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

    Författare :Martin Karlsmo; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
