Preparation of yolk–shell urchin-like porous Co₃O₄/NiO@C microspheres with excellent lithium storage performance

Abstract

Yolk–shell urchin-like porous Co3O4/NiO@C microspheres were synthesized via solvothermal method and annealing treatment. A high reversible capacity of 502.7 mA h g−1 was maintained after 1000 cycles at 5 C, showing the long cycling stability.

Design of functional binders for high-specific-energy lithium-ion batteries: from molecular structure to electrode properties

“…Also, dispersed particles lose the pathways to transfer electrons and ions. Some strategies are proposed to ameliorate the negative effects from volume change, such as a special yolk-shell structure 113 and an elastic binder. 30 Although binders are believed to be an ideal volume buffer inside the electrode matrix, the binder itself suffers from mechanical failure.…”
