The phase structure and the morphology were characterized by the X-ray diffraction (XRD) and the scanning electron microscopy (SEM), respectively.
Moreover, the C-rate performance for the composite was also better than that of the pure Li4Ti5O12 resulting from the formation of carbon-based fiber structure.
Recently, Li4Ti5O12 with the spinel structure has been widely researched as the lithium-ion battery anode material because of its high stability [1].
The closed charge-discharge curves for three times are consistent very well, indicating a stable structure for LTO.

Abstract.
Comb-shaped hyper-branched polymers in aqueous solution would form association super-molecular structure, which could be destroyed by Na2SO4 solution.
Its structure consists of a grafted long-chain macromolecule structure; the main chain has large numbers of carboxylic acid groups, with nonionic polyglycol chains as its branch chains.
Slump-retaining polycarboxylate admixture BT could be obtained using the same methods, but water-reducing agents JS-1, JS-2 and JS-3 as well as slump-loss resisting agents BT-1 and BT-2 were prepared by controlling the acid-ester ratio (the molar ratio of acid to ester) and the length of side chain in the structure.
Long side chain falls into nonionic surfactant, without ionic group in structure and then there is no electrical conductivity.
