Most Complete Lithium Ion Battery Working Principle

What is a lithium ion battery?

Lithium ion batteries are one of the best batteries to use today, why? Because they are very convenient, portable, and provide security for our electricity, they have a disadvantage is that many disposable batteries will quickly run out of power, which also leads to the need to throw away, incomplete statistics, the global annual throw away billions of lithium ion batteries, which not only caused pollution to the environment but also a waste of resources, in order to change this situation, rechargeable lithium ion batteries were In order to change this situation, rechargeable lithium ion batteries have been invented.

At present, our computers, cell phones, players, etc. are using lithium ion batteries, lithium ion batteries were first discovered in 1912 and began to be widely used in 1991, the basic chemistry was discovered by the American chemist Gilbert Lewis. Related: What is 48v lithium battery?


What is a lithium ion battery? What are its characteristics?

A lithium ion battery is a rechargeable battery also known as a secondary battery, meaning that it can be charged and discharged repeatedly by moving the lithium ions between the negative (anode) and positive (cathode) electrodes. (Disposable batteries are called primary batteries.)

Nowadays, lithium ion batteries are suitable for storing large-capacity electricity, so they are now widely used in cell phones, computers, and other electronic products, like some industrial fields, robots, cars, etc. They also have a figure.

Oh, really? We usually have so much contact with lithium ion batteries in our lives, can I ask what lithium is by the way?

Lithium is a metal found in the natural environment, do you remember the periodic table of elements like a mantra?


Do all lithium ion batteries perform the same?

No. There are many different types of lithium ion batteries, and they come in a variety of sizes, forms, and positive and negative materials, so there is a big difference in performance as well.

Leodar’s lithium ion batteries use lithium titanate in the negative electrode and have the following characteristics: long life, fast charging, high input/output power performance, low temperature operation, and an effective wide SOC range.

Each lithium ion battery is different to meet different needs, you can tell us your needs and we will provide you with the most suitable lithium ion battery.


How do lithium ion batteries compare with lead-acid batteries?

Generally speaking, lithium ion batteries are lighter and faster to charge than lead-acid batteries.

Lithium ion battery benefits:

Lithium ion batteries themselves are lighter and charge faster than lead-acid batteries, and are environmentally friendly in that they do not contain substances that are highly polluting to the environment.


What about the benefits of lead-acid batteries?

Lead-acid batteries are also very convenient, their cost is lower and cheaper.

Which of them is better?

In fact, they are not particularly good or bad, it depends more on our application, environment, and materials.

When we buy batteries, we must choose carefully and inform our sales to see which one is more suitable for us.

How do lithium ion batteries work?

Lithium ion batteries are very popular because they have a number of important advantages over competing technologies.

First of all they are much lighter in mass than other batteries of the same size, which makes it much easier for us to use them in whatever application they are used in. Lithium ion batteries have electrodes made of lightweight lithium and carbon. Lithium is also a highly reactive element, and lithium ion batteries can store a lot of energy in their atomic bonds with very high energy density, which is a way to understand energy density.

A typical lithium ion battery can store 120 watt-hours of power in 1 kg of cells. a NiMH (nickel-metal hydride) battery pack can store about 90 watt-hours per kilogram, although 60 to 70 watt-hours may be more typical. Lead-acid batteries can only store 25 watt-hours per kilogram. With lead-acid technology, it takes 6 kg to store the same amount of energy that a 1 kg lithium ion battery can handle.

Lithium ion battery losses are relatively small, and lithium ion battery packs will only lose about 5% of their power each month, but like some other NiMH batteries, etc., they can lose about 20% each month.

They have a benefit is that we do not have to completely use up the battery before charging, lithium ion battery chemicals do not have to be like other battery substances.

Lithium ion batteries can handle hundreds of charge/discharge cycles. (2022 Most Complete advantages of lithium Ion Battery)


Lithium ion batteries do not only have benefits, but likewise, they have many disadvantages:

  • 1. Lithium ion batteries degrade after they leave the factory, whether you use them or not, they only last two to three years from the date of manufacture.
  • 2. Lithium ion batteries are not resistant to high temperatures, and heat can cause lithium ion battery packs to degrade more quickly than normal, which tends to reduce battery life.
  • 3. Lithium ion batteries will cause a reduction in life if they are completely discharged.
  • 4. Lithium ion battery packs are more expensive because they must have onboard computers to manage lithium ion batteries.
  • 5. Lithium ion can sometimes have safety accidents, and if they fail, they can catch fire and affect safety.


Energy density vs power density

Energy density:

The two most common concepts related to lithium ion batteries are energy density and power density. Energy density is measured in watt-hours per kilogram (Wh/kg) and is the amount of energy a battery can store relative to its mass.

Power density:

Power density, measured in watts per kilogram (W/kg), is the amount of electricity a battery can produce relative to its mass. To paint a clearer picture, think of draining a pool of water. The energy density is similar to the size of the pool, and the power density is comparable to emptying the pool as quickly as possible.
