Abstract: A LiS battery includes a heterostructure deposited on a sponge of carbon nanotubes followed by annealing. The heterostructure may be performed by depositing layers of TiN and TiO2, such as TiN followed by TiO2. Following annealing, the TIN and TiO2 may be distributed substantially uniformly in the heterostructure. In some embodiments, the TiN layer has a thickness of 10 nm and the TiO2 layer has a thickness of 5 nm.
