Puckered-layer-structured germanium monosulfide for superior rechargeable Li-ion battery anodes†
Abstract
Puckered-layer-structured germanium monosulfide (GeS) and corresponding amorphous-carbon-decorated nanocomposites (GeS–C) were synthesized and used to fabricate Li-ion battery anodes which displayed remarkable reversible capacity above 1050 mA h g−1 after 100 cycles.
