The development trend of lithium-ion batteries in the next few years

　　In the next few years, the overall trend of the lithium-ion battery market is improving. In 2020, the output of the lithium-ion battery market will reach 205.33GWh, and the CAGR will reach 41.88% in the next two years. Power batteries and energy storage batteries have become the main growth points under the guidance of global environmental protection policies, and the CAGR will reach 56.32% in the next two years; digital batteries will be driven by the high-end digital battery market, and the CAGR will reach 7.87% in the next two years; In the energy battery field, due to the decline in the cost of lithium-ion batteries in the future, the replacement of lead-acid batteries will gradually accelerate, and the CAGR is expected to reach 35.16% in the next two years.

　　(1) High energy density becomes the future development trend

　　In the future, power batteries will be the largest growth engine in the field of lithium-ion batteries, and the development trend is high energy density and high safety.

　　(2) 6μm ultra-thin lithium battery copper foil becomes the focus of mainstream enterprise layout

　　At present, lithium battery copper foil is mainly 8μm. In order to improve the energy density of lithium-ion batteries, thinner 6μm copper foil has become the center of gravity of the layout of mainstream lithium battery copper foil manufacturers.

　　(3) The production capacity of lithium battery companies has expanded significantly

　　New energy vehicles will advance faster because of environmental protection policies, and the cost of power batteries needs to be further reduced to improve the market competitiveness of new energy vehicles.

　　(4) High-end digital batteries have become the main growth point of the lithium-ion battery market

　　The high-end digital battery field, represented by flexible batteries, high-rate digital batteries, and high-end digital soft packs, is driven by market segments such as wearable devices, drones, and high-end smartphones, and has become a relatively high-growth part of the 3C digital battery markets.
