Abstract

The present invention provides a method of reducing the charge/discharge capacity fade rate of a rechargeable lithium-ion battery (LIB) during cycling, and extending the life and the number of discharge/recharge cycles thereof, effected by coating particles of lithium intercalation materials used for making the electrodes of the LIB, with a uniform layer of a metal fluoride effected by atomic layer deposition (ALD). The present invention further provides coated particulate lithium intercalation materials, electrodes and lithium-ion batteries having electrodes made with particulate lithium intercalation materials coated with a uniform later of a metal fluoride using ALD.
