A Method Of Formation Of A Secondary Battery

Abstract: ABSTRACT A METHOD OF FORMATION OF A SECONDARY BATTERY The present disclosure provides a method of formation of a secondary battery comprising a metal current collector, the method comprising: tap-charging the battery to a first potential (Va) greater than reduction potential of at least one 5 electrolyte additive to partially form a solid electrolyte interphase (SEI) layer; thermal aging the tap-charged battery to densify the solid electrolyte interphase layer; and performing consecutive charging on the aged battery to a second potential (Vb) enabling complete reduction of the electrolyte additive for the SEI layer formation; and discharging to a third potential (Vc) to obtain the battery, 10 wherein tap-charging to the first potential (Va) partially reduces the electrolyte additive. Further, the present disclosure provides a battery formed by the method as disclosed herein. 15
