  1. CSP, Carbon Super P; LFP, LiFePO4; LMO, LiMn2O4; LTO, Li4Ti5O12; MWNT, multiwalled carbon nanotubes; PEGDME500, poly(ethylene glycol) dimethyl ether average Mn ~500; PLA, polylactic acid.
  2. *Weight-volume conversion was deduced by ourselves considering the densities obtained for analogous materials via helium pycnometer.
