What is a battery?

Batteries provide power for gadgets like flashlights, mobile phones, and electric autos. When electricity is being supplied, the cathode is the positive terminal of a battery, and the anode is the negative terminal. The negative terminal, which is the source of electrons for an external electric circuit, is marked. An external electric load (such as a battery) will consume high-energy reactants and transform them into lower-energy products through a redox reaction. The resulting free-energy difference is transferred to the external circuit in what is referred to as electrical energy. Traditionally, the term “battery” was used to describe a device with many cells, but its usage has broadened to include single-cell devices.

Which battery is better NiMH or lithium?

The NiMH is a viable alternative to NiCd in many situations. An alloy that can absorb and desorb hydrogen is used in place of cadmium in rechargeable NiMH battery anodes. It is composed of nickel hydroxide as the cathode and an electrolyte consisting of potassium, sodium, and lithium hydroxides in solution. Each cell produces 1.2 volts.

In lithium ion batteries, the anode is made of graphite, and the cathode is made of a lithium-containing combination with another metal. Lithium cobalt oxide (LCO), lithium nickel oxide, lithium aluminum oxide, lithium manganese oxide, and lithium iron phosphate are all possible materials for lithium batteries (LiFePO4). The electrolyte is a combination of organic carbonates in various concentrations.

NiMH Pros


If you have ten different gadgets that all require NiMH batteries, you can use a single battery pack to power them all—though not at the same time, of course. Due to the fact that NiMH employs standard sizes, it is compatible with any devices that use sizes like as AAA or AA.

The battery is completely rechargeable.

I’m referring to the fact that these batteries have the potential to be depleted to zero charge if you can get them to do so. They will still charge; just make sure they don’t suffer from reverse polarity, or else they will be permanently ruined.

NiMH Drawbacks

A high rate of self-discharge.

Every month, NiMH batteries lose a significant amount of their charge. The number is approximately 5 percent in the first week following the charge and approximately 50 percent in the first month following the charge. Low self-discharge (LSD) rate kinds are offered in various configurations. They are more dependable than normal NiMH batteries, although their capacity are smaller, often ranging from 2000mAh to 3000mAh.


NiMH batteries can explode if they are overcharged or short circuited.

Low-Load Devices are often unreliable.

When it comes to gadgets like clocks, NiMH batteries should not be used. They will lose charge more quickly because of self-discharge rather than because of the load. Instead, use alkaline, or lithium ion batteries.
