LFP was obtained from Gelon LIB. The elemental composition of these materials was confirmed via X-ray Fluorescence (XRF, see details below). NMC811 was purchased from Lifun Technologies. Graphite powder (BTR V-H) was purchased from Targray. All powders were processed utilising optimised processes developed in house based on supplier recommendations. Electrodes were produced via slurry mixing (Thinky ARE-250) and casting (Erichsen Coatmaster 510). In a typical mixing process, active material and carbon black (Imerys C65) powders were weighed and mixed with polyvinylidene fluoride (PVDF, Solef 5130) predissolved in NMP (8 % wt) to the desired ratio. Further NMP was added in stages to achieve the desired solid content and viscosity for coating. LFP, LMFP and blend electrodes utilised a formulation of 93:3.5:3.5 (AM:CB:PVDF) and were cast onto carbon- coated Al foil (Cambridge Energy Solutions) while NMC811 utilised 95.5:2.5:2 and was cast onto pristine Al foil (Avocet). Electrode coat weights were 135 gsm for phosphates/blend and 170 gsm for NMC811. The electrodes were dried overnight under vacuum at 120 o C.
