New age electrode with densely functionalized polymeric binder for high-performance lithium and sodium-ion batteries

Rising demand for electronic devices and electric vehicles has increased the dependence on secondary ion batteries. While lithium-ion batteries are already popular, a promising alternative sodium-ion batteries (SIB) are struggling to get wider acceptance due to slow ion kinetics affecting their performance. A new polymer-based binder called PMAI addresses this issue by forming a functionalized solid electrolyte interphase. The study demonstrated that SIB with PMAI as an anode binder can have exceptional performance and cyclic stability.
