2. 6. Lignin- and PAN-based carbon fibres as negative electrodes for alkali-ion batteries

   Author : Kevin Peuvot; Göran Lindbergh; Dan Zenkert; Enn Lust; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hard carbon; lithium-ion batteries; sodium-ion batteries; potassium-ion batteries; lignin-based carbon fibres; PAN-based carbon fibres; free-standing electrodes; Chemical Engineering; Kemiteknik;

   Abstract : The development of sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) have accelerated since they can now reach similar gravimetric energy densities as lithium-ion batteries (LIBs) but with a lower environmental impact. Hard carbon is the most common negative electrode for SIBs and KIBs and can be made from renewable resources such as lignin. READ MORE
