Improved performance of Zn-Br2 static batteries with internal magnetic fields

Unmet Need: Zinc dendrite growth and cross-diffusion of bromide ions causes failure in Zn-Br2 static batteries.

Flowless zinc bromide (Zn-Br2) batteries show potential as cost-effective, safe alternatives to lithium-ion batteries. However, uneven metal deposition leading to the growth of zinc dendrites limits the efficiency and durability of static Zn-Br2 battery systems. WSU inventors have developed a method to mitigate dendrite growth, corrosion, and cross-diffusion in Zn-Br2 batteries, leading to long life cycles and increased coulombic and voltage efficiencies.

The Technology: Increased performance of static Zn-Br2 batteries through the incorporation of magnetic fields.

WSU inventors have developed a static Zn-Br2 battery incorporating magnetic fields that slow the deposition of zinc, resulting in a reduction of zinc dendrite growth. The technology utilizes magnetic fields of varying strength to create different Lorentz forces, effectively reducing zinc dendrite growth as well as surface corrosion.

Applications:

  • Safe battery technology in hot climates
  • Cost-effective energy storage systems

Advantages:

  • Offers a cost-effective energy storage system
  • Effectively reduce surface corrosion
  • High energy efficiency and durability
  • Long cycling life
