Technology is constantly developing, and there are 5 battery technologies that may replace lithium battery packs in the future. As the heart of new energy vehicles, lithium battery packs have always been the lifeblood of the new energy vehicle industry. Competition in the battery industry is fierce, and mastering core technology is still the key. With the widespread use of new energy vehicles, higher requirements have been put forward for lithium battery performance and usage requirements.

　　Although lithium battery packs are still considered to be the mainstream battery technology in the next decade, new battery technologies are also gradually developing. Today, the editor of Cuneng Electric will make a prediction: We are optimistic about the five battery technologies that may replace lithium battery packs in the future!

　　1. Contains lithium battery

　　In fact, lithium-containing batteries are lithium-air batteries and lithium-sulfur batteries, but their technology is not yet ready, the actual application performance has yet to be tested, and whether its performance is better than that of lithium-ion batteries has not yet been confirmed.

　　2. Next generation lithium-ion battery

　　In order to increase the energy density of lithium battery packs and reduce the number of raw materials required, researchers are currently improving the performance of existing lithium-ion batteries by enhancing or replacing the anode and cathode materials of the battery. According to the International Energy Agency's 2018 Electric Vehicle Outlook report, the new generation of lithium-ion batteries will achieve mass production around 2025.

　　3. No lithium battery

　　Various research groups are trying to think outside the box of lithium battery packs, trying various methods such as graphene supercapacitors and sodium batteries. However, there are doubts whether such batteries can compete with lithium-ion batteries, which are lower cost and already have a good start.

　　4. Solid-state battery

　　Solid-state lithium-ion batteries mean that all components in the battery structure exist in solid form, replacing the liquid electrolyte and separator of traditional lithium-ion batteries with solid electrolytes.

　　Researchers have improved the degree of autonomous driving and extended the range of electric vehicles by replacing the liquid electrolyte in current lithium-ion batteries with a solid electrolyte. Solid-state lithium-ion batteries will have higher energy density and charge faster, while also being safer, more reliable, and longer-lasting.

　　5. Hydrogen fuel cell

　　Hydrogen fuel cells use the chemical element hydrogen to create batteries that store energy. This kind of battery is pollution-free, noiseless and highly efficient, and is widely used in the aerospace field and automotive energy.

　　The most representative lithium-free energy storage technology is the hydrogen fuel cell led by Hyundai, Toyota and Honda. However, expensive hydrogen fuel cell materials have hindered the development of this technology.

　　Factors promoting the development of lithium battery pack technology:

　　1. The global competition for power batteries is becoming increasingly fierce. The most important thing is to gather talents and maintain sufficient R&D investment. Lithium battery pack companies must also cooperate with universities and research institutions with state support to carry out basic research on power batteries.

　　2. We need to jointly cope with challenges and collaborate with upstream and downstream enterprises. Allow power battery manufacturers to participate in R&D and design from the front end with vehicle manufacturers, allowing battery manufacturers to fully understand the supporting needs of OEMs, thereby avoiding the cost increase caused by fighting on their own and opaque information, and jointly promote the development of electric vehicle industry technology Iterate and evolve.

　　3. Core technology, cost control and investment scale have become key factors in the development of lithium battery packs. How to continuously improve quality and technology is the key. The entire power battery industry has entered the fast lane of development, the competitive landscape of the global power battery industry is being reshaped, and industry reshuffle is accelerating. Therefore, if companies want to follow the footsteps of new energy vehicles, they must accelerate technological development and research and development, while controlling costs. Currently, lithium battery packs are still the mainstream product in the market.

　　Although these five types may replace lithium battery packs in the future, this is not a matter of time. After all, lithium battery packs have many advantages. For example, energy storage electrical lithium battery packs have the following characteristics:

　　●Energy density: At the same volume, the energy density of lithium batteries is 3 to 4 times that of lead-acid batteries. The lithium battery pack is smaller and lighter.

　　●Long life: Lead-acid batteries have high requirements on ambient temperature. Under harsh ambient temperatures, the service life is no more than 5 years. The lithium iron phosphate battery pack has a longer service life under the same conditions.

　　●Excellent high temperature performance: The thermal peak of lithium iron phosphate battery can reach 350~500℃.

　　●Fast charging: It can charge and discharge quickly at a high current of 2C. The battery can be fully charged within 40 minutes with a special charger at 1.5C. The starting current can reach 2C.

　　●Safe and reliable: Safety comes from the stability of the cathode material and reliable safety design. Lithium iron phosphate has undergone strict safety tests and will not explode even in violent collisions.

　　●Green and environmentally friendly: It complies with European RoHS regulations and is a green and environmentally friendly battery. Lithium batteries do not contain toxic substances such as lead, mercury, and cadmium.

　　●No memory effect: No matter what state the lithium iron phosphate battery is in, it can be used at any time. There is no need to discharge it completely before charging.

　　●Good performance: strong power, fast charging and discharging.
