LixCoO2 crystallizes in α-NaFeO2 layered structure with trigonal R-3m symmetry. LixCoO2 is the general formula for cathode material for lithium-ion batteries which indicates different amounts of lithium content as Li is deintercalated from LiCoO2. LixCoO2 is a lithium-doped deficient variant of the chemical LiCoO2. The formula's 'x' stands for the variable number of lithium ions that is inserted into the substance's crystal lattice.
