Three-dimensional battery structure with cathodes, anodes, and current-reducing devices
The patent application (Publication Number: US20240030569A1) describes a novel battery design comprising a battery enclosure with multiple anodes and cathodes connected in parallel to their respective current collectors. The battery includes an electrical current-reducing device layer to enhance safety and performance.
Specifically, the battery features an electrical current-reducing device layer made of electrically conductive positive-temperature-coefficient (PTC) polymer or an electrically conductive polymer with conductive particles that increase electrical resistance upon thermal expansion. The anodes can be lithium ion insertion electrodes or materials like graphite, titanate, silicon, aluminum, or tin, while the cathodes can be materials such as LiCoO2, Li(NixCoyAlz)O2, LiFePO4, or Li2MnO4. Additionally, the design includes fins protruding from the anode and cathode current collectors, with the electrical current-reducing device layer positioned adjacent to either the anode or cathode current collector. The innovative battery design aims to improve efficiency and safety by utilizing advanced materials and configurations.
