  • High Power

  • Faster Charge

  • Lower Cost

Zinc element on Periodic table

Whether you’re a homeowner looking for a reliable energy storage solution for your solar panels or an engineer exploring new battery technologies, we have everything you need to know about Zinc batteries.

The Problem:

Traditional lithium batteries have been widely used for stationary energy storage due to their high energy density and fast charging capabilities. However, these batteries also present several problems:


Lithium batteries are prone to overheating, short-circuiting, and even exploding. The use of flammable and toxic materials in the battery construction also adds to the safety concerns.

Environmental impact

The manufacturing process of lithium batteries involves the extraction and processing of rare metals, which is resource-intensive. The disposal of used lithium batteries also poses a risk to the environment.


The limited availability of rare metals used in the manufacturing of lithium batteries raises concerns about their long-term sustainability.


The cost of rare metals, coupled with the complex manufacturing process, makes lithium batteries an expensive energy storage solution.
