The highly active surfaces of Ni-rich cathodes usually result in rapid surface degradation, which is manifested by poor cycle and rate capabilities. In this work, we propose a simple method to restore those degraded after storage. More importantly, the mechanism degradation recovery are investigated thoroughly. As storage moist air, lithium carbonate (Li2CO3) dominated impurity layer formed tightly coated on LiNi0.70Co0.15Mn0.15O2 particles. Except for Li2CO3 layer, NiO rock-salt structure...
An attractive approach to fabricate high energy density and safe Li-ion batteries was proposed by utilizing a pentaerythritol tetraacrylate-based gel-polymer electrolyte.
In this study, the degradation of a LiFePO<sub>4</sub>/graphite battery under an over-discharge process and its effect on further cycling stability are investigated.
The main reason for the degradation of slightly overcharged NCM/graphite full cells was found to be unstable crystal structure NCM material at a relatively high delithiation state.

LiNi0.8Co0.15Al0.05O2 and graphite–SiOx composites have been considered as potential cathode anode materials for next-generation batteries due to their high specific capacity. It is significant illustrate the degradation mechanism of NCA/graphite–SiOx power under various conditions wide application. In this study, 10 A h were prepared deterioration at different temperatures (25 °C, 45 65 °C) discharge rates (1C 3C) was systematically investigated. The results show that experienced 15.02%...
The development of safe and high-performance Li-metal anodes is crucial to meet the demanded increase in energy density batteries. However, severe reactivity Li metal with typical electrolytes dendrite formation leads a poor cycle life safety concerns. Therefore, it essential develop that passivate toward suppress formation. Carbonate display metal; however, they are preferred above more volatile ether-based electrolytes. Here, carbonate electrolyte gel polymer approach combined LiNO3 as an...
