“…[140][141][142][143] Thus, a unique approach based on sacrificial organic salts has been explored. [144,145] Notably, the sacrificial organic salts possess the merits of abundant resources, low cost, and environmental friendliness, which is beneficial for promoting commercialized application. A lithiated material, namely 3,4-dihydroxybenzonitrile dilithium salt (Li 2 DHBN), can irreversibly provide lithium cations to the anode during an initial operando charging step without any negative effects in LIC system (Figure 12a).…”

Prelithiation/presodiation techniques are regarded as indispensable procedures in electrochemical energy storage (EES) systems, which can effectively compensate irreversible capacity loss, raise working voltage, and increase Li+/Na+ concentration in the electrolyte. Various prelithiation/presodiation methods have been successfully exploited and a revolutionary impact has been achieved through the utilization of prelithiation/presodiation techniques. It is well acknowledged that different prelithiation/presodiation strategies possess their own specific mechanisms, which play vital roles in the advancement of EES systems. However, there has rarely been systematical reviews about the concept and progress of prelithiation/presodiation techniques. Hence, in this review various prelithiation/presodiation approaches are comprehensively analyzed and summarized, and in‐depth prelithiation/presodiation behaviors and other innovative applications (including optimization of separators, amelioration of binders, regeneration of spent batteries) are discussed in detail. Finally, suggested future directions of prelithiation/presodiation techniques are proposed and it is expected that these prelithiation/presodiation techniques could provide guidance for construction of advanced EES systems and propel the commercialization process with a focus on safety considerations.

“…For positive electrode materials, the specific capacitance can be significantly increased through the following strategies: adopting capacitive materials with appropriate pore size and high specific surface area, introducing other elements, and developing other porous carbon from biomass or polymer precursors. It is also important to explore new strategies for pre‐potassiation to work as a secondary potassium source to compensate the initial potassium loss and improve the CE [143–145] . The electrolyte is a key component to determine the overall energy density of KICs.…”

As a new type of capacitor–battery hybrid energy storage device, metal‐ion capacitors have attracted widespread attention because of their high‐power density while ensuring energy density and long lifespan. Potassium‐ion capacitors (KICs) featuring the merits of abundant potassium resources, lower standard electrode potential, and low cost have been considered as potential alternatives to lithium‐/sodium‐ion capacitors. However, KICs still face issues including unsatisfactory reaction kinetics, low energy density, and poor lifetime owing to the large radius of the potassium ion. In this Review, the importance of emerging potassium‐ion capacitor is addressed. The Review offers a brief discussion of the fundamental working principle of KICs, along with an overview of recent advances and achievements of a variety of electrode materials for dual carbon and non‐dual carbon KICs. Furthermore, electrolyte chemistry, binders as well as electrode/electrolyte interface, are summarized. Finally, existing challenges and perspectives on further development of KICs are also presented.

“…The following can be performed using distinctive pre-lithiation approaches [13,30,45,63]: the electrochemical process (ECP); the short-circuit prelithiation through external short-circuit (ESC) and internal short-circuit (ISC) methods; the introduction of permanent lithium transition metal oxides (LTMOs) on the cathode side; and, the application of sacrificial lithium chloride to the electrolyte. Pre-lithiation methods can also be adapted between different capacitor chemistries (e.g., LIC, NIC and KIC) [123]. Jin et al (2020) give a thorough review of pre-lithiation technologies in LICs, outlining the current progress and perspectives [124].…”

Lithium-ion capacitors (LICs) have gained significant attention in recent years for their increased energy density without altering their power density. LICs achieve higher capacitance than traditional supercapacitors due to their hybrid battery electrode and subsequent higher voltage. This is due to the asymmetric action of LICs, which serves as an enhancer of traditional supercapacitors. This culminates in the potential for pollution-free, long-lasting, and efficient energy-storing that is required to realise a renewable energy future. This review article offers an analysis of recent progress in the production of LIC electrode active materials, requirements and performance. In-situ hybridisation and ex-situ recombination of composite materials comprising a wide variety of active constituents is also addressed. The possible challenges and opportunities for future research based on LICs in energy applications are also discussed.
