On April 23, it was reported that the burgeoning fields of new energy vehicles and large-scale energy storage systems are in dire need of ultra-fast charging and high-capacity batteries. Traditional batteries, relying on graphite anode materials, are nearing the peak of their performance capabilities. Recently, the team helmed by Ma Yanwei from the Institute of Electrical Engineering at the Chinese Academy of Sciences has creatively introduced a lattice phosphorus-nitrogen (P-N) bond engineering strategy. This innovative approach enables black phosphorus anode materials to maintain stable charging and discharging at ultra-high rates, marking a significant milestone in advancing the application of black phosphorus-based fast-charging batteries.

The team successfully fabricated a pouch cell, utilizing black phosphorus as the anode and lithium iron phosphate as the cathode, achieving an impressive energy density of 282 watt-hours per kilogram. When subjected to high-rate charging, the battery can attain 80% of its theoretical capacity within a mere 10 minutes. Moreover, it exhibits remarkable stability even after thousands of charge-discharge cycles, showcasing exceptional fast-charging cycle durability.

This groundbreaking achievement not only opens up a novel avenue for the next generation of high-energy-density and high-power energy storage devices but also provides pivotal support for the enhancement of fast-charging power batteries, grid energy storage, and specialized high-rate energy storage equipment in China.
