Which batteries are best for home solar storage?

Lithium-Sulfur Batteries: have the potential to offer higher energy density compared to traditional lithium-ion and could be attractive for home solar storage. Metal-Air Batteries: such as lithium-air batteries, have the potential to achieve very high energy densities by using oxygen from the air as a reactant.
