摘要： Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

摘要： An anode for a zinc metal battery and a zinc metal battery using the same are provided. An anode for a zinc metal battery includes a zinc metal film and a protective layer formed on a surface of the zinc metal film, and the protective layer may be zinc phosphate. Since the protective layer coats the outermost surface of the zinc metal film, direct contact of the zinc metal film with an electrolyte can be prevented. Accordingly, zinc dendrites formed during plating/stripping of zinc ions during charging and discharging of the battery may grow uniformly, and thus, short circuit of the battery may be prevented.
