Abstract

All solid state batteries are essential candidate for miniaturizing the portable electronics devices.

A novel nano-Sn particle/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/poly(vinyl alcohol) core–shell hierarchical composite as high-performance anode material for lithium ion batteries

“…With the development of the electric vehicles (EVs) and the hybrid electronic devices (HEVs), the conventional graphite anode with theoretical capacity of *372 mA h g -1 cannot meet the demands of high energy and power densities for nextgeneration lithium ion batteries (LIBs) [1][2][3][4]. Therefore, novel anode materials with high energy and power densities, good cycling stability and rapid-rate capability are urgently required [5][6][7].…”

All Metal Nitrides Solid‐State Asymmetric Supercapacitors

“…Recently, such GNS substrates have been applied to SnO 2 and ZnO-based electrodes to improve LIB performance. [ 41,42 ] In this work, we report the fabrication of nanostructured metal nitrides on vertically aligned graphene nanosheets substrate for high-power and ultrastable solid-state ASCs. Atomic layer deposition (ALD) was employed in order to assure the maximum use of the conductive GNS surfaces and have full coverage and tight connection of the active nitride material to the substrate.…”

Carbon‐Encapsulated SnO2 Core–Shell Nanowires Directly Grown on Reduced Graphene Oxide Sheets for High‐Performance Li‐Ion Battery Electrodes

“…Figure 2c shows representative X-ray diffraction (XRD) patterns,r evealingt hat the C@SnO 2 core-shell NWs are directly synthesized on the RGO nanosheets.A fters ynthesizing SnO 2 NWs via the CVD process at at emperature of 900 8Cu nder Ar gas flow (Figure 2ciii), the disappearance of the C(002) peak detected at 2q = 11.98 clearlyi ndicates the successful reduction of the GO layers into the RGO layers. [22,23] Thet hree peaks observed at 2q = 26.58,3 3.88,a nd 37.98 indicate the tetragonal rutile phase of the SnO 2 NWs (JCPDSC ard No.4 1-1445). [21,24] Thei ncreased peak intensity of the C@SnO 2 NW structures at 2q = 26.58 might be attributed to the formation of the carbon shell layers (Figure 2civ).…”
