Fabrication and lithium electrochemistry of InSe thin film

▶ InSe thin film has been successfully fabricated by pulsed-laser deposition method. ▶ The reversible capacity of InSe electrode of 410 mAh/g with the volumetric capacity of about 3302 mAh/cm3 was achieved. ▶ Both alloying/de-alloying processes and selenidation/reduction processes were revealed. ▶ InSe was found to be a novel candidate of anode materials for rechargeable lithium batteries.
