In a recent paper, the CSP was extended to tape-casted cathode materials, as displayed in Fig. 6 [102]. The sintered electrode was composed of LiFePO4 and carbon nano-fibers, with no additional binder. A high density of 2.42 g/cm3 was achieved, corresponding to a relative density of 70%, which was much higher than conventional tape-casted LiFePO4 electrodes (1.9 g/cm3 ).
