(a) First charge (—) and discharge () obtained at a constant current of C/24 between 2 and 4 V versus graphite in an LFP/graphite battery. A paper Kodoshi separator is used, and an excess of the anode capacity is employed. (b) The corresponding long cycling experiment is performed at a 1 C rate. The full and empty characters represent the Coulombic efficiency (%) and discharge capacity, respectively.
