Remarkably the obtained composite shows 1105.2 m Ah/g at a current density of 5000 m A/g after 400 cycles which makes it a promising candidate to improve the volumetric energy density.展开更多

Microscopic investigation of the nanocomposite was carded out by atomic force microscopy （AFM）. The results showed that the shape of the composite was layered and porous. Eu2O3 was grafted when methyl acrylate （MA） polymerized; thus Eu2O3 particles appeared on both sides of the chains of polymeric methyl acrylate （PMA）.展开更多
