Company Overview

About ZincFive

ZincFive is an energy storage company founded in 2016 and headquartered in Tualatin, Oregon, that designs and manufactures nickel-zinc (NiZn) battery systems for uninterruptible power supply (UPS) applications in data centers and other mission-critical infrastructure. ZincFive's patented nickel-zinc chemistry offers a superior alternative to both lead-acid batteries (the incumbent technology) and lithium-ion solutions: it delivers higher power density, operates without thermal runaway risk (a key safety concern with lithium-ion in enclosed data center environments), requires minimal maintenance, and is 96% recyclable by design.

Business Model & Competitive Advantage

In December 2025, ZincFive closed an oversubscribed $30M Series F funding round, bringing total funding since founding to $254M. The round was backed by climate and industrial investors including Helios Climate Ventures, Climate Investment (CI), Japan Energy Fund, General Ventures, and Clear Creek Investments. The company has deployed nearly 2 GW of nickel-zinc battery backup cabinets across the global data center industry, establishing it as a commercially scaled alternative UPS provider serving hyperscalers, colocation providers, and enterprise data centers.

Competitive Landscape 2025–2026

In late 2025, ZincFive launched the BC 2 AI — a new battery cabinet specifically engineered for the dynamic power profile of AI data centers, which experience rapid and unpredictable load spikes from GPU compute workloads that legacy UPS batteries are not designed to handle. ZincFive's technology is backed by nearly a decade of proven field performance, and its chemistry maintains conductivity even in weak or depleted cells — providing more reliable backup power than competing alternatives during grid disturbances and power transitions.
