Overview

As part of ATMANIRBHAR BHARAT for electric mobility, ARCI has developed an innovative and low-cost technology for the production of in-situ carbon modified Lithium Iron Phosphate (C-LFP) as a cathode material for Lithium-ion batteries. The technology was demonstrated on large scale (10 Kg/batch) successfully in collaboration with an Indian Powder Metallurgy Industry under public private partnership. The electrochemical performance of large scale synthesized C-LFP exhibits a capacity of 1.75 and 1.45 Ah at formation and 1C current rate respectively. ARCI has filed a patent application (202011056608) in India on 28th December 2020 and subsequently filed a PCT Application (PCT/IN2021/051138) on 6th December 2021. The Indian patent application now stands granted with the number 412586 dated 28th November 2022.  The technology is already transferred to M/s. Allox Minerals Pvt. Ltd., Hyderabad on non-exclusive basis in India and is ready for transfer to other industries.
