Divya, Madhusoodhanan Lathika published the artcileHighly Reversible Na-Intercalation into Graphite Recovered from Spent Li-Ion Batteries for High-Energy Na-Ion Capacitor, Computed Properties of 143-24-8, the main research area is supercapacitor graphite tetraglyme aging; Graphite; Na-ion capacitor; ether; high-temperature aging; pre-sodiation.
High-performance Na-ion capacitor (NIC) was constructed with graphite recovered from spent Li-ion batteries (LIBs) as battery-type neg. electrode and high-surface-area activated carbon as a supercapacitor component. Unlike Li-insertion into graphite, Na-insertion into graphite is extremely limited; hence, a “”solvent-co-intercalation”” mechanism was proposed for high reversibility using ether family solvents. First, the Na-insertion properties were assessed in the half-cell assembly with 0.5 M NaPF6 in tetraethylene glycol di-Me ether as an electrolyte solution and compared with the com. graphite. The NIC comprised pre-sodiated graphite as a neg. electrode and com. activated carbon as a cathode. This fascinating NIC configuration displayed the maximum energy d. of 59.93 Wh kg-1 with exceptional cyclability of 5000 cycles at ambient temperature with approx. 98% retention. Interestingly, the electrode aging process in the presence of electrolyte resulted in approx. 19% higher energy d. than the routine electrode heat treatment. Further, the electrochem. activity of the NIC at various temperatures was studied, and it was found that the graphite recovered from spent LIBs could be effectively reused towards the construction of high-performance charge storage devices with exceptional performance.
