This invention discloses a lithium-sodium hybrid ion battery and battery pack. The lithium-sodium hybrid ion battery includes: a positive electrode, a negative electrode, an electrolyte, and a lithium-ion exchanger. The positive electrode contains a sodium-ion positive electrode material; the negative electrode contains a lithium-ion negative electrode material; the electrolyte is a lithium-ion battery electrolyte; the lithium-ion exchanger is disposed on or in at least one of the positive electrode, the negative electrode, and the separator, and is used to replenish lithium ions in the electrolyte during battery charging and discharging. By incorporating a lithium-ion exchanger to replenish lithium ions in the electrolyte during charging and discharging, the lithium intercalation capacity of the negative electrode and the overall capacity of the cell are improved, solving the problem that the actual capacity of commercial lithium-sodium hybrid ion batteries is far lower than the design value due to insufficient lithium-ion supply in the electrolyte.

The invention discloses a method and a device for measuring distribution of an adhesive of a coated pole piece, and belongs to the technical field of coated pole pieces, the method for measuring distribution of the adhesive of the coated pole piece comprises the following steps: sequentially stripping the adhesive of a measurement sample for multiple times, and obtaining the weight of the measurement sample before and after stripping; and determining the distribution uniformity of the adhesive in the coated pole piece according to the weight of the measured sample before and after stripping.

This invention relates to an anode material, its preparation method, and its application. The anode material comprises carbon nanotubes and a silicon layer coating the carbon nanotubes. The anode material of this invention can reduce the resistance of the anode sheet, improve rate performance, and further alleviate the volume expansion problem. Furthermore, by combining single-walled and multi-walled carbon nanotubes, the anode material possesses a richer microporous and mesoporous structure, which can further provide a buffer gap for silicon expansion. Moreover, by configuring the carbon nanotubes to include both single-walled and multi-walled carbon nanotubes, a highly efficient conductive network can be achieved, resulting in high conductivity and further improving the rate performance of the anode sheet.
