Electrochemical Properties of Li2ZnTi3O8/C Nanomaterials

Li2ZnTi3O8anode: design from material to electrode and devices

“…It is well known that carbon sources have great effects on the uniformity of the carbon layer, conductivity of the LZTO@C, and then the electrochemical performance including reversible specific capacity, cycling performance, and rate capability. Various carbon sources have been exploited, including lithium citrate, 96 asphalt, 97 phenolic resin, 98 sucrose, 99 titanium isopropoxide, 100 glucose, 101 citric acid, 102 oxalic acid, 95 alginic acid, 50 and β-cyclodextrin. 67 The results demonstrated that the electrochemical performance of LZTO@C could be enhanced via the carbon coating (Table 2).…”

“…Apart from the conventional carbon coating, heteroatom-doped carbon to coat on LZTO particles has also been widely studied to further enhance the electrochemical performance of LZTO electrodes, such as N-doped carbon coating, 105 F-doped carbon coating, 99 and N,S-codoped carbon coating 35 (Table 2). It is reported that N-doped carbon can further improve the electronic conductivity of carbon-based materials and produce a large number of defects, thus benefiting the diffusion of Li + ions.…”

“…A. Stenina et al synthesized F-doped carbon-coated LZTO via the sol–gel route using polyvinylidene fluoride as the F source and compared the electrochemical performance of LZTO, LZTO/C, and LZTO/C–F. 99 LZTO/C–F had the largest specific capacity and the lowest degradation during cycling. 227 and 140 mA h g −1 values were maintained at 0.02 and 0.8 A g −1 , respectively.…”
