Ultra-fine CuCo2O4 nanoparticles were synthesized using a facile co-precipitation method assisted by NaBH4 and CTAB, they explored as supercapacitor electrode material to achieve large specific capacity high rate capability. The CuCo2O4–250 had surface area of 159.6 m2g?1, which provided numerous active sites enhance their capacity. abundant mesopores with pore volume 0.3599 cm3 g?1 effectively...

The high-rate cyclability of Li-rich Mn-based oxide (LMO) is highly limited by the electrochemical polarization resulting from slow kinetic Li2MnO3 phase. Herein, Prussian blue (PB) coating layer with specific redox potential introduced as a functionalized interface to overcome side effect and escaping O on surface LMO, especially its poor rate capability. In detail, PB can restrict large LMO s...

LiNi0.9Mn0.1−xAlxO2 (NMA) (x = 0.01, 0.03, 0.05) cathodes were synthesized via the co-precipitation method and continued with calcination process in a tube furnace at 750 °C under flowing oxygen gas for 12 h. X-ray diffraction (XRD) revealed well-formed high-purity phase hexagonal structure. LiNi0.9Mn0.07Al0.03O2 (NMA 973) had best electrochemical performance lowest redox peak separation, small...
