How Nickel-Zinc Battery Chemistry Works

ZincFive nickel-zinc batteries deliver high-rate immediate power that’s safe for people
and the planet. Our batteries are a combination of a stable and long-lasting nickel positive electrode and a lightweight zinc negative electrode, capable of high discharge rates. When combined with a highly conductive electrolyte, these rechargeable cells offer high power and energy density with low impedance and no risk of thermal runaway. Immediate power for an always-on world.

Powerful

Compared to conventional lead-acid batteries, ZincFive’s nickel-zinc batteries offer up to three times the power density while being half the size and one third of the weight.

This industry-leading power density and small footprint is achieved through the fast electrochemical and transport kinetics of the nickel and zinc electrodes, combined with the highly conductive non-flammable aqueous electrolyte and a cell design that minimizes internal losses. Nickel-zinc battery power density also compares favorably with lithium batteries, without the additional risks associated with highly volatile chemistries. – Hide

Safe

UL 9540A testing shows that ZincFive’s nickel-zinc batteries do not exhibit thermal runaway, making them non-flammable and non-reactive to air and water.

The aqueous electrolyte lacks the flammability and reactivity of organic solvent-based electrolytes used in lithium batteries, which, when failed, can emit toxic fumes. Compared to lead-acid batteries, ZincFive’s nickel-zinc batteries do not out-gas during normal operation. The result is reduced safety-related infrastructure, lower costs, and peace of mind. – Hide

Reliable

Nickel-zinc batteries offer superior reliability compared to lead-acid and lithium-ion batteries. The cells remain conductive even when weak or depleted, thanks to the combination of highly conductive electrolyte that does not significantly change composition as the cell ages or varies in its states of charge as well as the lack of positive electrode grid corrosion.

The inherent safety of nickel-zinc batteries eliminates the need to compromise reliability for safety-related battery shutdowns, as often seen in other volatile chemistries. – Hide

Long Life

The stable, non-corroding positive nickel current collector in nickel-zinc batteries enables a long operating life, up to three times that of lead-acid batteries. Nickel-zinc batteries can operate over a wider temperature range than lead-acid or lithium counterparts.

The combination of small footprint, long lifespan, reliability, and safety contributes to a low total cost of ownership, making nickel-zinc batteries a high-value cost-effective energy storage solution. – Hide

Sustainable

The cradle to grave carbon footprint of a nickel-zinc battery is significantly less than lead-acid or lithium batteries. Nickel-zinc batteries’ lifetime greenhouse gas emissions are four times lower than lead-acid and six times lower than lithium-ion emissions.

+ View More
Nickel-zinc batteries use common, widely available, conflict-free materials. Nickel and zinc are abundant in the earth’s crust, respectively, four and five times more than lithium and lead. They are also fully recyclable, environmentally friendly with a low carbon footprint, and not hazardous. – Hide
