This technology relates to an electrode active material containing tellurium nanotubes with a conductive polymer layer and a method of manufacturing electrodes for secondary batteries.
The technology of using sodium, aluminum, zinc, etc. in the negative electrode is attracting attention as it increases the stability of secondary batteries and is highly price competitive, but there is a problem in that intermediate materials dissolve in the electrolyte during the charging and discharging process, creating a shuttle effect that travels between both electrodes. In order to solve this problem, this technology proposes a technology to synthesize tellurium material in the form of nanotubes and coat it with a conductive polymer.
By using tellurium nanotubes formed with a conductive polymer layer through this technology as an electrode active material, it is more economical than the existing technology of manufacturing electrode active materials by supporting them in a host material to suppress the elution of intermediate materials, and can further contribute to commercialization. The advantage is that the specific gravity of the active material in the electrode does not decrease, increasing energy density. There is.
