Carbon-coated LiFePO4 (LFP) powder, Super P conducFve carbon black, and carboxymethyl cellulose were purchased from a commercial supplier AOT Baaery, China. The materials were used for the preparaFon of cathode slurry as delivered. The cathode slurry was prepared by mixing LiFePO4 powder, Super P conducFve carbon black and 2 wt% carboxymethyl cellulose aqueous soluFon in wt% 85, 10 and 5, respecFvely. The slurry was mixed in centrifugal mixer (Thinky Mixer ARE-250, USA) at 2000 rpm for 10 minutes followed by defoaming at 400 rpm for 1 minute. The mixing procedure was then repeated again. Screen prinFng of the cathode slurry was carried out on 16 μm thick Al foil (AOT Baaery, China) by doctor blade. The thickness of the coaFng was set to 50 μm and applied at 60 °C with a coaFng speed of 5 mm/s. The coaFngs were then dried overnight in an oven at 140 °C. Calendering of the coaFngs was carried out at 30 °C (MTI MSKH-RP-1A, China). The coaFngs were cut into 14 mm diameter disc using a disc puncher (AOT Baaery, China) to serve as cathodes in coin cells. The cathodes were weighed prior to assembly to calculate specific capacity. A 9 μm thick copper foil (AOT Baaery China) was cut with the disc puncher into 15 mm diameter discs that served as anodes. Polyester/Al-oxide sheet (Freudenberg Performance Materials) was cut into a 16 mm diameter disc that served as the separator. The prepared electrodes and separator were dried overnight 80 °C in an oven.
