Argonne Nationwide Lab: Lithium-sulfur batteries are one step nearer to realization
Scientists on the DOE’s Argonne Nationwide Laboratory are researching options to the drawbacks of lithium-ion batteries by testing alternate supplies akin to sulfur.
Sulfur, says Argonne, is extremely cost-effective, and lithium-sulfur batteries can maintain extra power than ion-based ones. In a current research, researchers created a layer within the battery that will increase power storage capability whereas practically eliminating the difficulty often known as shuttling: polysulfides dissolving within the electrolyte and inflicting corrosion that reduces each the variety of recharging cycles and battery life.
Earlier makes an attempt to resolve this drawback with a “redox-inactive” interlayer between the cathode and anode added weight and proved insufficient. However after including a porous, sulfur-containing “redox-active” interlayer, assessments confirmed an preliminary cell capability about 3 times larger than with an inactive layer, and the flexibility to take care of excessive capability over 700 charge-discharge cycles.
