Synthesis and investigation of layered GeS as a promising large capacity anode with low voltage and high efficiency in full-cell Li-ion batteries

Layered GeS shows a large capacity of 1768 mA h g ⁻¹ with a coulombic efficiency of 94% for lithium storage. With good stability and a low voltage in alloying region, the LiCoO ₂ //GeS full cell exhibits both high cell voltage and large capacity.
