advanced Institute of Science and Technology (JAIST) has invented a new anode material that allows lithium batteries should charge within minutes. According to the team, the new two-dimensional (2D) anode material was developed using nanosheets derived from titanium diboride (TiB2), a material that resembles a stacked sandwich with metal atoms sandwiched between layers of boron.

“What makes this work particularly useful is the fact that the method for synthesizing TiB2 nanosheets is inherently scalable. It only requires mixing TiB2 particles in a dilute aqueous solution of hydrogen peroxide and allowing it to recrystallize. For any nanomaterial to turn into a tangible material, scalability is the limiting factor in the technology.

“Our method to synthesize these TiB2 nanosheets only requires stirring and no complicated equipment, so it is very suitable,” said. Kabeer YasuyaDr. Dinesh O Shah Chair Associate Professor Chemical Engineering IITGN.

The research teams at IITGN and JAIST aimed to develop a material for the anode that not only provides fast charging from a battery but also facilitates its long service life.

“This transformative research innovation has rich potential for translation from the laboratory to real-life applications. Currently, graphite and lithium titanate are among the most widely used anode materials in commercially available lithium-ion batteries (LIBs) that power laptops, cell phones, and electric vehicles. LIB a graphite anode, which is extremely energy dense, can power an electric vehicle for hundreds of kilometers in a single charge cycle. Yasuya said.

“However, they have their share of safety challenges due to the risk of fire. Lithium titanate anodes are safer and more desirable alternatives, and they also facilitate rapid charging. However, they have a lower energy density, which means they would require more frequent charging, he added.

The team also had another consideration: the material must be such that it can be synthesized in a simple, scalable way, so that it can transform existing technologies.

The researchers believe this is a promising technology for commercial applications where high energy density, high power, long lifetime and ultra-fast charging are desired. The research team plans to translate this work from the laboratory to real life.

“Today, the demands for high-speed charge-discharge technology are increasing tremendously to ensure the commercialization of a wide variety of electric vehicles in the future. Our findings can stimulate related research fields to invite more researchers to work on the application of electric vehicles. Unique 2D materials.

“We hope that continued research will contribute to the convenience of EV users, less air pollution on roads, especially in cities, and a less stressful, mobile life that will improve society’s productivity,” said Noriyoshi MatsumiJAIST Professor of Materials Chemistry.
