JAIST anode material may improve battery charge time and durability

Scientists at the Japan Advanced Institute of Science and Technology—a graduate school and research university—have developed a new carbon-based anode material that may increase the durability of batteries and shorten charging times.

The scientists calcinated a polymer called polybenzimidazole at 800 degrees Celsius to construct a carbon-based anode with 17 percent nitrogen, then tested it. The scientists compared graphite anodes to their anode in an article published in Chemical Communications, and say their anode retained more capacity—90 percent after 3000 cycles.

“The extremely fast charging rate with the anode material we prepared could make it suitable for use in EVs,” said lead scientist Professor Matsumi.
