Cycling performance of Li/SeS 2 ?C, Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6 However, both Li/S and Li/O 2. systems suffer from cycling performance issues that impede their commercial applications: Li/O 2. C) and metallic Li and Na. C, Na/SeS 2 ?C,
