摘要： A composite silicon-based negative electrode material, a preparation method therefor, a negative electrode sheet comprising same, and a lithium-ion secondary battery are provided. The composite silicon-based negative electrode material comprises a silicon-based material core layer and a metal material shell layer, wherein the metal material shell layer coats the silicon-based material core layer, and the silicon-based material core layer comprises a permeation area formed by the permeation of the metal material shell layer into the silicon-based material core layer. By means of the composite silicon-based negative electrode material and the preparation method therefor of the present application, the conductivity of the negative electrode material is improved, the expansion rate of the core layer formed by the silicon-based material is limited, and the consumption of lithium ions caused by a reaction between an electrolyte and the surface of the silicon-based material is effectively reduced. Therefore, the first-time coulombic efficiency and cycle performance of the lithium-ion secondary battery formed from the composite silicon-based negative electrode material of the present application are improved.

摘要： In some implementations, a metal air battery includes an anode and a cathode opposite to the anode. The cathode may be formed as a textured carbon-based scaffold and include an opening into the metal air battery. The metal air battery may include a nano-fibrous membrane (NFM) containing a liquid electrolyte and a functionalized carbon structure may be disposed between the cathode and the NFM. The functionalized carbon structure may allow moisture and oxygen from ambient air to permeate through the NFM and diffuse throughout the textured scaffold of the cathode. A moisture barrier layer may be laminated over the cathode and positioned, by a user, in one of two states. When in a first state, the moisture barrier layer may seal the opening. When in a second state, the moisture barrier layer may allow the moisture and the oxygen to enter the textured scaffold.

摘要： The invention provides a lithium-ion battery electrode piece and a lithium-ion battery including the same. The electrode piece includes an electrode active material layer disposed on the surface of the current collector and a protective layer disposed on the surface of the electrode active material layer. The protective layer is composed of metal oxide layers and conductive layers alternately stacked in the horizontal direction. The area ratio of the metal oxide layers to the conductive layers is 4:1-1:4, and the thickness ratio is 0.5:1-1:1. According to the invention, by regulating the shape and ratio of the high temperature stability material and the conductive active material on the electrode piece in the process of coating the protective layer, the amount of the two coating materials is precisely controlled to implement the precise regulation of the high temperature stability and rate performance of the electrode piece.
