The global Nickel-Cadmium (Ni-Cd) battery market for uninterruptible power supply (UPS) systems is projected to expand steadily from US$ 2,873 million in 2025 to US$ 4,149 million by 2032, growing at a CAGR of 5.5%. Known for long life, high reliability, and high-temperature tolerance, Ni-Cd batteries remain essential for industrial UPS systems, critical infrastructure, and harsh operating environments worldwide.
What Are Nickel-Cadmium Batteries and How Do They Work?
Nickel-Cadmium batteries utilize nickel oxide hydroxide as the positive electrode and cadmium as the negative electrode. Designed for rechargeable UPS applications, they provide stable performance under extreme temperatures, deep discharge, and continuous industrial operation. Compared with lead-acid and some lithium batteries, Ni-Cd batteries offer superior reliability, long cycle life, and resistance to harsh environmental conditions.
How Is the Ni-Cd UPS Battery Industry Structured?
The Ni-Cd UPS battery industry is divided into three segments:

-
Upstream: Produces nickel oxide, cadmium metal, separators, potassium hydroxide electrolyte, steel casings, and plate-making machinery.
-
Midstream: Manufactures battery plates via pocket, sintered, or fiber technology, assembles cells, fills electrolytes, seals and tests batteries, integrates safety features, and configures UPS battery racks.
-
Downstream: Involves UPS integrators, industrial engineering firms, utilities, oil & gas operators, and transportation companies deploying Ni-Cd batteries with maintenance and recycling services.
This structure ensures high-quality batteries that meet industrial standards and environmental regulations.
