Lithium Battery Cells-Quantity, Type And Recharging

Jun 29, 2020   Pageview:65

The modification of lithium batteries has gradually advanced in making more products that are stable. Lithium-ion batteries are very successful lately as they are found in mobile phones, laptops, etc.

Their popularity stems from the very fact that their uses are more among other energetic batteries available within the market. However, they were there in the news for bursting into flames from time to time.

How many cells are in a lithium-ion battery?

Lithium-ion batteries are prominent. It is due to their vital advantages when placed as compared with other rival technologies. They're lighter than other rechargeable batteries that are of comparable sizes.

The electrodes of lithium batteries comprises of carbon and light-weight lithium. Consequently, lithium is an increased reactive element. It suggests that much energy is there in its atomic bonds. The regular lithium battery can practically keep about 150-watt-hours of electricity in only one kilogram of battery while a NiMH battery pack can store about 100-watt-hours for one kilogram.

Number of cells in a lithium battery

1.    Battery Voltage Rating / Nominal Voltage Rating = cells in series

2.    Battery Capacity / Nominal Capacity =  cells in parallel

3.    number of cells in series X cells in parallel = total cells

Let us consider an example:

  • Battery Voltage Rating = 2.1 V (say)

  • Nominal Voltage Rating = 2.1 V

  • Battery Capacity = 500 mAh (say)

  • Nominal Capacity = 500 mAh

2.1 / 2.1= 1

500 / 500 = 1

1 X 1 = 1 cell

Which type of lithium battery cell is better?

1.Lithium Cobalt Oxide

It also known as lithium-ion cobalt batteries. They comprise of Lithane and cobalt. Also, it has a very high specific energy. The use of these batteries are in phones, laptops, and cameras. They need a cobalt oxide cathode along with the use of graphite carbon as their anode material. Also, their properties make them the favored option for cell phones and other electric devices.

2. Lithium Manganese Oxide

Lithium manganese oxide batteries also are generally called lithium manganate or lithium-ion manganese batteries. They are also known as li-manganese or manganese spinel.

Lithium manganese oxide batteries are essential due to their heat stability. They are safer than different lithium-ion battery types. For this reason, they can use in medical equipment and devices.

3. Lithium Iron Phosphate

Lithium iron phosphate batteries, also referred to as li-phosphate batteries. They use phosphate as a cathode. They possess low resistance characteristics, which enhance their protection and thermic stability.

Other advantages include stability and an extended lifecycle. The completely charged battery is often stored with a slight change to the entire lifespan of the battery's charge. Li-phosphate batteries are often the first cost-effective option. They have a long battery life.

Additionally, these batteries are usually utilized in electronic motorcycles also as other applications that require an extended lifecycle and significant security. Electric transportations use these batteries usually.

4. Lithium Nickel Manganese Cobalt Oxide

It is known as lithium manganese cobalt oxide or NMC batteries. Lithium Nickel Manganese Cobalt Oxide batteries can be produced from several elements common in lithium-ion battery types. They comprise a cathode made from a mixture of nickel, manganese, and cobalt.

Like other lithium-ion battery categories, NMC batteries have a great specific energy density or a huge specific power. This battery type is most typical in power tools and powertrains for vehicles.

The cathode mixture ratio is typically 60 percent nickel, 20 percent manganese, and 20 percent cobalt. It suggests that the staple cost is less than for other lithium-ion battery types. These batteries may come down in cost further in the future, as some battery producers are getting to switch their battery chemistry to a better percentage of nickel so that they will use less cobalt. This battery type prefer for electric vehicles just because of its very low self-heating rate.

5. Lithium Nickel Cobalt Aluminum Oxide

The batteries also are called NCA batteries. Their demand is increasing in electric powertrains and grid storage.

NCA batteries aren't standard within the consumer industry, but are engaging for the automotive industry. NCA batteries produce a high-energy option with a good and long lifespan. But they're not as reliable with comparison to other lithium-ion battery types. Also, they are quite costly.

6.Lithium Titanate

Lithium titanate, also referred to as li-titanate. The biggest advantage of the li-titanate battery is its exceptionally fast recharge time, because of its excellent nanotechnology,.

Manufacturers of electric vehicles and bikes utilize li-titanate batteries. These batteries have less inherent voltage and energy density than other lithium-ion battery varieties.

So, which lithium-ion battery is best among all?

Lithium-ion batteries are available in many types and have a variety of uses. Some current lithium-ion batteries are better for specific applications than others are. The foremost important thing is to settle on the battery, which best suited for your needs.

How long do you recharge a lithium battery cell?

Generally, Li-ion batteries lose their operating performance very quickly if the perfect practice is not following. The most important is how you charge your devices like phones after you've started using it.

Rivals of Li-ion batteries are;

  • Overcharging

  • Mechanical damage

  • heat

  • Increased state of charge for an extended time

All of the simplest charging practices for lithium batteries revolve round the listed rivals. A number of the perfect methods includes:

  • The device should be stored faraway from direct sunlight or heat.

  • Don' t use devices that have fans for ventilation like laptops on the bed. The air exhaust will get obstructed, and warmth will build up.

  • Restrict the mechanical damage should from going to the battery, although it's highly doubtful due to regular utilization. The batteries store much energy. Puncturing will end in shorting, which causes a buildup and eventually cause a fireplace.

Please don't talk on your phone while charging it. If you want to do so, make use of a slow charging USB cable.
