Chinese Academy of Sciences: Significant Breakthrough in Key Technologies for Black Phosphorus Fast-Charging Batteries Opens New Technological Pathways

As the demand for ultra-fast charging and high-capacity batteries in new energy vehicles and large-scale energy storage systems continues to grow, the performance of traditional graphite anode materials has approached its theoretical limit. Recently, the team led by Ma Yanwei at the Institute of Electrical Engineering, Chinese Academy of Sciences, successfully broke through this technical bottleneck, innovatively proposing a lattice phosphorus nitrogen (P N) bond engineering strategy, achieving stable charge and discharge of black phosphorus anode materials under ultra-high rates. This has significant implications for promoting the practical application of BP-based fast-charging batteries. The team successfully fabricated a soft-pack battery with black phosphorus as the anode and lithium iron phosphate as the cathode, with an energy density of 282 Wh/kg. Under high-rate charging conditions, this battery can reach 80% of its theoretical capacity in just 10 minutes, and it can still operate stably after thousands of charge-discharge cycles, demonstrating excellent fast-charging cycle durability. This achievement opens a new technological pathway for next-generation high-energy-density, high-power energy storage devices, providing key support for the iterative upgrade of fast-charging power batteries, grid energy storage, and specialized high-rate energy storage equipment in China.
