Electrode material and composite electrodes based on a polymer and carbon

總結: The invention describes a composite electrode for lithium ion or redox flow batteries made of organic material with very high cycle stability. For this purpose, a suspension of carbon with PVMPT (poly(vinylphenothiasin)) is applied to a current collector and dried.

技術優勢: Metal free cathode
Long-term stability
Rate capability
Sustainability
Low toxicity
Availability of raw materials
Easy processing
Lower costs
Fast charging

技術應用: battery manufacturers, manufacturers of electrode materials, or users of the finished battery/hybrid supercapacitors
The use of Poly(vinylphenothiazine)s as the cathode material enables longer battery life, fast charging and lower toxicity, which are significant economic advantages compared to existing metal oxide based materials.

詳細技術說明: Batteries deliver better energy densities than supercapacitors. However, supercapacitors can be charged/ discharged faster and more often. The invention lies in between these categories. Organic electrode materials have the potential for higher charging rates and a longer life compared to the materials used in commercial batteries. They also have higher energy densities compared to supercapacitors. Cathode materials are important building blocks in everyday life and can be found particularly in the field of printable electronics, hybrid capacitors for public transport (e.g. buses) or energy recovery. The invention can be used in many ways depending on the goals which are set. For example, battery manufacturers, manufacturers of electrode materials, or users of the finished battery/hybrid supercapacitors can benefit.
