Advantages and disadvantages of lithium-ion batteries. What industries are lithium-ion batteries used in? In the process of battery development, the advantages of lithium ion battery are more and more, the range of use is also more and more wide, understanding the advantages and disadvantages of lithium ion battery is essential. At present, from the perspective of market development, the application range of lithium-ion battery is more and more extensive. At present, lithium-ion battery has been gradually expanded to electric bicycles, UPS power storage, electric vehicles and other fields.
Advantages of lithium-ion batteries
High energy density: Compared to other battery technologies such as nickel-cadmium batteries, lithium ion batteries are more energy dense and have the opportunity to add capacity, for example by adding more nickel to the cathode.
Small package size and weight: Lithium-ion batteries are ideal for portable consumer products. Designers can choose to use prismatic packages, which are usually thinner than 19 mm, or lithium polymer packages, which are usually thinner than 5 mm. In addition to the size advantage, weight is reduced due to the chemical properties (e.g., solid/gel electrolytes rather than liquid electrolytes) and the packaging used (e.g., foil).
Memory effect: Unlike NiCd batteries, lithium-ion batteries are not affected by memory effect. Memory effect occurs when a battery is partially used and then fully charged for a period of time, which leads to a rapid discharge. In modern batteries, this is more likely to be due to plate clogging due to voltage drops caused by repeated overcharging, which adds internal resistance and lowers the battery's voltage.
Low discharge rate: Lithium-ion batteries have a lower self-discharge rate than other rechargeable batteries, which means they can be unused for long periods of time.
Charge fast: Lithium-ion batteries charge faster than other batteries, twice as fast as hydrogen fuel powered batteries.
Strong adaptability to high and low temperature: lithium ion battery high and low temperature adaptability, can be used in -20℃--60℃ environment, through the process of treatment, can be used in -45℃ environment.
Disadvantages of lithium-ion batteries
Protection: Lithium-ion batteries are temperature-sensitive and chemically complex, so circuitry is needed to protect the battery from overcharge, overdischarge, and overheating.
Premature aging: Lithium-ion batteries are susceptible to capacity deterioration over time; However, storing the battery in a cool environment can reduce the impact. Once the battery is shipped by the manufacturer, it is important to use it as soon as possible in order to provide the maximum battery life to the end user.
Chemistry: Due to the nature of lithium, severe temperature or mechanical shocks can cause ventilation and possible thermal runaway. This requires more extensive testing than other forms of battery technology to demonstrate the stability of the final battery product and prevent potential for foreseeable misuse.
Production costs: Compared to other types of rechargeable batteries, lithium-ion batteries can be expensive to produce.
What industries are lithium-ion batteries used in?
Due to wide ambient temperature and small volume, lithium ion batteries are widely used in power plant energy storage power supply system, power tools, UPS, communication power supply, electric vehicles, aerospace and other fields, and the market demand is very considerable.
With the increasing maturity of lithium-ion battery technology in recent years, as well as various aircraft manufacturers' pursuit of excellence in aircraft performance, lithium-ion battery technology has gradually begun to be put into commercial operation again, which seems to usher in the spring of development in the aviation field. High-performance large-capacity lithium ion battery will further satisfy the new generation of electric civilian aircraft electric power demand, reduce the weight of the aircraft, to promote the civil aircraft manufacturers gradually be used for aircraft emergency lighting, the cockpit voice recorder and flight data recorder, recorder, independent power supply, backup or emergency power supply and main power supply and auxiliary power unit power airborne systems, etc.
2. Military aspects
Lithium-ion batteries are also used in many military applications, and the current development direction is focused on submarine batteries. Although the lead-acid batteries used in modern conventional submarines have the advantages of simple structure, low cost and good maintenance performance, their performance is not ideal, and various countries are actively studying to replace them with lithium ion batteries.
China's military research on lithium-ion batteries is not bad. The navy has long started to use lithium-ion battery packs in small underwater vehicles such as micro-underwater vehicle and mine operation, and has achieved success, and has also actively acquired a wealth of relevant experience and technology.
3. Communication industry
New energy storage lithium ion batteries have been used in the field of communication for a long time. In the information age, especially with the arrival of 5G era, the communication base station is particularly important. Lithium-ion battery is the reliable energy guarantee of communication base station. In the communication industry, there are several important applications: outdoor base stations, indoor and rooftop acer stations with space constraints, indoor coverage/distributed source stations with DC power supply, central computer rooms and data centers, etc.
Compared with lead-acid batteries, lithium-ion batteries do not contain polluting metals in the production and use process, which has a natural environmental advantage. In terms of performance, it is important to have long life, high energy density, light weight and other advantages. With the continuous reduction of the cost of lithium-ion batteries throughout the supply chain, the price advantage of lithium-ion batteries is becoming more and more prominent. In the field of communication and energy storage, the large-scale replacement of lead-acid batteries or the use of lead-acid batteries in combination with lead-acid batteries is not far away.
4. UPS power supply
With the continuous improvement of lithium ion battery technology, as well as people on EPS emergency power supply lead-acid battery caused by pollution rejection, there are also many customers began to use lithium ion battery as UPS power supply battery, UPS power use lithium ion battery as energy storage equipment is a lot of advantages.
The emergence of lithium ion battery as a new energy source is undoubtedly a timely help to solve the problem of natural resources. The battery used in the UPS power supply is lithium ion battery. It is important because the lithium ion battery is very excellent in terms of power storage and performance. Therefore, in the UPS power supply, lithium ion iron phosphate battery has become the best choice.
Summary: Lithium-ion batteries contribute to the new energy reform and drive the intelligent development of the industrial chain. From mobile phones and digital products to electric vehicles, ships, data centers, communication base stations, energy storage, etc., Lithium-ion batteries have been playing an increasingly important role in our lives. In the future, lithium ion battery will show its performance advantages in more fields and bring better solutions to various industries.
