NEGATIVE ELECTRODE MATERIAL COMPRISING NANO-SILICON LOADED ON POROUS CARBON, AND PREPARATION METHOD THEREFOR

Resumen de: WO2026060860A1

The present invention relates to the technical field of lithium ion battery materials, and provides a negative electrode material comprising nano-silicon loaded on porous carbon, and a preparation method therefor. The preparation method comprises the following steps: surface modification of nano-silicon; surface modification of carbon nanotubes and few-layer graphite; preparation of precursor-encapsulated composite microspheres; and preparation of the negative electrode material. In the present invention, when a precursor is dissolved, a surface-modified nano-silicon dispersion and a composite dispersion are added, and high-temperature spray drying is performed to prepare precursor-encapsulated composite microspheres; since the precursor undergoes weight loss due to decomposition of a large number of groups at a high temperature to form a porous loose structure, the volume expansion of silicon can be well buffered; then the precursor-encapsulated microspheres are uniformly dispersed in a prepolymer composition, and after standing polymerization to obtain a gel, vacuum drying, and sintering, a dense high-strength carbon shell is formed on the surface of the loose carbon layer, thereby preventing expansion and damage of the negative electrode material, and improving the cycle stability and rate performance of the negative electrode material.

The battery cells (230) are provided with cell terminals (231), and the cell terminals (231) are in contact with the inner surface of the housing chamber wall (203). The battery cells (230) are in contact with the cooler (250) via the housing chamber wall (203), and therefore the battery cells (230) are cooled by the cooler (250). The battery cells (230) are housed in the housing chamber, while the cooler (250) is outside the housing chamber. Therefore, even if the refrigerant flowing through the cooler (250) were to leak, the leaked refrigerant can be prevented from contacting the battery cells (230).

Resumen de: WO2026063152A1

The present invention is provided with: a plurality of battery modules (210) in which a plurality of plate-shaped battery cells are stacked in the thickness direction of the battery cells, the battery modules (210) being provided in a direction intersecting the thickness direction of the battery cells; and an aggregate terminal (410) that is an end point of an electrical path in which the plurality of battery modules (210) are electrically connected in series. The aggregate terminal (410) extends in a direction along the thickness direction of the battery cells, and the tip of the aggregate terminal (410) protrudes further than the battery modules (210) in the thickness direction of the battery cells. By setting the position of the tip and the orientation of the aggregate terminal (410) in this way, an electrical device connected to the aggregate terminal (410) can be easily disposed relative to the battery pack (400) in the thickness direction of the battery cells.

Resumen de: WO2026061037A1

Provided in the present application are a battery cell, a battery and an electric device. The battery cell comprises a casing, an end cover, an electrode assembly, and a pressure-relief mechanism. The casing has an accommodating space having an opening at one end, and the end cover is connected to the casing and seals off the opening, the end cover being provided with a pressure-relief hole. The electrode assembly is accommodated in the accommodating space. The pressure-relief mechanism is arranged on the end cover and seals off the pressure-relief hole, the pressure-relief mechanism being configured to release the internal pressure of the battery cell. The material of the pressure-relief mechanism comprises steel or nickel, and the material of the end cover comprises steel; the pressure-relief mechanism is welded to the end cover. The material of the pressure-relief mechanism comprising steel or nickel and the material of the end cover comprising steel can improve the structural strength of the end cover and the pressure-relief mechanism, reduce the risk of deformation of the end cover and the pressure-relief mechanism when subjected to a force, and facilitate a reduction in the risk of premature valve opening for pressure relief in the pressure-relief mechanism, helping prolong the service life and enhance the reliability of the battery cell. In addition, the pressure-relief mechanism made of steel or nickel is relatively easy to weld with the end cover made of steel.

BATTERY PACK AND ENERGY STORAGE CABINET

Resumen de: WO2026060996A1

Provided in the present application is a battery pack. The battery pack comprises a box body and, accommodated in the box body, a battery module and a battery management unit (BMU), a bottom surface of the battery module being provided with a circuit board, and a sampling circuit being provided in the BMU. A liquid leakage detection circuit is provided in the circuit board, an isolation circuit being provided between the sampling circuit and the liquid leakage detection circuit. The sampling circuit and the liquid leakage detection circuit are electrically connected to each other by means of the isolation circuit. The sampling circuit comprises a first resistor, the first resistor being connected in series to the isolation circuit. Because an electrolyte is electrically conductive, when the electrolyte of a battery cell leaks onto the circuit board, the resistance value of the liquid leakage detection circuit in the circuit board changes, and therefore the voltage of the isolation circuit changes, such that on the basis of the voltage change at two ends of the isolation circuit, the BMU determines whether the electrolyte in the battery module has leaked.

RIVETING STRUCTURE FOR CELL POSTS

Resumen de: US20260088469A1

Disclosed is a riveting structure for cell posts. A cell comprises a lower shell, an external terminal and a current collector, the external terminal is arranged on an outer side of the lower shell, and the current collector is arranged on an inner side of the lower shell; and the external terminal has an inner surface facing the lower shell and an outer surface backing on to the lower shell. In the invention, the post is fixed to the inner surface of the external terminal and then penetrates through the first through-hole in the lower shell to be riveted to the current collector. In this way, a weld protrusion generated by welding the post to the outer surface of the external terminal is avoided, and the outer surface of the external terminal is smoother and can be in tighter fit with the busbar, thus improving the current stability.
