Eco-friendly and cheap lithium ion battery electrode processing using a seaweed-derived mesoporous carbon additive (Starbon (R) A800) and binder (sodium alginate) was elaborated for LiMn2O4 (LMO) and LiNi1/3Mn1/3Co1/3O2 (NMC) lithium ion batteries. Compared to electrodes made using conventional formulations (i.e. Super P/PVDF) the 'green' electrodes can provide significantly 'upgraded' reversible capacity, almost reaching their theoretical capacity at low C-rate, likely due to good accessibility of lithium ions via the mesopores of the carbon additive. In addition, a synergistic effect was observed for a binary carbon additive system composed of Starbon (R) A800 with conventional carbon black (Super P), improving both the initial capacity and the rate capability of LMO and NMC electrodes.
