Abstract

The cold sintering process (CSP) is an attractive method for densifying ceramic-based materials by using a transient aqueous solution at low temperature under high pressure. CSP was applied to increase the volumetric capacity density of lithium iron phosphate (LiFePO₄, LFP) based cathodes by densifying the cathode structure directly formed on a current collector. The binderless LFP cathode had a density of ~ 2.42 g/cm³ and was capable of being cycled even at the high current rate of 10C. The gravimetric and volumetric capacity of the cold sintered LFP at 10C were ~ 102 mAh/g and 247 mAh/cm³, respectively.
