Lithium battery applications

lithium battery application
  • The application of electric vehicles

    At present, most of my country’s electric vehicles still use lead-acid batteries as power. The battery itself has a mass of more than ten kilograms. If a lithium-ion battery is used, the mass of the battery is only about 3 kg. Therefore, it is an inevitable trend for lithium-ion batteries to replace the lead-acid batteries of electric bicycles, so that the lightness, convenience, safety and cheapness of electric vehicles will be welcomed by more and more people.

  • The application of electric vehicles

    For my country, automobile pollution is becoming more and more serious, and the damage to the environment such as exhaust gas and noise must be controlled and treated, especially in some densely populated and traffic-congested large and medium-sized cities. Therefore, a new generation of lithium-ion batteries has been vigorously developed in the electric vehicle industry due to its non-polluting, less pollution, and energy diversification characteristics. Therefore, the application of lithium-ion batteries is another good strategy to solve the current situation.

  • Aerospace applications

    Due to the strong advantages of lithium-ion batteries, aerospace organizations also use lithium-ion batteries in space missions. At present, the important use of lithium-ion batteries in the aviation field is to provide support for calibration and ground operations during launch and flight; at the same time, it is beneficial to improve the efficacy of primary batteries and support night operations.

  • Other applications

    From electronic watches, CD players, mobile phones, MP3, MP4, cameras, video cameras, various remote controls, shaved knives, pistol drills, children’s toys, etc. From emergency power sources in hospitals, hotels, supermarkets, telephone exchanges and other occasions, power tools are widely using lithium-ion batteries.

  • Aerospace special applications

    Special weapons, robots, AGVs, rail transit, medical electronics, emergency backup, exploration and mapping, commercial finance, instrumentation, consumer electronics and other fields have lithium-ion batteries to play a huge role.

The difference between lead-acid and lithium batteries

lithium battery vs acid battery

Comparing lithium batteries and lead-acid batteries, we need to do it from the perspectives of weight energy density, volume energy density, service life, price, applicability, national policy, safety, and environmental protection:

1. Gravity energy density

The current energy density of lithium batteries is generally 200~260wh/g, and lead-acid is generally 50~70wh/g, so the weight energy density of lithium batteries is 3~5 times that of lead-acid, which means that under the same capacity, lead The acid battery is 3 to 5 times that of the lithium battery, so the lithium battery has an absolute advantage in the lightweight of the energy storage device.

2. Volumetric energy density

The volume capacity density of lithium batteries is usually about 1.5 times that of lead-acid batteries, so under the same capacity, the volume of lithium batteries is about 30% smaller than that of batteries.

3. Use cycle

At present, the more popular material systems are ternary and lithium iron. The cycle times of ternary power lithium batteries are usually more than 1000 times, the cycle times of lithium iron phosphate batteries are more than 2000 times, and the cycle times of batteries are usually only about 300 to 350 times. , so the service life of lithium batteries is about 3-6 times that of lead-acid batteries.

4. Price

At present, the price of lithium batteries is about 3 times more expensive than that of lead-acid batteries. However, combined with the analysis of service life and the same cost, the service life of lithium batteries is still longer.

5. Applicability

Because the safety of lithium batteries is slightly worse than that of lead-acid batteries, various safety precautions need to be taken in use, such as preventing damage to lithium batteries caused by external forces or accidents, because this may cause fire or explosion; The temperature suitability is also very good, so in other suitability, the lithium battery is not inferior to the lead-acid battery.

6. Use occasions

Lead-acid batteries: car starting, electric vehicle batteries,
Lithium batteries: mobile phones, computers, power tools, UPS power supplies, etc. are now also used in electric vehicle batteries.

7. Internal materials

The positive and negative electrodes of lead-acid batteries are lead oxide, metal lead, and the electrolyte is concentrated sulfuric acid.
The positive and negative electrodes of the lithium battery are lithium cobalt oxide/lithium iron phosphate/lithium manganate, graphite, and organic electrolyte.

8. Security

The safety of lithium batteries comes from the stability and reliable safety design of positive electrode materials. Lithium iron phosphate completely solves the hidden safety problems of lithium cobaltate and lithium manganate. Lead-acid batteries will explode under strong collision, while iron phosphate Lithium has undergone rigorous safety tests and will not explode even in violent collisions.

9. Environmental protection

LiFePO4 batteries do not contain any heavy metals and rare metals, are non-toxic, have no pollution in production and use, comply with European RoHS regulations, and are environmentally friendly batteries. However, there is a large amount of lead in lead-acid batteries. If they are disposed of improperly, they will still cause secondary pollution to the environment.

10. Operating temperature range

The operating temperature range of the lithium battery is -20-60°C, no air conditioning is required, and equipment installation costs, maintenance costs and electricity costs are reduced. The operating temperature range of lead-acid batteries is 15-35 °C.

11. Discharge characteristics

For the same fully charged lithium battery and storage battery, at the same temperature, using different rates of discharge current, the discharge output characteristics of lithium batteries are very stable, while the discharge output characteristics of batteries are very different, which will cause power instability.

Which is better, battery or lithium battery?

Lithium batteries are better. Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume specific energy or weight specific energy. Lithium batteries are smaller and lighter. Long cycle life. The battery is not efficient. The battery pack is bulky, resulting in a heavy body, short mileage, and the need for regular maintenance of the battery.

Why Lithium Batteries are the Future?

Lithium battery is a kind of battery. The reason why it is more forward-looking than other batteries is mainly because of its high safety, small size and high energy density. The 1980s was also the dawn of mobile device research and development. Lithium batteries The appearance also just conforms to the development of the times.

“Continuously exploring what customers and society need in our daily life, and how we can use science and technology to meet these needs, this is what researchers have to do. Rather than thinking seriously about what new discoveries are, make some adjustments and aimlessly Think about it, and sometimes inspiration will naturally emerge.” Yoshino Akira said.

Previously, the electrolyte (a solution containing ions) in batteries was water, he said. When a voltage of 1.5V or more is applied to water, the water is decomposed into hydrogen and oxygen. Therefore, in the past, it was impossible to obtain an electromotive force exceeding 1.5V. By replacing water with an organic solvent and using carbon in the negative electrode, an electromotive force of more than 4V can be obtained.

In addition, by using lithium cobalt oxide (a metal oxide containing lithium ions) for the positive electrode, Asahi Kasei was the first in the world to propose a prototype of a lithium battery. This small battery can be used in various electronic devices such as mobile phones, notebook computers, digital cameras and video cameras, portable music players, etc., so its appearance is heavyweight.

FAQ of lithium batteries?

  • Why does the constant voltage charging current gradually decrease?
    Because when the constant current process is terminated, the electrochemical polarization inside the battery remains the same level as in the whole constant current. During the constant voltage process, under the action of a constant electric field, the concentration polarization of the internal Li+ is gradually eliminated, and the migration number of ions is reduced. And the speed is manifested as a gradual decrease in the current.

  • What is open circuit voltage?
    The open-circuit voltage is about 4.1-4.2V after full charge, and the open-circuit voltage is about 3.0V after discharge. Through the open-circuit voltage of the battery, the state of charge of the battery can be judged. What is the working voltage? The discharge working voltage is around 3.6V.

  • Why requires to age?
    After the battery is manufactured, the internal positive and negative materials are activated by a certain charging and discharging method, and the process of improving the battery’s charging and discharging performance, self-discharge, storage and other comprehensive performance is called formation, and the battery powder can only reflect its true performance after being formed.

  • What is capacity grading?
    During the manufacturing process of the battery, the actual capacity of the battery cannot be completely consistent due to technological reasons. Through a certain charge and discharge system detection, the process of classifying the battery by capacity is called capacity division.
