Pre-lithiation design and lithium ion intercalation plateaus utilization of mesocarbon microbeads anode for lithium-ion capacitors

“…Tu et al reported the electrochemical performance of porous graphene as cathode active material. It was found that the porous graphene could be a very promising candidate as electrode material of LIC with high energy/ power density [20]. Stoller [22].…”

Cycle performance of lithium-ion capacitors using graphite negative electrodes at different pre-lithiation levels

“…Aida et al proposed the production of HF at the AC PE when the potential was >4 V vs. Li/Li + [25]. HF formation was attributed to the reaction between PF 6 -and H + derived from residual moisture in the AC. The generated HF could move to the carbon NE and induce the formation of LiF as a porous SEI layer.…”

“…One reason for using porous activated carbon for the PE is its high specific surface area to absorb and desorb a number of counterpart anions of Li + , such as PF 6 À . Well-established materials for the NEs of LICs are graphite [3][4][5][6][7][8], amorphous carbon [9][10][11], and polyacene [12]. The effects of carbon types in the NEs on the electrochemical performance of LICs have been extensively investigated [13][14][15][16].…”

A High Performance Lithium-Ion Capacitor with Both Electrodes Prepared from Sri Lanka Graphite Ore

“…Analogously, three dimensional porous graphene macroform were coupled with anode of Li 4 T 5 O 12 to fabricate a hybrid capacitor which delivers a maximum energy density of 72 W·h·kg −1 at 650 W·kg −1 , and 40 W·h·kg −1 at a high power density of 8.3 kW·kg −1 [24]. The ethylene glycol assisted-hydrothermally reduced graphene delivered a superior power density used as cathode material for the LICs [25]. Based on the above results, we infer that the design of cathode materials is of great importance in achieving a high-power performance of the LICs.…”
