Nitrogen-doped carbon decorated 3D NiCoSe₂ micro-flowers as high-performance anode materials for lithium-ion batteries

Abstract

NiCoSe2 composited Nitrogen-doped carbon (NiCoSe2/NC-700, NiCoSe2/NC-800, and NiCoSe2/NC-900) with microflower structure were synthesized by calcining nickel-cobalt bimetallic organic skeleton materials at different temperatures, which were used as anode materials for...

Driving the rapid regeneration of LiFePO4 from spent lithium-ion batteries through one-pot mechanochemical activation

“…Owing to its high electrochemical activity, oxidation–reduction potential, and specific heat capacity, lithium is considered to be the critical factor to promote the revolution of modern electric devices. 1–3 Lithium-ion batteries (LIBs) play an essential role in this electrification revolution and promotes technological innovations as the major electrochemical power source. 4–8 Among them, owing to their structural stability, in particular, a better safety, lithium iron phosphate (LiFePO 4 , LFP) batteries have been the prime focus for lithium-ion battery manufacturers.…”
