What is a Technology Strategy assessment on zinc batteries?

This technology strategy assessment on zinc batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

Are zinc-ion batteries a promising energy storage technology?

Zinc-ion batteries are touted as promising energy storage technology. The inherent safety and lower cost of zinc-ion batteries — compared to lithium-ion batteries — make them a potential solution. The uses of such batteries are said to be many.

What is a zinc ion battery?

Zinc -ion batteries from Enerpoly are designed to address a wide range of energy storage needs, including grid stabilization, backup power, and applications requiring high levels of reliability. The applications for zinc-ion batteries are especially relevant in maritime settings, critical infrastructure, and densely populated urban areas.

Is enerpoly the world's first zinc-ion battery megafactory?

Enerpoly's zinc-ion battery megafactory. Stockholm-based Enerpoly has opened the world’s first zinc-ion battery megafactory, which will start production in 2025. Founded in 2018, the company is known for making zinc-ion battery cell technology, which could play a significant role in the transition to a clean energy future.

Should we invest in Zn battery science and Technology?

Public investment in Zn battery science and technology has been modest compared with the scale of the investments in Li-ion batteries. Thus, even modest incremental investments—ranging from fundamental science, as noted above, to tools for those interested in moving technologies to products—would be useful.

How much energy does a Zn-Ni battery have?

Zn-Ni batteries have a practical energy density of up to 140 Wh/kg or 300 Wh/L and are capable of approximately 500 charge-discharge cycles [5, 10]. Zn–Ni cells also use an aqueous solution of KOH as the electrolyte and Zn as the anode material, with the same fundamental anode reaction during discharge.
