Graphene-supported binary active Mn0.25Co0.75O solid solution derived from a CoMn-layered double hydroxide precursor for highly improved lithium storage

“…S3a †), which can be ascribed to the conversion reaction 25,29 from CoO to Co. It is interesting to note that the initial reduction peak at 0.6 V is found to shi to 0.42 V, which can be assigned to the redox conversion reaction 30 of MnO. Such a shi is also observed for the pure MnO/G aer the second and third cycles (Fig.…”

Porous NaTi2(PO4)3 Nanocubes Anchored on Porous Carbon Nanosheets for High Performance Sodium-Ion Batteries

“…The ZnO/C slices were washed using 6 mol L −1 aqueous HCl solution to form porous carbon nanosheets. These carbon nanosheets were washed by deionized water and absolute ethanol, then dried in vacuum at 50°C for 8 h. Similar process was used to prepare the MnO/graphene composite using oleic acid as carbon sources (Guo et al, 2015). …”

“…Thus, to obtain better electrochemical properties, the contents of conduction materials should be increased. It has been found that the embedding of anode materials in carbon/graphene matrixes can realize high content of conductive carbon materials for enhanced electrochemical properties (Fu et al, 2015; Guo et al, 2015; Choi et al, 2016; Sun et al, 2016). Motivated by the above potentials, we have prepared porous NaTi 2 (PO 4 ) 3 nanocubes anchored on porous carbon nanosheets (NaTi 2 (PO 4 ) 3 /C) through ultrasonic treatment.…”

Facial fabrication of few-layer functionalized graphene with sole functional group through Diels–Alder reaction by ball milling

“…Graphene, a 2D sheet of sp 2 -hybridized, networked carbon, has received considerable attention due to its unique properties, such as its high surface area, and unique mechanical, thermal, and structural properties, since its discovery in 2004. 1 The use of graphene is promising in various applications, such as in supercapacitors, 2 Li-ion batteries, 3,4 sensors, 5 composite additives, 6 transparent conducting electrodes, 7 fuel cells, 8 eldeffect transistors, 9 and photovoltaic cells. 10 Graphene is produced by two types of methods: bottom-up and top-down methods.…”
