Abstract
A facile solvothermal synthesis approach for chemical composition control in ternary Bi-S-I systems is reported by simply controlling the sulfide concentration. We demonstrate the application of these bismuth-based ternary mixed-anion compounds as high capacity anode materials in rechargeable batteries. Cells utilising Bi
S
I
achieved an initial capacity value of 807 mA h g
, while those with BiSI/Bi
S
I
a value of 1087 mA h g
in lithium-ion battery systems.
