This technology relates to polymers for binders and lithium secondary batteries containing them. In particular, it is a technology designed to increase performance, durability, stability, and applicability based on core materials, structures, processes, or device configurations related to binder polymers and lithium secondary batteries containing them.
We seek to solve the chronic problems that hinder practical application for high-capacity cathodes, which are reactive and change in the volume of particles. Accordingly, this technology applies as a key means the inclusion of a polymer for a binder with a specific chemical formula and properties, and proposes a technological concept that implements the polymer for the binder's ability to improve the lifespan and energy density of lithium secondary batteries.
Accordingly, the present invention can be expected to improve the lifespan and energy density of lithium secondary batteries, and can also increase reproducibility, scalability, and process suitability in actual use environments. In addition, it can be used as a high-performance material, device, battery, sensor, device, or manufacturing process in related industries, making it advantageous in terms of subsequent commercialization and demonstration.
