Enhanced electrochemical performance of Bi2O3 via facile synthesis as anode material for ultra-long cycle lifespan lithium-ion batteries

Year: 2023

Type: article

Abstract: The urgent demand for stable electrode materials, especially for the anode, arises in the pursuit of high-energy Li-ion batteries. This research focuses on bismuth oxide (Bi2O3) and uncovers its performance through a straightforward, commercially viable synthesis route, along with the optimization of binders and electrolytes. By employing a sodium carboxymethyl cellulose binder and fluoroethylene carbonate additives, the Bi2O3 anode demonstrates significantly enhanced performance compared to prior studies. It attains an impressive initial capacity of approximately 750 mAh g-1, exhibits excellent rate capability at 1000 mA g-1 and maintains stable cycling performance over 6000 cycles.
