Multishelled Ni‐Rich Li(Ni(x)Co(y)Mn(z))O(2) Hollow Fibers with Low Cation Mixing as High‐Performance Cathode Materials for Li‐Ion Batteries

A simple seaweed biomass conversion strategy is proposed to synthesize highly porous multishelled Ni‐rich Li(Ni(x)Co(y)Mn(z))O(2) hollow fibers with very low cation mixing. The low cation mixing results from the cation confinement by the novel “egg‐box” structure in the alginate template. These holl...

Sumario:A simple seaweed biomass conversion strategy is proposed to synthesize highly porous multishelled Ni‐rich Li(Ni(x)Co(y)Mn(z))O(2) hollow fibers with very low cation mixing. The low cation mixing results from the cation confinement by the novel “egg‐box” structure in the alginate template. These hollow fibers exhibit remarkable energy density, high‐rate capacity, and long‐term cycling stability when used as cathode material for Li‐ion batteries. [Image: see text]
