   Sammanfattning : Two dimensional (2D) materials have received growing interest because of their unique properties compared to their bulk counterparts. Graphene is the archetype 2D solid, but other materials beyond graphene, such as MoS2 and BN have become potential candidates for several applications. LÄS MER

5. 4. Water-in-polymer Salt Electrolyte (WIPSE) for Sustainable Lignin Batteries

   Författare :Divyaratan Kumar; Xavier Crispin; Ziyauddin Khan; Yury Gogotsi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water-in-polymer salt electrolyte WiPSE ; Lignin batteries; Zn-ion batteries; Sustainability;

   Sammanfattning : Organic electrolytes are widely used in energy storage technologies, but they are known to have safety, cost, and eco friendliness concerns. Water based electrolytes do not have those issues but are limited by their narrow range potential range of operation to 1.2V. LÄS MER
