  • Hard carbon/graphite composite anode for durable lithium-ion capacitor

    Cheng Jie Chng, Xinyu Ma, Yusuke Abe, Seiji Kumagai

    Journal of Energy Storage ( ELSEVIER )  92   112913   2024.05  [Refereed]

    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

  • Cathode active materials using rare metals recovered from waste lithium-ion batteries: A review

    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.

  • Effect of Si layer thickness on the cycling stability and aging behavior of Li-ion capacitors with micrometer-sized Si anodes

    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.

  • Effects of Excessive Prelithiation on Full-Cell Performance of Li-Ion Batteries with a Hard-Carbon/Nanosized-Si Composite Anode

    The effects of excessive prelithiation on the full-cell performance of Li-ion batteries (LIBs) with a hard-carbon/nanosized-Si (HC/N-Si) composite anode were investigated; HC and N-Si simply mixed at mass ratios of 9:1 and 8:2 were analyzed. CR2032-type half- and full-cells were assembled to evaluate the electrochemical LIB anode behavior. The galvanostatic measurements of half-cell configurations revealed that the composite anode with an 8:2 HC/N-Si mass ratio exhibited a high capacity (531 mAh g−1) at 0.1 C and superior current-rate dependence (rate performance) at 0.1–10 C. To evaluate the practical LIB anode performance, the optimally performing composite anode was used in the full cell. Prior to full-cell assembly, the composite anodes were prelithiated via electrochemical Li doping at different cutoff anodic specific capacities (200–600 mAh g−1). The composite anode was paired with a LiNi0.5Co0.2Mn0.3O2 cathode to construct full-cells, the performance of which was evaluated by conducting sequential rate and cycling performance tests. Prelithiation affected only the cycling performance, without affecting the rate performance. Excellent capacity retention was observed in the full-cells with prelithiation conducted at cutoff anodic specific capacities greater than or equal to 500 mAh g−1.

  • Electrochemical performance of LiNi1/3Co1/3Mn1/3O2 cathode recovered from pyrolysis residue of waste Li-ion batteries

    Yusuke Abe, Kensuke Sawa, Masahiro Tomioka, Ryoei Watanabe, Tatsuya Yodose, Seiji Kumagai

    A methodology for time-effective, automatic, and safe extraction of cathode active materials from waste lithium-ion battery (LIB) stacks without complex mechanical disassembly and using electrically and chemically harmless processes can be beneficial for the sustainable fabrication of LIB. Herein, we present a feasibility study on the recovery of ternary Li transition metal oxide (LTMO) cathode active materials from the residue of a waste automotive LIB stack using pyrolysis at 800 °C without exposure to air. Sequential processes from pyrolysis, residue grinding, classification (sieving), wet magnetic separation, acid leaching, hydroxide precipitation, and desalination to drying were used to prepare the precursor of the cathode active material. The precursor was mixed with Li2CO3 and sintered in air at 800 °C, which yielded LiNi1/3Co1/3Mn1/3O2 (NCM) with metallic impurities of Al, Cu, and Fe at a total of 4 mass% as well as excess Li and residual F. The electrochemical performance of waste LIB-derived LiNi1/3Co1/3Mn1/3O2 (W-NCM) cathode active materials was evaluated in half-cell and full-cell configurations and compared with that of a commercial LIB cathode active material of LiNi0.5Co0.2Mn0.3O2 (NCM) used in automobile applications. The Li-ion extraction/insertion specific capacity of W-NCM in the half-cell was 120 mAh/g at 15 mA g−1, which was 70.4 % that of NCM. The specific capacity of W-NCM in a full-cell using a graphite anode at 0.1 C was 85 mAh/g, which was 69.1 % that of NCM. However, W-NCM in the full-cell exhibited much higher capacity retention (91.2 %) after 1000 charge–discharge cycles at 2 C, while the capacity retention of NCM was 34.0 %. The excellent cycling performance of W-NCM was attributed to the co-existence of metallic impurities. The proposed cathode recovery method may be further explored for applications in large-scale and automatic recycling of waste LIBs.
