Abstract: Provided is a composite binder for an electrode sheet, and a preparation method for and a use of the composite binder. The composite binder for an electrode sheet uses both a fluorine-containing polymer and an aromatic polyamide. Compared with using a fluorine-containing polymer alone, the strength of the composite binder of the present application is enhanced, the peeling strength of the battery electrode sheet is higher, and the electrolyte infiltration effect is better. Compared with using aromatic polyamide alone, the moisture content of the battery electrode sheet is lower, the hygroscopicity is reduced, and the internal resistance of a battery cell is also lower. That is, the composite binder for an electrode sheet of the present application can have both the advantages of good electrochemical performance of the fluorine-containing polymer and high bonding strength of the aromatic polyamide, and the use cost of the binder is also reduced.

Abstract: The present application provides a soft pack battery, which comprises a packaging film provided with at least one breathable hole. The soft pack battery further comprises a breathable membrane. The breathable membrane seals the breathable hole, and the breathable membrane can block liquid while allowing gas to pass through. The gas in the soft pack battery can be discharged through the breathable membrane, thereby improving the safety performance and the service life of the battery.

Abstract: The disclosure provides preparation methods of a solid-state battery and a battery array, and a solid-state battery. The above preparation method adopts powder sintering 3D printing manufacturing technology, which can increase the interfacial contact among different materials, and improve the contact interface between the electrode and the solid-state electrolyte, thereby obtaining a better ion conduction path. Through printing, annealing and cooling layer by layer, the internal stress, the interlayer effect and the interface effect are eliminated, and defects are reduced, which makes the structure of the prepared positive electrode, negative electrode, solid-state electrolyte and the entire solid-state battery more stable.

Abstract: A negative electrode material includes a dopant containing a first dopant and a second dopant, the first dopant contains a boron element, and the second dopant contains at least one selected from a group consisting of a nitrogen element, an oxygen element, a fluorine element, a phosphorus element, and a sulfur element. Two or more types of dopants are added in the particle producing process, so that the negative electrode material prepared has excellent high and low temperature cycle performance and rate performance. Furthermore, a carbonization coating process is omitted which is compatible with the preparation process of the conventional graphite negative electrode, thus the preparation process is simpler, the equipment required is less, and the cost is lower. A preparation method thereof is provided as well.
