We would like to propose a muSR experiment on Li intercalated graphite, which is most commonly used for an anode material of Li-ion battery. With charging (discharging) reaction, Li is intercalated into (deintercalated from) graphite. In fully charged Li intercalated graphite, i.e., C6Li, Li locates between neighboring two sheets of graphene. This stracture is called Stage 1. C12Li has a stracture called Stage 2, where there are two layers of graphene between Li layer. In Li intercalated graphite CxLi with 6
