Capacitor Fabrication

The energy density of a hybrid supercapacitor having CoS2 against activated carbon was increased by direct lithiation of metal sulfide before capacitor fabrication. Lithiation augmented the energy density by two-fold at all current rates and also is responsible for maintaining the capacitance retention during cycling due to the non-depletion of lithium ions in the electrolyte.

Fluorinated Carbon

Lithium/fluorinated carbon (Li/CFx) batteries are the highest-energy-density primary batteries which are widely used in various field. Herein, the novel fluorinated carbon (CFx) with superior performance are made of fluorination of ketjen-black. The fluorinated ketjen-black (F-KB) as the cathode material of Li/CFx delivered a high specific capacity over 880 mAh g-1 with a discharge plateau ~3.1 V (vs. Li+/Li). The energy density over 2400 Wh kg-1 for F-KB is higher than the theoretical energy density (2180 Wh kg-1) of fluorinated graphite. F-KB can be discharged at high rate of 5C delivering a high-power density of 9710 W kg-1 with the energy density of 1610 Wh kg-1, showing good performance of rate capability.
