Biochar produced from bio-waste of cellulose-extracted kenaf residue was utilized as a conductive additive for electrodes in electric double-layer capacitors (EDLCs). The EDLC cells were assembled using electrodes with varying mixing ratios of kenaf-derived carbon (KC), and hydrocarbons-derived carbon black (CB) which had been industrially utilized as the conductive additive. Although the sole use of KC could not provide a sufficient electronic conduction in the EDLC electrodes, the combinational use of KC and CB attained a formation of stable conductive path therein. The energy density of the EDLC cell utilizing electrodes composed of KC and CB at a mixing ratio of 50:50 in mass under the use of 8 M KOH electrolytic solution and the cell voltage range of 0−1.0 V was found to be approximately equivalent to that of electrodes composed solely of CB, particularly at power densities below 100 W kg−1. Through the application of KC to the conductive electrode additive, we discovered new potential uses for kenaf residue.

The current energy density of Li-ion capacitors (LICs) is unfavorable for industrial applications, due to the asymmetrical electrochemical kinetics between the anode and cathode. Herein, the energy density of composite anode materials is increased by optimizing the mass ratio between graphite (Gr) and nano-Si to enable the solid electrolyte interface (SEI) to effectively buffer the large volume changes of Si during lithiation/delithiation. A twice-repeated prelithiation method is used to stabilize the SEI and eliminate the irreversible capacity of the composite anodes. Variation of the Gr:nano-Si mass ratio of the composite anode from 0 to 40 mass% shows that, although the LIC with a Gr:nano-Si mass ratio of 80:20 (Gr80Si20) exhibits the highest energy density (91.9 Wh kg−1), its energy density deteriorates drastically after 10 000 cycles, retaining only 34.8% of its initial energy density. Conversely, the LIC with the composite anode with a Gr:nano-Si mass ratio of 60:40 (Gr60Si40) has slightly lower energy density (87.3 Wh kg−1) but demonstrates outstanding cycling performance with energy density retention of 87.2% after 10 000 cycles. These findings highlight the potential of incorporating Gr/nano-Si composite anodes into LICs for high-energy-density industrial applications.

Li-ion capacitors (LICs), characterized by high energy and power densities, are widely regarded as promising electrochemical energy-storage devices. However, the application of these devices is limited by the poor stability of anode materials and inferior electrochemical performance owing to asymmetrical kinetics between the anode and cathode. To address these concerns, this study aimed at developing a highly stable composite anode material by tuning the mass ratio between graphite (Gr) and hard carbon (HC). When subjected to thrice-repeated deep prelithiation, the composite anode exhibited enhanced cycling performance without significant deterioration in the capacity. The incorporation of HC in the anode effectively improved the cyclability of Gr, and the thrice-repeated deep prelithiation strategy facilitated the increase in LIC capacity. The LIC using the composite anode exhibited an energy density of 48.5 Wh kg−1 at a power density of 2170 W kg−1, surpassing those of Gr (33.8 Wh kg−1 at 2030 W kg−1) and HC (35.7 Wh kg−1 at 2230 W kg−1) LICs. The enhanced LIC retained 80.5 % of its initial energy density after 10,000 cycles, a significantly higher value than those of LICs based on Gr (26.1 %) and HC (73.3 %). In summary, deep prelithiation can enhance the overall performance of LICs to achieve improved cyclability and capacity compared with its semi-shallow prelithiated counterpart. This study provides a cost-effective solution for the design of LIC anode materials with high rate and long cycling performances. © 2024 The Authors

Large-scale lithium-ion batteries (LIBs) are overtaking as power sources for electric vehicles and grid-scale energy-storage systems for renewable sources. Accordingly, large amounts of LIBs are expected to be discarded in the near future. Recycling technologies for waste LIBs, particularly for valuable rare metals (Li, Co, and Ni) used in cathode active materials, need to be developed to construct continuous LIB supply chains. Various recovery methodologies, such as pyrometallurgy, hydrometallurgy, and direct recycling, as well as their advantages, disadvantages, and technical features, are briefly introduced. We review the electrochemical performances of these cathode active materials based on recycled rare metals from LIB waste. Moreover, the physicochemical properties and electrochemical performance of the cathode active materials with impurities incorporated during recycling, which have high academic significance, are outlined. In hydrometallurgy-based LIB recycling, the complete removal of impurities in cathode active materials is not realistic for the mass and sustainable production of LIBs; thus, optimal control of the impurity levels is of significance. Meanwhile, the studies on the direct recycling of LIB showed the necessity of almost complete impurity removal and restoration of physicochemical properties in cathode active materials. This review provides a survey of the technological outlook of reusing cathode active materials from waste LIBs.

Si is utilized as the active anode material of lithium-ion capacitors (LICs) to increase their energy and power densities. The main drawback of industrial Si-based LICs is their insufficient cycling stability resulting from the limited life of Si anodes. In this study, cell design parameters required for 10,000 stable cycles were determined using inexpensive unmodified 2 μm Si particles and a polyimide binder. Three cathode-to-anode capacity ratios were investigated by varying the thickness of a Si coating layer at a constant mass of the cathode fabricated from activated carbon (AC). The thickest Si coating with a thickness of 48 μm resulted in the anode/cathode capacity ratio of 56.4, which was calculated based on the apparent Si specific capacity of 3000 mAh g-1 and AC specific capacity of 60 mAh g-1. Conversely, the thinnest Si coating with a thickness of 10 μm exhibited a capacity ratio of 14.2 and highest energy density of 97.4 Wh kg-1 at a power density of ~1 kW kg-1 during the first cycle, and the highest cycling stability corresponding to a retention of 78.3% after 30,000 cycles. Additionally, the aging behavior of the produced anodes and cathodes was examined via postmortem material characterization.
