To mitigate the environmental impact of the improper disposal of spent LiFePO4 batteries and reduce resource waste, the development of LiFePO4 recycling technologies is of paramount importance. Meanwhile, olivine‐structured NaFePO4 in sodium‐ion batteries has received great attention, due to its high theoretical specific capacity of 154 mAh g−1 and excellent stability. However, olivine NaFePO4 only...
Li–oxygen battery provides much higher specific energy density compared to conventional Li–ion batteries, but there is a lack of desired cathodes which show lower over-potential during the charging cycle. Here, we report the effect of surface morphology of carbon-free spinel-like NiCo2O4 nanowires and nanosheets on Ni foam on cathode performance in Li–O2 battery. Two hierarchical structured NiCo2O...
A waterproof membrane made in-house is applied on the lithium air battery, which can effectively block the water molecules and carbon dioxide in the air, so as to reduce the occurrence of the side reaction, e.g. lithium ions react with water or carbon dioxide to form lithium hydroxide or lithium carbonate. Physicochemical analyses are conducted via XRD (X-ray diffraction), SEM (scanning electron microscope),...
