nimh battery Features Of NiMH Batteries

NiMH battery is short for nickelMetal-Hydrogen batteries.These batteries are similar to nickel batteries.Cd batteries, unlike the use of CD as an active element on a hydrogen-absorbing negative electrode.
The main components of the NiMH battery include nickel-Electrolyte of hydrogen oxide cathode, hydrogen-absorbing alloy anode and potassiumhydroxide.The electrode consists of metal hydroxide containing rare earth alloys, which are solid sources of reduced hydrogen.This is oxidized to protons.The electrolyte developed is alkaline koh.
The voltage of the NiMH battery is 1.
2 volts.
The battery is more dense than twice that of lead acid, about 40% higher than the NiCd battery.Although these batteries are prone to memory effects to a lesser extent.Because mercury or lead is not used, they are better for the environment.
NiMH batteries cost more than lead batteriesAcid and NiCd batteries.It has been shown that there are up to 3000 cycles using NiMH batteries at a discharge depth of 100%.These batteries can withstand excessive charging and discharge conditions.
Their impedance is very low.
Sometimes it can affect the battery due to overcharging.Therefore, it is best to keep the timer when charging.These batteries can work in a wide temperature range.
These batteries are mainly used for cameras, mobile phones, pagers, cameras, medical instruments and many low-cost appliances.With advanced technology, these batteries have found their place in automotive applications that require high voltage
