Transition metal sulfides (TMSs) have been demonstrated as attractive anodes for potassium-ion batteries (KIBs) due to the high capacity, abundant resource, and excellent redox reversibility. Unfortunately, practical implementation of TMSs KIBs is still hindered by unsatisfactory cyclability rate performance which result from vast volume variation during charge/discharge processes. Herein, a uniform nitrogen-doped carbon coated Cu2S hollow nanocube (Cu2S@NC) designed an anode material KIB,...

Abstract The capacity attenuation and poor safety caused by lithium dendrite interface side reactions have hindered the application of lithium–metal batteries (LMBs) for a long time. To solve this problem, some liquid or salt additives been added to electrolyte promote uniform stripping/plating lithium, however, consumption during cycles reduces concentration active components, resulting in gradual failure additives. Herein, new solid additive (nano CaCO 3 ) working under principle sustained...

Rechargeable lithium batteries based on metal anodes and high-nickel cathodes have unparalleled advantages in energy density. However, the massive growth of dendrites rapid degradation ternary oxides commercial electrolyte greatly hindered their application. To circumvent this issue, we design a series analogues as additives by adopting acetyls connecting units to splice multiple functional groups. Among these additives, N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) stands out due...
