“…Although many material combinations are possible for the assembly of LIC, the use of activated carbon positive electrode together with lithium intercalation negative electrode appear the most convenient till now [23][24][25]. In LIC, the negative electrode materials that can be doped with lithium ion typically include Li 4 Ti 5 O 12 [26], graphite [17,27], soft carbon [10,28], and hard carbon [29][30][31]. Among these materials, graphite was an attractive negative electrode material for LIC due to its high theoretical capacity, low and stable charge-discharge plateau, natural abundance and relative low cost.…”

“…HECs are generally composed of a battery-type Faradaic anode as energy source and a capacitor-type cathode as power source, which can enhance the energy and power capabilities. A particular sample is lithium-ion capacitors (LICs), which combine Li-alloying anodes with supercapacitor cathodes (Cao et al, 2014(Cao et al, , 2015. But LICs suffer from high cost of lithium because of the scarcity in earth crust.…”

An aqueous metal ion capacitor comprising of a zinc anode, oxidized carbon nanotubes (oCNTs) cathode, and a zinc sulfate electrolyte is reported. Since the shuttling cation is Zn 2+ , this typical metal ion capacitor is named as zinc-ion capacitor (ZIC). The ZIC integrates the divalent zinc stripping/plating chemistry with the surface-enabled pseudocapacitive cation adsorption/desorption on oCNTs. The surface chemistry and crystallographic structure of oCNTs were extensively characterized by combining X-ray photoelectron spectroscopy, Fourier-transformed infrared spectroscopy, Raman spectroscopy, and X-ray powder diffraction. The function of the surface oxygen groups in surface cation storage was elucidated by a series of electrochemical measurement and the surface-enabled ZIC showed better performance than the ZIC with an un-oxidized CNT cathode. The reaction mechanism at the oCNT cathode involves the additional reversible Faradaic process, while the CNTs merely show electric double layer capacitive behavior involving a non-Faradaic process. The aqueous hybrid ZIC comprising the oCNT cathode exhibited a specific capacitance of 20 mF cm −2 (corresponding to 53 F g −1 ) in the range of 0-1.8 V at 10 mV s −1 and a stable cycling performance up to 5000 cycles.

“…Yoshino et al proposed a LIC device with an activated carbon positive electrode and a pre-lithiated carbonaceous negative electrode, which possesses superior rate capability, high energy density, and long cycle life [7]. In these systems, lithium ion is intercalated into and de-intercalated from anode (Faradaic process), and anion such as PF 6 − is adsorbed and desorbed at the surface of the activated carbon cathode (non-Faradaic process) [8][9][10][11][12][13][14]. Furthermore, many research efforts were dedicated to the lithium-ion hybrid energy storage devices containing at least one bifunctional electrode including both capacitive material and lithium-ion intercalation material [2,3,[15][16][17][18][19][20].…”

Li-ion hybrid capacitor (LIC) is a type of energy storage device that bridge the gap between Li-ion battery and electrical double-layer capacitor. In the present work, LICs are assembled with activated carbon-based cathode and prelithiated hard carbon anode. The effect of temperature on the electrochemical properties of LIC is investigated by galvanostatic charge-discharge tests and electrochemical impedance analyses. The performances of LIC cells with different anode pre-lithiation degree and different cathode composition are comparatively studied. As the temperature decreases, the cell capacity decreases accordingly. The ambient temperature varies from −40 to +60°C, and the working voltage window is 1.5-4.0 V. At the temperature of −20 and −40°C, LIC cell can remain 77.7 and 33.8 % of the initial capacity at +25°C, respectively. Some approaches to improving the lowtemperature electrochemical performances of LIC have been proposed.
