A team led by Ma Yanwei at the Institute of Electrical Engineering of the Chinese Academy of Sciences has recently overcome the performance bottleneck of traditional graphite-anode batteries. The team proposed a lattice phosphorus-nitrogen (PN) bond engineering strategy, enabling black phosphorus anode materials to achieve stable charging and discharging at ultra-high rates, a development of major significance for advancing the practical application of BP-based fast-charging batteries. Under high-rate charging conditions, a pouch cell developed by the team using black phosphorus as the anode and lithium iron phosphate as the cathode can reach 80% of its theoretical capacity in just 10 minutes. This achievement opens up a new technical path for the next generation of high-energy-density and high-power energy storage devices. Auto-translated by AI AASTOCKS Financial News |
