Herein, we present the first report on a new strategy to synthesize a kind of stereoregular poly (o-phenylenediamine) (PoPD)-graphene nanocomposite bound only by chemical bond via in situ growth of single-stranded like PoPD onto graphene for high performance supercapacitor. Firstly, aniline groups are grafted onto graphene oxide (GO) surface by diazotization reaction to prepare aniline functionalized...
In order to significantly enhance the elevated-temperature performance of LiSi0.05Mg0.05Mn1.90O4, the LiAlxSi0.05Mg0.05Mn1.90-xO4 (0≤x≤0.08) samples were firstly prepared via sol-gel technique. All the obtained samples showed the intrinsic spinel structure without any other detectable impurity phases. Among these samples, the LiAl0.05Si0.05Mg0.05Mn1.85O4 sample was found to be optimal possessing regular...
