Driven by the two wheels of policy and market, lithium battery technology has developed rapidly. In recent years, the lithium battery pack industry has huge development potential and demand is growing rapidly. Driven by both policies and market, lithium battery technology will reach new highs.

　　1. The development trend of automobiles has become a consensus

　　Intelligent and driverless cars are based on electrification, and we are currently at a critical stage of electrification development. From our country's perspective, new energy vehicles have become one of my country's top ten key pillar industries and are supporting development. The sales proportion of new energy vehicles is growing rapidly. Since 2012, most of the growth has come from electric buses due to the development of electric logistics vehicles.

　　Another big field of new energy vehicles is passenger cars, which have accumulated rapid growth momentum in recent years. New energy vehicles have good rights of way, especially electric scooters and online ride-hailing vehicles, which have formed an obvious demand situation. If batteries can meet these needs, it should be said that this market will develop rapidly. Everyone’s expectation is that there will be explosive growth this year.

　　2. Policies and specifications for lithium ions

　　As the core component of new energy vehicles, power lithium-ion batteries have received a lot of support and regulation from many national policies. The editor here will talk about a major policy, our policy specification for lithium ions, the price is 8 yuan per kilogram. Under market demand and policy planning, lithium-ion batteries have entered a rapid development path technically. The overall market demand for new energy lithium-ion batteries requires the safety and reliability of batteries. On the basis of safety and reliability, lithium-ion batteries meet the personalized needs of different application fields through technological innovation.

　　3. Rapid development of lithium battery packs

　　During the period of rapid development of lithium battery packs, the biggest pain point in its technological development, or the point that needs to be broken through, is the balance between performance and cost. It is a very big challenge to have both good performance and competitive product advantages. Rapid development is a big challenge.

　　To solve this challenge, three contradictions must be resolved. One is that the energy density is safe; the other is the energy density and power density, which require high energy and fast charging; the third is high-temperature performance and low-temperature performance. For chemical systems, this is A contradiction is a very big challenge. The development of power lithium-ion is constantly balancing these contradictions. Therefore, if lithium ion is to develop forward, it must first take into account high and low temperature and fast charging performance. On this basis, we can improve our energy density and increase safety performance. Therefore, the development of technology depends on technological breakthroughs in all aspects of the battery's positive and negative electrodes.

　　There are two types of fast charging: one is 40, which can charge 80% to 90%, and its effectiveness is comparable to the speed of refueling; the other is 80, which is equivalent to 3-5 minutes of charging and can charge to 70%. to 80%, meeting the cruising range of 100 kilometers.

　　Driven by the two wheels of policy and market, lithium battery pack technology is developing rapidly, and the realization of relevant technical indicators set by the country is expected.
