Scalable synthesis of hydroxyl-functionalized boron nanosheets for high ion-conductive solid-state electrolyte applications.

A hydroxyl-functionalized boron nanosheet is developed as the filler material for the solid-state electrolyte (SSE) of lithium batteries. The nanosheet exhibits good oxidation resistance and thermal stability. Its composite SSE shows high ionic conductivity, and the resulting batteries present much enhanced capacities, rate capability and cycling performance, proving the electrochemical advances of the boron nanosheet.

A solvent decomposition and explosion approach for boron nanoplate synthesis.

A new approach was applied to synthesize boron nanoplates based on layer exfoliation of etched MgB2 particles through a controlled decomposition and explosion of a widely used dipolar aprotic solvent: dimethyl sulfoxide (DMSO). These nanoplates are environmentally stable, surface-functionalized, and reveal excellent electrochemical performance as an anode material for lithium-ion batteries.
