Nickel-Cadmium Batteries
Nickel-Cadmium (Ni-Cd) batteries have been a staple in the battery world for decades, known for their robust performance and reliability in a wide range of temperatures and conditions. This guide covers everything you need to know about Ni-Cd batteries, from how they work to tips for safe disposal and recycling.
Nickel-Cadmium batteries are a type of rechargeable battery that uses nickel oxide hydroxide and metallic cadmium as electrodes. Introduced in the early 20th century, these batteries have been widely used in various applications, offering distinct advantages in terms of durability and performance.
Ni-Cd batteries operate through a simple yet effective electrochemical process. During discharge, the nickel oxide hydroxide anode is reduced, and the cadmium cathode is oxidized, producing a flow of electrons that generate electric power.
When charged, the reverse reaction occurs, allowing Ni-Cd batteries to be used repeatedly. Their ability to endure high rates of charge and discharge without damage makes them particularly valuable for certain applications.
Nickel-Cadmium batteries contain toxic heavy metals, which can be harmful to the environment if not disposed of properly. Recycling and proper disposal are crucial to minimize environmental impact.
Recent advancements in battery technology focus on developing alternatives like Nickel-Metal Hydride (NiMH) and Lithium-ion batteries, which offer similar benefits without the environmental drawbacks of cadmium.

Nickel-cadmium (Ni-Cd) batteries are a type of rechargeable battery known for their robust performance in a wide range of temperatures and conditions. They have been used in various applications from portable electronics to emergency lighting and aviation. This FAQ provides detailed answers to common questions about Ni-Cd batteries.
A nickel-cadmium battery is a type of rechargeable battery that uses nickel oxide hydroxide and metallic cadmium as electrodes. Ni-Cd batteries are known for their long life and ability to deliver consistent power output, making them suitable for a wide range of applications.
In Ni-Cd batteries, the positive electrode is made of nickel oxide hydroxide, and the negative contains cadmium. During discharge, the nickel oxide is reduced and the cadmium is oxidized, producing energy. When charging, the process reverses: the cadmium and the nickel oxide are regenerated by an external electrical energy source.
Ni-Cd batteries are used in a variety of applications including:
To maintain Ni-Cd batteries effectively:
Due to the toxic nature of cadmium, Ni-Cd batteries must be disposed of properly. They should be taken to a recycling facility where they can be processed safely. Many countries have regulations that require recycling of Ni-Cd batteries.
Nickel-cadmium batteries have been valued for their durability and performance in various applications, from emergency systems to portable tools. Below, our customers share their positive experiences with Ni-Cd batteries, highlighting their dependable nature and longevity.
