“…On the other hand, a large-scale preparation of Li 3 N containing electrodes with super low cost was successfully realized via a slurry coating process using N,Ndimethylformamide (DMF) solvent, which could avoid the troublesome issue about the high reactivity of often-used solvents like N-methy-2-pyrrolidone (NMP). [121] The constructed LIC with 12 wt% Li 3 N addition in AC cathode electrode deliver excellent ultrahigh energy density of about 120 Wh kg −1 and excellent cycle stability with about 90% retention after 10 000 cycles. Similarly, sodium deficiency issue of P2-Na 0.67 [Fe 0.5 Mn 0.5 ] O 2 cathode could be addressed by the addition of NaN 3 .…”

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.

“…Well-controlled pre-lithiation could largely improve the structural stability of the electrode, enhance the reversible capacity and working voltage of the full cell and reduce the resistance, which thus increases the energy and power densities and cycling life. However, current pre-lithiation technologies such as internal or external short circuit [ 150 , 151 ] or using lithium-containing compounds [ 152 , 153 , 154 ] are either unsafe, time-consuming or inefficient. Hence, high-efficiency pre-lithiation methods are highly needed.…”

Graphene-Based Cathode Materials for Lithium-Ion Capacitors: A Review

et al. 2021

View full text Add to dashboard Cite

Lithium-ion capacitors (LICs) are attracting increasing attention because of their potential to bridge the electrochemical performance gap between batteries and supercapacitors. However, the commercial application of current LICs is still impeded by their inferior energy density, which is mainly due to the low capacity of the cathode. Therefore, tremendous efforts have been made in developing novel cathode materials with high capacity and excellent rate capability. Graphene-based nanomaterials have been recognized as one of the most promising cathodes for LICs due to their unique properties, and exciting progress has been achieved. Herein, in this review, the recent advances of graphene-based cathode materials for LICs are systematically summarized. Especially, the synthesis method, structure characterization and electrochemical performance of various graphene-based cathodes are comprehensively discussed and compared. Furthermore, their merits and limitations are also emphasized. Finally, a summary and outlook are presented to highlight some challenges of graphene-based cathode materials in the future applications of LICs.

“…% of Li 3 N in the AC electrode manufacturing process. [56] Unfortunately, the profile of the negative electrode operates too close to 0 V vs. Li + /Li (Figure 7b) at a discharge time of 200 min, what most probably will infer lithium plating at higher rates. However, energy-to-power values showing up to 50 Wh kg À 1 AM energy density output at 5000 W kg À 1 AM power density, per mass on active materials on both cathode and anode, were reported.…”

Lithium ion capacitor (LIC) is an emerging technology that holds promise to bridge the energy‐to‐power gap between already market stablished lithium ion battery and electrochemical double‐layer capacitor technologies. Academic research is mainly focused on increasing energy, power and cycle life metrics, but next, pre‐lithiation strategy is the key that will open the final door, or not, towards industrialization and commercialization of the technology. Its relevance has only recently been thoroughly considered, but several strategies, all with their own particular set of assets, are already available within the state‐of‐the‐art. It is the right moment to make a retrospective review analysis of the pros and cons of each of the strategies, in order to draw the correct conclusions and look into the future with the best perspective. Despite some reviews newly considered the topic, they were all done in a broader framework, what finally waters down the importance of this critical step. Thus, this review aims to solely focus on the pre‐lithiation strategies that have been reported so far for LICs, from the first academic auxiliary lithium metal approach to the latest novel strategies. To conclude, challenges and requierements that the ideal pre‐lithiation strategy should fulfil in order to foster market uptake of LIC technology are also discussed.
