Rechargeable, Zinc-MnO2 Cells

HIGH PERFORMING – AFFORDABLE – SUSTAINABLE

Coulomb Technology Inc. develops rechargeable Zinc-MnO2 cells in the USA. We focus on the E-mobility and Energy-Storage (ESS) markets. Our goal is to provide you with comprehensive information about Zinc batteries, including their features, benefits, and applications.

Why Zinc batteries?

Zinc batteries are a new generation of rechargeable batteries that are rapidly gaining popularity as an alternative to traditional lithium-ion batteries. They offer a range of benefits making them an ideal choice for a wide range of applications.

Safety (Virtually no fire issues, no toxic materials, or toxic gas generation)
-20C to 60C Operating Temperature
High RTE & Low Self-Discharge Rate
Uses earth-abundant materials
Much Lower Cost

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:

Safety

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.

Sustainability

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

Cost

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