As there are so many types of batteries out there, each of them has different specifications due to their chemistry, form factor, capacity, and charging characteristics. Basic features and specifications of the said batteries are listed below.
The basic and most important thing about nickel-cadmium batteries is voltage. NiCd batteries have a nominal voltage of 1.2 volts per cell. This makes them useful in battery packs for portable electronics and power tools, given that they can be configured into different pack voltages. The capacity and energy of NiCd batteries depend on what application they are in, but generally, one can find capacities between 2000 and 4000 mAh. NiCD batteries are robust and can handle a lot of cycles. Ideally, the life cycle ranges are about 1000-2000 cycles. One interesting thing about NiCd batteries is that they have battery memory. It is recommended not to discharge the battery completely, and recharging it often will help prevent battery memory and help long battery life. NiCd batteries also perform relatively well in extreme temperatures. Charging time for NiCd batteries can be fast. It would only take 1 or 2 hours to complete the charging process.
The features and specifications of Nickel Metal Hydride batteries are similar to that of NiCd batteries, but there is a difference in the chemistry of the battery. The nominal voltage is still 1.2 volts for every cell, and as mentioned earlier, can be configured to any voltage level. But the capacity is much better. One can find NiMH batteries with capacities from 600 to 3000 mAh. The cycle life is less than the NiCd; it is around 300–500 cycles. NiMH batteries have low self-discharge, which means they discharge low when not in use. They also need to be fully charged before full usage. There are more eco-friendly than NiCd as there is no cadmium, which is toxic. There are also enhanced versions of NiMH batteries with features for cordless phones and digital cameras.
The lithium-ion battery nominal voltage is 3.6-3.7 volts per cell. Their capacity also varies a lot, from 1500 to 3500 mAh in most consumer products and light electric vehicles. One of the best features is their cycle life, which is long. A lithium-ion battery can last up to 500-2000 cycles, depending on the charging and discharging rates. Lithium-ion batteries also have a low self-discharge rate, which means they don't discharge themselves when not in use. This battery does not have the memory effect, which is a big plus. They also have fast charging, with certain batteries being able to charge fully in 30 minutes to an hour.
Last is the lithium polymer battery. This kind of battery uses a polymer electrolyte instead of liquid electrolyte. The nominal voltage varies like Li-ion batteries, which are around 3.7-3.8 volts per cell. They offer exceptional capacity. The best thing about LiPo batteries is that they can be molded into many shapes. The cycle life is similar to the Li-ion battery. These kinds of batteries are mostly used in smartphone devices, drones, and electric vehicles. LiPo batteries have safe chemistry. No matter what they undergo, they are less likely to explode, making them safer during transport or storage. All these specifications influence the choice of battery depending upon the required application. It has to do with energy density, form factor, voltage, and environmental concerns.
Choosing the right rechargeable battery for a certain application involves considering several important factors like battery chemistry, capacity, self-discharge, cycle life, safety, form factor, operating conditions, and environmental concerns.
First off, the battery chemistry needs to be considered. NiCd batteries are the GOAT for rugged applications. Applications where the battery has to be cycled many times without failing, and where the end-users might be expected to operate in extreme temperatures, are the best suited for NiCd. The energy density is not that great, but the robustness and long cycle life compensate for this loss. NiCd batteries are also cheap. They are also affordable and are definitely a cost-effective solution for the above-mentioned situations.
On the other hand, NiMH batteries have greater capacity and are environmentally friendlier. They are the best option for applications where high energy density is required but where the likely operating conditions are normal. For example, consumer electronics gadgets and cordless power tools use NiMH batteries, and they can need a long run time and can afford a moderate cycle life. Plus, NiMH batteries have lower self-discharge rates, so they are ideal for devices that tend to be inactive for long periods, like cameras.
Lastly, lithium-ion and lithium polymer batteries are the best for lightweight, high energy density, and potentially fast charge applications. These batteries are the most versatile batteries and are commonly used in portable electronics, medical gadgets, and electric vehicles. They have the highest energy density among all other rechargeable batteries. They are lightweight and don't have a memory effect, so they can be easily recharged without affecting their long-term capacity. These are the best batteries for modern applications.
Other factors to consider when choosing a battery are the space and weight constraints of the application, the required voltage, and the safety standards that have to be complied with. Lithium polymer, for example, offers more flexibility in shape and design as they have puttethermoplastic in a polymer electrolyte. While lithium-ion batteries have been used for general applications. In short, the choice of battery must be driven by its application-specific needs and requirements, balancing performance, safety, cost, and environmental impact.
Nickel-Cadmium NCd batteries are good for industrial applications. They are perfect in places where there need to be frequent recharges, and the devices have to work for a long time. These batteries can recharge themselves over and over again while still completing their job. They work well in extreme environments. They are durable and can take hard conditions. It's no wonder they're used in power tools, cameras, and medical equipment.
