LG ENERGY SOLUTION, LTD. patent applications published on November 9th, 2023
Summary of the patent applications from LG ENERGY SOLUTION, LTD. on November 9th, 2023
LG Energy Solution, Ltd. has recently filed several patents related to battery technology. These patents cover various aspects of battery design, including separators, electrode assemblies, battery modules, battery packs, and battery racks.
In terms of separators, one patent application describes a separator for an electrochemical device, such as a secondary battery. The separator includes a porous polymer substrate and a porous coating layer on at least one surface of the substrate. The coating layer consists of a binder polymer and inorganic particles. The separator is designed with a thicker end portion to ensure uniform adhesion when adhered to the electrodes.
Another patent application focuses on electrode assemblies for battery cells. The assembly consists of positive and negative electrode current collectors, positive and negative electrodes with mixture layers, and a separator between the electrodes. The negative electrode mixture layer includes silicon active material particles, and a conductive layer is present on at least one surface of the separator.
Battery modules are also a subject of LG Energy Solution's patents. One patent application describes a module consisting of multiple secondary batteries stacked on top of each other, housed within a module case. The module case includes a trap unit on the inner surface of the side plate, which serves a functional or structural role within the battery module.
A battery pack design is also covered by a patent application. The pack includes multiple battery modules seated on a mount plate within a tray. The tray has a front frame, a rear frame, and side covers. A module partition wall separates adjacent battery modules, and a battery energy management system (BEM) assembly is included.
Notable applications:
- Separator design with a thicker end portion for uniform adhesion.
- Electrode assembly with silicon active material particles and a conductive layer on the separator.
- Battery module with a trap unit on the inner surface of the side plate.
- Battery pack with multiple battery modules and a battery energy management system (BEM) assembly.
- Battery rack designed to accommodate battery packs and prevent fire hazards.
- Pouch-shaped battery case with punch edges for holding electrode assemblies.
