The Challenge of Rechargeable Batteries

　　Rechargeable batteries are the key storage components in many large battery systems. For example, electric vehicles and smart renewable energy grids. With the increasing demand for these battery systems, researchers are turning to more sustainable and environmentally friendly production methods, which use organic materials as electrodes in rechargeable batteries;

　　Organic electrodes shed relatively low environmental traces in the process of production and processing. They are inorganic metal oxide electrodes commonly used in rechargeable batteries, providing a more environmentally friendly alternative. The structure of organic electrodes can also be designed to support the ability of high energy storage. However, the challenge is that the conductivity and stability of organic compounds used in batteries are poor. At present, organic materials used as electrodes in rechargeable batteries are, For example, conductive polymers and organic sulfur compounds face rapid energy loss after multiple charges;

　　Lithium battery for electric vehicle

　　3Q novel advanced materials

　　In order to overcome these limitations, Professor Loh and his research team have synthesized a new organic compound 3Q. Each molecule has at most six charge storage sites to improve its conductivity and energy retention;

　　When hybridizing with graphene and applying it to ether based electrolytes, the team observed that the 3Q based motor showed a conductivity of up to 395 milliampere hours per gram. After multiple charging and discharging cycles, it also showed a strong energy retention capability;
