“…When electrochemical tests were carried out using a three‐electrode configuration with propylene carbonate (PC) as the electrolyte, metallic lithium as the reference electrode, and AC, graphite, and hard carbon (HC) as the anode electrodes in LICs, Yuan et al found that the LICs of AC/HC had better rate capability and higher capacity. In the charge–discharge process, compared with spherical HC, irregular HC showed a distinct lithium‐ion intercalation plateau.…”

Among the various energy-storage systems, lithium-ion capacitors (LICs) are receiving intensive attention due to their high energy density, high power density, long lifetime, and good stability. As a hybrid of lithium-ion batteries and supercapacitors, LICs are composed of a battery-type electrode and a capacitor-type electrode and can potentially combine the advantages of the high energy density of batteries and the large power density of capacitors. Here, the working principle of LICs is discussed, and the recent advances in LIC electrode materials, particularly activated carbon and lithium titanate, as well as in electrolyte development are reviewed. The charge-storage mechanisms for intercalative pseudocapacitive behavior, battery behavior, and conventional pseudocapacitive behavior are classified and compared. Finally, the prospects and challenges associated with LICs are discussed. The overall aim is to provide deep insights into the LIC field for continuing research and development of second-generation energy-storage technologies.

“…The class of supercapacitors known as electrochemical double layer capacitors (EDLC) use porous, high surface area, carbon electrodes immersed in a liquid electrolyte to achieve charge separation resulting in high capacitance and high power density, but with lower energy density than lithium-ion batteries [4]. To achieve higher energy densities and yet still maintain high power density, lithium-ion capacitors (LIC) have been developed which aim to bridge the gap between batteries and supercapacitors [5][6][7][8][9]. During charging and discharging of an LIC, lithium ions intercalate in and out of a graphite negative electrode, while anions adsorb and desorb to and from the surface of the positive electrode.…”

12In recent years, an increased attention has been focused on Li-ion capacitors (LICs) which are high power hybrid devices. Various carbon materials (hard carbon (HC), soft carbon (SC) and graphite) have been investigated for use as the negative electrodes for LICs. The rate capabilities are compared by half cells with carbon anode as working electrode and lithium foil as counter electrode, and by LIC full cells with test current density up to 20 mA cm −2 . It is found that the LIC with HC and SC at 20 mA cm −2 can be maintained up to 72.5% and 70%, compared to that at 0.5 mA cm −2 , which is better power performance than the graphite materials. LICs with both HC and SC as anodes displayed better cycle lifes than graphite anode. After 100,000 high-rate charge-discharge cycles, the capacity retention of the LIC with HC anode maintained higher than 85%. The Scanning electron microscopy (SEM) images, surface area and the pore size distribution are also studied and compared for the various carbon anode materials. 13 14 15 16 17 18 19 20 The hybrid energy storage devices Li-ion capacitors (LICs), which 25 are realized by combining a Li-ion batteries (LIBs) anode electrode 26 with an Electric Double-Layer Capacitors (EDLCs) cathode electrode, 27 have attracted tremendous research interests in the past a few years. 28 Extensive research has been done to realize the LICs with higher power 29 density, energy density and longer cycle life. 1-24 The characteristics 30 of LIB anode material will govern the power density and cycle life of 31 LICs compared to EDLCs. Among all the LIB anodes utilized in LICs, 32 carbonaceous-based electrodes are preferred because systems contain-33 ing carbonaceous materials show higher cell voltage and higher en-34 ergy density although they come along with the formation of the solid 35 electrolyte interphase (SEI) on the surface of the negative electrodes. 25 36 Therefore, the carbon is a promising material as negative electrode 37 for LICs. In LIBs, a wide variety of carbons were produced and used 38 as negative electrode of LIBs for investigation. The carbon materials 39 for LIBs can be classified into three different types, non-graphitizable 40 carbon (hard carbon, (HC)), graphitizable carbon (soft carbon, (SC)) 41 and graphite. The graphite is usually graphitized at a temperature ca. 42 2500 • C and has high crystallinities. In general, these graphites dis-43 play the properties of excellent cycle performance, high capacities 44 of 350-370 mAh g −1 , and coulombic efficiencies higher than 90%. 45 The SC, which is heat-treated between ca. 1100 and 2500 • C, shows 46 excellent characteristics in terms of high-rate charge/discharge per-47 formance and cyclability. 26 The HC is heat-treated at 1000-1100 • C 48 and shows a higher capacity than 372 mAh g −1 . The HC has re-49 cently received much attention as the negative electrodes for the 50 large scale LIBs for hybrid electric vehicles (HEVs), because it 51 has the characteristics of excellent cyclability and high input/output 52 performance...
