"Dream Bond," a binder for silicon anodes in lithium-ion batteries. It excels in adhesion to copper foil and alloys, retaining 97% of its capacity after 400 cycles.
Dream Bond is a high-performance binder developed based on polyimide resin, designed for lithium-ion batteries with high temperature durability. It is particularly effective for high-capacity Si-based alloys, maintaining 97% of battery capacity from the 2nd to the 400th cycle in lithium-ion rechargeable batteries using this binder. With this entirely new binder, if high-capacity electrode technology is commercialized in batteries, it can be used in various applications requiring high current with high-capacity batteries. It is a dream material that enables products that exceed the current battery characteristics, such as hybrid vehicles, electric vehicles, and various mobile communication devices with high-definition displays.
