چکیده

Ultrathin LiMn(2)O(4) nanowires with cubic spinel structure were synthesized by using a solvothermal reaction to produce α-MnO(2) nanowire followed by solid-state lithiation. LiMn(2)O(4) nanowires have diameters less than 10 nm and lengths of several micrometers. Galvanostatic battery testing showed that LiMn(2)O(4) nanowires deliver 100 and 78 mAh/g at very high rate (60C and 150C, respectively) in a larger potential window with very good capacity retention and outstanding structural stability. Such performances are due to both the favorable morphology and the high crystallinity of nanowires.

Cycling behaviour of barium doped LiMn2O4 cathode materials for Li ion secondary batteries

In order to improve the cycling performance of LiMn2O4, the spinel phase LiMn2–xBaxO4 (x = 0.01, 0.02 and 0.05) compounds were fabricated by the glycine-nitrate method. The structures of the products were investigated by X-ray diffraction. Electrochemical studies were carried out using the Li|LiMn2O4 and Li|LiMn2–xBaxO4 cells. The capacity loss of Li|LiMn2O4 cell is about 15% after 30 cycles, w...

High-throughput computational design of cathode coatings for Li-ion batteries

Cathode degradation is a key factor that limits the lifetime of Li-ion batteries. To identify functional coatings that can suppress this degradation, we present a high-throughput density functional theory based framework which consists of reaction models that describe thermodynamic and electrochemical stabilities, and acid-scavenging capabilities of materials. Screening more than 130,000 oxygen...
