Lithium ion battery market pattern and lithium ion battery energy density -Lithium - Ion Battery Equipment
Lithium ion battery manufacturers interpret the lithium -ion battery market structure and energy density of lithium ion battery. In recent years, my country's power lithium -ion batteries have developed rapidly, and it is important to support the strong support of national policies for the new energy vehicle industry. my country's new energy vehicle industry has maintained rapid development. With local advantages, domestic lithium -ion -powered lithium battery companies' shipments have also increased significantly. The following lithium -ion battery manufacturers interpret the lithium -ion battery market pattern and energy density of lithium -ion battery.
Lithium -ion battery market pattern
In recent years, my country's new energy vehicle industry has maintained rapid development. With local advantages, domestic lithium -ion -powered lithium battery companies have also increased significantly. According to statistics, in the first four major Chinese electric vehicle lithium -ion power lithium batteries in 2018 The company's shipments accounted for 63%. According to the classification standards of the field structure, the centralized oligopoly occupied market, and the concentration was relatively high.(Lithium - Ion Battery Equipment)
my country's lithium -ion battery market has maintained a high -speed rise, and it is driven by the high -speed rising of the power lithium battery market. In 2018, the output value of the top five companies in my country's power lithium battery market accounted for 71.60%, and the market concentration further increased. With the gradual implementation of national policies, and the improvement of the production technology of lithium -ion battery in the future, decline in cost, improvement of the popularization of new energy vehicles and supporting facilities, the demand for power lithium batteries of new energy vehicles will increase, thereby promoting the lithium -ion battery industry Expansion of the overall market size.
From the perspective of domestic lithium -ion battery applications, the rapid development of power, energy storage, and 3C has become an important driving force for the development of the lithium -ion battery industry. Among them, the rise of 3C lithium -ion batteries has slowly increased; the proportion of the market has continued to decline; the lithium -ion battery has increased the infiltration rate of lithium -ion batteries in electric bicycles due to the steady increase in electric vehicles, and the market proportion has increased rapidly; energy storage power stations The pace of construction has accelerated, and the gradual promotion of lithium -ion batteries in the field of energy storage batteries in mobile communication base stations, the market proportion of energy storage lithium -ion batteries is from scratch.
The development of the global lithium -ion battery industry has four major characteristics: first, the driving effect of the power lithium battery is displayed; the second is that the focus of industrial development has further shifted to our country; the third is that the pace of technological innovation has gradually accelerated; and the fourth is that industrial integration has continued to strengthen. The development of various countries has different development, Japan's growth rate has begun to recover, South Korea's growth rate has declined significantly, and my country has maintained a steady rise.
Lithium ion battery energy density
When the same energy consumption remains unchanged and the volume and weight of the battery pack is strictly limited, the single maximum driving mileage of new energy vehicles depends on the energy density of the battery.
People in the industry said that the current single energy density of the ternary lithium -ion battery is close to the limit, and it is difficult to make a big breakthrough. To further increase the energy density of the ternary lithium ion battery, it is necessary to further increase the proportion of nickel in the battery. However, after the proportion of nickel in the battery is increased, due to the poor thermal stability of high nickel, the thermal reaction inside the battery will be very violent, and the safety problem is worrying.
Relying on the battery technology route of Sanyuanli, the energy density of the power lithium battery must achieve the goal of 350Wh/kg, which is very difficult. Therefore, the industry hopes to rely on solid -state batteries to further increase battery energy density.
In terms of monomer, the advantages of ternary soft bags are indeed obvious. Especially when the quality and energy density is compared, the soft bag battery is packaged in the structure in the structure. It is 40%lighter than the steel shell lithium -ion battery with the same capacity than the same capacity, and 20%lighter than the aluminum shell lithium -ion battery.
