“…In the first cathodic sweep, a cathodic peak around 0.6 V is ascribed to the lithiation of Sb at the beginning and the subsequent decomposition of the electrolyte to form solid electrolyte interphase (SEI) film, which is in according with the report by H.L. Lv [23]. It doesn't appear in the second cycle, reflecting the stable property of SEI film in the first cycle.…”

A simple and inexpensive route is developed to synthesis the Sb thin film sandwiched between the reduced graphene oxide and the Ni foam (RGO-SbTF-Ni) by a galvanic replacement reaction along with a pulse electrophoretic deposition route. As a binder-free anode material for lithium ion batteries, the RGO-SbTF-Ni exhibits a high initial discharge capacity of 872.9 mAh g -1 and an enhanced coulombic efficiency of 66.0% at a current density of 100 mA g -1 in the first cycle. In addition, a substantial discharge capacity of 424.1 mAh g -1 can be retained even after 50 repeated cycles. The enhanced performances of the designed binder-free anode material can be attributed to the novel hierarchical sandwich laminated structure with an excellent electrical contact, and the synergistic effect between the Sb thin film with high specific capacity and flexible RGO with good buffer effect to alleviate the strain caused by the large volume change.

A composite organic cathode material based on aromatic polyimide (PI) and highly conductive graphene was prepared through a facile in situ polymerization method for application in lithium-ion batteries. The in situ polymerization generated intimate contact between PI and electronically conductive graphene, resulting in conductive composites with highly reversible redox reactions and good structure stability. The synergistic effect between PI and graphene enabled not only a high reversible capacity of 232.6 mAh g at a charge-discharge rate of C/10 but also exceptionally high-rate cycling stability, that is, a high capacity of 108.9 mAh g at a very high charge-discharge rate of 50C with a capacity retention of 80 % after 1000 cycles. This improved electrochemical performance resulted from the combination of stable redox reversibility of PI and high electronic conductivity of the graphene additive. The graphene-based composite also exhibited much better performance than composites based on multi-walled carbon nanotubes and the conductive carbon black C45 in terms of specific capacity and long-term cycling stability under the same charge-discharge rates.

“…Thus, many efforts are centered on buffering the large volume variations. The main strategies to overcome this problem are focused on reducing the particle size and/or coating the active material with a conductive material such as carbon or graphene,, or even with a non‐conductive material such as metal oxides ,. A novel strategy lately in vogue is to synthetize antimony‐based intermetallic alloy compounds (MSb x , where M=Ti, In, Cu, Mn, Co and Zn, and x=1, 2, 3) based on an inactive phase that does not react with lithium, and an active phase that it does .…”

In this work lithium ion capacitors (LICs) built using a TiSb2 alloy as the negative electrode and activated carbon (AC) derived from recycled olive pits biomass as the positive electrode are reported. TiSb2 shows high capacity (360 mAh g−1 at 10 C) and excellent rate capability performance together with exceptional volumetric features, enabling its use as a promising candidate for high power requiring technologies. So far, to the best of our knowledge, this is the first Sb alloy‐based LIC ever reported. In order to maximize the output performance, the influence of the mass ratio of the active materials (TiSb2 : AC) is studied. The best TiSb2‐based LIC is able to deliver an energy density as high as 167 Wh kgAM−1 (78 Wh dm−3) at 115 W kgAM−1 (53 W dm−3), more than a 6‐fold increase with respect to its EDLC counterpart. Under high power demanding situations, i. e., 11 kW kgAM−1 (6 kW dm−3), it retains up to 90 Wh kgAM−1 (48 Wh dm−3), which is among the best reported values for LICs. In addition, the device with the most appropriate mass ratio presents an encouraging 80 % retention of the initial capacitance after 10000 charge‐discharge cycles at tdischarge=11 s.
