2. 1. All-organic aqueous Na-ion energy storage devices

   Author : Martin Karlsmo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid supercapacitor; battery; battery supercapacitor hybrid; aqueous electrolyte; All-organic; Na-ion capacitor; energy storage;

   Abstract : Development of all-organic aqueous energy storage devices (ESDs) is a promising pathway towards meeting the needs of technically medium/low-demanding electrical applications. These ESDs should favour low cost, low environmental impact, and safety, and thus complement high voltage and energy/power dense storage such as lithium-ion batteries. READ MORE

4. 2. Wood-derived lignin-based fibers as supercapacitor electrodes

   Author : Azega Rajendra Babu Kalai Arasi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; lignin; green electrode materials; energy storage; supercapacitor;

   Abstract : Today, in order to replace fossil energy sources with renewable energy sources such as solar and wind, reliable energy storage systems that can provide power regardless of the intermittent nature of the energy sources must be created. Especially with the future’s rising energy demands the development of such energy storage systems from green-collar materials with the least negative environmental impact is pressing. READ MORE
