NOVELTY - Pre-embedding of lithium in positive electrode of lithium-ion battery involves making conductive liquid, adding the positive electrode active material and lithium phosphate powder with the mass ratio of (0.99-0.85):(0.01-0.15) to the conductive liquid and stirring to obtain the electrode liquid, and coating the electrode solution on the aluminum foil. USE - Pre-embedding of lithium in positive electrode of lithium-ion battery. ADVANTAGE - The method is simple, and easy, and provides lithium-ion battery using lithium pre-embedded positive electrode with excellent energy density, and reduced irreversible capacity.
