Here are some facts you need to know about Nimh battery.

How do NiMH batteries work?

The electrochemical process that occurs between two electrodes is the foundation of NiMH (nickel metal hydride) batteries.

Metal hydride (MH) negative electrode and nickel hydroxide (NiOOH) positive electrode serve as the cathode and anode, respectively.

A reduction reaction starts at the cathode of the battery when it is being charged, and an oxidation reaction starts at the anode. NiOOH receives protons (H+) and electrons (e-) at the cathode to create Ni(OH)2. The metal hydride donates protons and electrons to the metal at the anode, where they combine to generate hydrogen. While the protons move through the inner electrolyte, the liberated electrons migrate from the outer anode to the cathode, generating current. 

Cathode: NiOOH + H2O + e- → Ni(OH)2 + OH-
Anode: MH + OH- → M + H2O + e-

During discharge (when the battery is being used to power a device), these reactions are reversed. The Ni(OH)2 at the cathode is oxidized to form NiOOH and a proton, and the metal at the anode accepts a proton and an electron to form a metal hydride.

Cathode: Ni(OH)2 + OH- → NiOOH + H2O + e-
Anode: M + H2O + e- → MH + OH-

Since NiMH batteries are rechargeable, these chemical reactions can be repeated numerous times, making these batteries a durable, economical and environmentally friendly power source.

What is a nimh battery made of?

NiMH batteries consist of a nickel hydroxide positive electrode, a hydrogen storage alloy negative electrode, a diaphragm paper, an electrolyte, a steel case, a top cover and a sealing ring. In cylindrical cells, the positive and negative electrodes are wound together separately with diaphragm paper and then sealed in a steel case. Nickel-hydrogen batteries use nickel hydroxide as the positive electrode, hydrogen storage alloy as the negative electrode and potassium hydroxide solution as the electrolyte.

In general, NiMH batteries have a cylindrical structure with a nickel-plated steel barrel as the casing and a negative electrode, a cap for the positive electrode and a safety venting device. The active substances of the positive electrode are NiOOH (when discharging) and Ni (OH)2 (when charging), the active substances of the negative plate are H2 (when discharging) and H2O (when charging) and the electrolyte is made of potassium hydroxide solution.

Can NiMH batteries be shipped by air?

Yes. NiMH (nickel metal hydride) batteries can typically be transported by air, however specific requirements and laws must be followed to guarantee safety. There are regulations for the air shipment of batteries from the International Air Transport Association (IATA) and the Department of shipment (DOT).
Nickel-metal hydride batteries are required by law to be packaged safely to prevent movement or damage and to be safeguarded against short circuits. You must either pack each battery separately or cover the terminals of loose batteries with non-conductive covers.

Additionally, particular state-of-charge requirements must be met for batteries being carried by air. For instance, according to IATA standards, batteries delivered by air cannot be charged above 30% of their rated capacity.

NBCELL has a wealth of experience transporting batteries securely and in accordance with all laws. We are able to offer custom logistics solutions that satisfy your unique requirements and give you a smooth and dependable experience.

How to charge NiMH battery?

Advise using a smart charger made especially for NiMH technology to charge NiMH battery. These chargers initially charge the battery at higher rates until it reaches its maximum capacity. The charger automatically changes to trickle charge mode to preserve the battery’s full capacity once it has been fully charged. NiMH battery should not be overcharged. Overcharging a battery can lead to heat buildup and battery damage.
