A new SiCx/TiCx electrode material has been synthesized by ball‐milling of Ti3SiC2 MAX phase. To demonstrate the possible applications for lithium‐ion batteries, the electrochemical properties of the SiCx/TiCx nanocomposite was studied. The results indicate that this new material has a higher specific capacity (170 mAh/g) than those of pure SiC (93 mAh/g), TiC (75 mAh/g), and the mixture of SiC‐TiC (122 mAh/g) at current density of 100 mA/g for 300 cycles. Furthermore, the SiCx/TiCx nanocomposite has a specific capacity of 110 mAh/g, better than those of artificial graphite (labeled: SAG−R, 26 mAh/g) and mesocarbon microbeads (labeled: MCMB, 21 mAh/g), at current density of 1 A/g for 1000 cycles. The enhancement mechanism of the SiCx/TiCx nanostructure has been discussed by the DFT calculation. Further development of this anode material may enable practical applications for long cycling and fast charge‐discharge anode in rechargeable batteries.

“…Following the activation, the actual full-cell cycling tests have been conducted within the voltage window of 1.5–4.2 V. As shown in Figure a,c, AC/CG-Li cell demonstrates a typical charge plateau of 3.7 V, which is also observed in the AC/HOG-Li cell. However, in contrast to the AC/CG-Li cell, the specific two plateaus observed with AC/HOG-Li is due to the SEI film formation (please refer to the Figure S5), which includes the reaction between residual oxygen functional groups of rGO sheets and lithium ions. − Furthermore, AC/CG-Li and AC/HOG-Li show different trends during first and second activation cycles, which can be understood based on voltage plateaus observed during half-cell activation of these electrodes as shown in Figures S5c,d. AC/HOG-Li shows much longer discharge plateau due to the side reaction that occurs between Li ions and oxygen functional groups, as well as the formation of SEI, whereas AC/CG-Li shows significantly shorter first discharge plateau due to only the formation of SEI and a very stable second discharge plateau.…”

Highly oriented rGO sponge (HOG) can be easily synthesized as an effective anode for application in high-capacity lithium ion hybrid capacitors. X-ray diffraction and morphological analyses show that successfully exfoliated rGO sponge on average consists of 4.2 graphene sheets, maintaining its three-dimensional structure with highly oriented morphology even after the thermal reduction procedure. Lithium-ion hybrid capacitors (LIC) are fabricated in this study based on a unique cell configuration which completely eliminates the predoping process of lithium ions. The full-cell LIC consisting of AC/HOG-Li configuration has resulted in remarkably high energy densities of 231.7 and 131.9 Wh kg(-1) obtained at 57 W kg(-1) and 2.8 kW kg(-1). This excellent performance is attributed to the lithium ion diffusivity related to the intercalation reaction of AC/HOG-Li which is 3.6 times higher that of AC/CG-Li. This unique cell design and configuration of LIC presented in this study using HOG as an effective anode is an unprecedented example of performance enhancement and improved energy density of LIC through successful increase in cell operation voltage window.
