“…For this technique, porous current collectors are required to enable lithium ion transport. The pre-lithiation method was further improved by using porous electrodes as shown by Tsuda et al [167]. Besides JMEnergy, companies like Asahi Kasei Corporation (Chiyoda, Japan) or Subaru (Shibuya, Japan) have also vigorously researched the pre-lithiation of LICs [42,161,[168][169][170].…”

Abstract:In order to meet the sophisticated demands for large-scale applications such as electro-mobility, next generation energy storage technologies require advanced electrode active materials with enhanced gravimetric and volumetric capacities to achieve increased gravimetric energy and volumetric energy densities. However, most of these materials suffer from high 1st cycle active lithium losses, e.g., caused by solid electrolyte interphase (SEI) formation, which in turn hinder their broad commercial use so far. In general, the loss of active lithium permanently decreases the available energy by the consumption of lithium from the positive electrode material. Pre-lithiation is considered as a highly appealing technique to compensate for active lithium losses and, therefore, to increase the practical energy density. Various pre-lithiation techniques have been evaluated so far, including electrochemical and chemical pre-lithiation, pre-lithiation with the help of additives or the pre-lithiation by direct contact to lithium metal. In this review article, we will give a comprehensive overview about the various concepts for pre lithiation and controversially discuss their advantages and challenges. Furthermore, we will critically discuss possible effects on the cell performance and stability and assess the techniques with regard to their possible commercial exploration.

“…Tsuda and co‐workers designed a porous electrode that can allow Li + transmit from Li metal counter electrode to the working electrode in the full cell. [ 74 ] However, extra separators and Li metal electrodes are added into the cell, resulting in lower volumetric energy/power density of LICs and higher safety risk during manufacture.…”

In contrast, EDLCs can provide high power density (≥10 kW kg −1 ), and is capable for high power system like light rail etc. [5] However, its low energy density (≤10 Wh kg −1 ) blocks its path to long period power supply. [3] Lithium-ion capacitors (LICs), as a hybrid of EDLCs and LIBs, are a promising energy storage solution capable with high power (≈10 kW kg −1 , which is comparable to EDLCs and over 10 times higher than LIBs) and high energy density (≈50 Wh kg −1 , which is at least five times higher than SCs and 25% of the stateof-art LIBs). [6] The comparison of device configurations, their charge/discharge profiles as well as performance characteristics of LIBs, EDLCs and LICs are shown in Figure 1. LIBs contain two insertion-type electrodes as positive and negative electrodes respectively, which store/output energy via Li + insertion/extraction. The plateaus are observed on charge/discharge curve while peaks can be pointed out in cyclic voltammetry curve, reflecting the insertion/extraction of cation and the redox reactions in the bulk material. With the massive cation storage in the bulk materials, LIBs demonstrate high energy density. However, the power performance of LIBs is limited by the slow ion diffusion in the bulk material, though the self-discharge rate (<5% of the stored capacity over 1 month) is suppressed. [7] With the high energy density, flammable electrolyte, and chemical reaction during charge/ discharge, safety issue is critical for LIBs application. [8] Differently, EDLCs contain two adsorption-type electrodes which adsorb/ desorb ions during charge/discharge. The easily accessible surface ion storage site permits the rapid charge/discharge capability of EDLCs. The physical change during charge/discharge and low-energy density enable the high safety of EDLCs. But the selfdischarge (≈50-80% loss in energy per day) is serious due to the poor interaction between the ion and the active material surface. [9] Taking the much lower energy density into consideration, the energy-based cost ($ kW h −1 ) of EDLCs (≈$10000 kW h −1 ) is much higher than LIBs ($100-200 kW h −1 ). [10] To combine the advantages of both LIBs and EDLCs, the first type of LICs was introduced by Amatucci et al. in 2001, which used an activated carbon cathode capturing PF 6 − via adsorption/desorption and a nanostructured Li 4 Ti 5 O 12 anode storing Li + through insertion/extraction. [11] The typical hybrid configuration of LICs, as shown in Figure 1a, contains a LIBs electrode and an EDLCs electrode with an organic lithium-ion containing electrolyte, e.g., activated carbon (AC)//graphite and AC//Li 4 Ti 5 O 12 (LTO). [12] Later, in order to improve the power density, capacitor//capacitor asymmetric LICs, like AC//AC, and AC//MXene were investigated. [13] The

“…In fact, this approach enables the technology development at industrial scale by pre-lithiating the graphite in a constructed laminated cell, which is key in the fabrication of LICs. [30] To that aim, the pre-lithiation plate is used (see Figure 2b), which is coated with metallic lithium that diffuses through the graphite in the first charge. The pre-lithiation plate can be observed in detail by SEM in Figure S4, Supporting Information.…”

development of high energy electrochemical capacitors-also known by the product names of supercapacitors (SCs) and ultracapacitors (UCs)-in the mid 90's, set the technology in the EES scenario in early 2000s, with a boom of companies that started to place different products in the market. [1][2][3][4][5][6][7] However, the non-compliance of market expectations by the end of 2010 together with the consequences of a global financial crisis led to a turbulent period with a redeployment of the main characters. [8] Fortunately, it seems that the UC business is now solid, with great market expectations in key economic sectors such as transportation, renewables, or electronics (see Figure 1a). Parallel to industry, academic research in the field experienced a rapid growth as indicated by the steady increase in the number of annual publications (see Figure 1b). In the first period of the century, the growth was contended, and there were several reports devoted to the metrics and the proper characterization of materials and devices given the evolution of the learning curve. [9][10][11][12] 2010 became a turning point, when the chaos generated in literature by the many novel materials and architectures rising without a universally accepted definition, tremendously difficult to track technology progress. That same year, Conte proposed the actual naming criterion in order to organize the field. [13] Soon after, the community experienced an over-rapid growth which required several tutorials in order to "refresh" best practices for measuring and reporting metrics such as capacitance, capacity, coulombic and energy efficiencies, electrochemical impedance, and energy and power densities of faradaic, capacitive and pseudocapacitive materials for SCs. Prof. Simon and Prof. Gogotsi started a cycle of guidance articles in 2011 who themselves closed in 2019, [14,15] with many more parallel guidelines been published during those years, [16][17][18] and still seem not to be enough further in 2020. [19] Research in UCs has been driven by the dire need of increasing energy density, the final judge, even for most highpower applications. In 2001, a novel technology emerged to complete the current EES systems trio. Lithium-ion capacitors (LICs) were born in order to fill the energy gap between lithium-ion batteries (LIBs) and UCs [20,21] (Figure 1c). LICs are combining both LIB and UC characteristics and are risingThe fast growth experienced by the field of lithium-ion capacitors (LICs) in the last five years led to tremendous progress in this technology. However, the authors have observed some parallelism with its ultracapacitor (UC) sister technology, where an over-rapid growth in the last decade resulted in a loss of focus and the need of several tutorials for reconducting incorrect reporting habits. In the light of what may be coming, the authors aim to set this work as a direction to the scientific community and the new researchers in the field to serve as i) a retrospective analysis of the original target for LICs to prevent focus dev...
