As we all know, the new market demand for lithium-ion batteries is taking shape very quickly. Lithium ion batteries are currently divided into three parts. The first is consumer electronics. Now, the vast majority of mobile devices, smartphones and laptops have used lithium-ion batteries. The market capacity can be calculated in 10 billion units. The second is the rising demand for electric vehicles. Whether pure electric vehicles or plug-in hybrid vehicles, the current demand has gradually formed. Third, remind colleagues that lithium batteries will be used in the field of energy storage in the future. Its market capacity will be broader than that of electric vehicles, and its market can even be measured by such an output value of trillion.
The demand of electric vehicles and energy storage market has formed a new market space for lithium-ion batteries. At present, a number of enterprises with technical foundation and production capacity are growing very rapidly, and the technical progress of power battery is also very rapid.
Lithium battery is one of the commonly used batteries in electric vehicles, and is being used by more and more new energy vehicles. Although lithium-ion batteries cannot be compared with gasoline in terms of energy density, it is extremely difficult for other battery technologies to reach the level of lithium-ion batteries. Lithium ion batteries cannot be replaced by other batteries in terms of energy density and service life. From lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries to lithium-ion batteries, the energy density has been continuously improving. At present, the lithium batteries equipped with mainstream electric vehicles mainly include lithium iron phosphate battery and ternary lithium battery. Compared with lithium iron phosphate battery, ternary lithium battery is much higher in weight and energy density. In addition, the low temperature resistance of ternary lithium battery in winter is much higher than that of lithium iron phosphate battery. This means that a ternary lithium battery of the same weight has a longer range than a lithium iron phosphate battery. Since there is little room to improve the energy density of lithium iron phosphate batteries, and there is still room for the development of ternary lithium batteries, ternary lithium batteries will become the technical trend of electric vehicles in the future.
At present, the requirements of electric vehicles and energy storage applications require the industrialization of products with safety, high energy density, long life, low cost and considerable mature technology, so as to match the rapid development of these two industries. Now, lithium ion power battery is an excellent choice at present. The broad market demand is also attracting a lot of R & D and manufacturing investment into this industry, which has promoted the rapid development of lithium-ion battery technology, so this industry has developed very fast in recent years. When it comes to power technology, it's very important. Power battery pursues five aspects of performance, safety comes first, and the other two pursues, one is energy density, the other is power density, and then the service life is very important.
