Hierarchically structured and ammonium-rich Prussian blue analogue materials are prepared by a one-step hydrothermal method, and show excellent lithium storage performance.
Ultrasmall Sn nanoparticles (∼5 nm) homogeneously embedded in the shell of spherical hollow carbon show enhanced lithium storage properties with high capacity and a long life.
An indole-based conjugated microporous polymer, poly(bisindolylmaleimide) (PBIM), with superior electrochemical performance as an anode material for LIBs has been obtained by FeCl3-promoted oxidative coupling polymerization.
