Tóm tắt

The low specific capacity and the poor capacity retention at extreme fast charging/discharging limit the nickel-rich layered cathode commercialization in electric vehicles, and the root causes are interface instability and capacity loss induced by birth defects and irreversible phase transition. In this work, we propose a lattice reconstruction strategy combining polyvinylpyrrolidone-assisted wet chemistry and calcination to prepare the aluminum-modified LiNi
