Copper foil is an important basic material in the field of lithium battery and electronics. Industrial Copper Foil can be divided into calendered copper foil and electrolytic copper foil.

Electrolytic copper foil is mainly divided into lithium copper foil and standard copper foil. Copper foil can be divided into lithium copper foil and standard copper foil according to different application fields. The thickness of lithium copper foil is generally 6 ~ 20 m double-light copper foil, which is used for lithium batteries in power, consumer and energy storage fields. Standard copper foil is mainly used in electronic information industry, such as low power printed circuit board (PCB) . In 2019, domestic sales of lithium copper foil and standard copper foil accounted for 31.3% and 68.7% respectively, according to China electronic copper foil information network.

At present, the domestic new energy automobile industry is in the transition period from policy-driven to market-driven. New models with high performance-to-price ratio are the key factors to stimulate the spontaneous demand of the market. Both domestic manufacturers and joint ventures have accelerated the pace of the introduction of new models, high performance-to-price ratio of new models launched intensively, lithium-ion battery demand is also increasing.

Lithium batteries are mainly divided into power batteries, energy storage batteries, consumer batteries and other types of batteries (including power tools, chargers and other low-end lithium battery products) , 8 M copper foil consumes 830 ~ 1000 T/GWH, 6 m copper foil has lower mass per unit area and less mass consumption under the same area. Suppose that the demand for 8 m copper foil for 1 GWH ternary battery and lithium iron phosphate battery is 850 t and 950 t respectively, the demand for 6 m copper foil is 650 tons and 750 tons respectively.

6 M Copper Foil permeability assumption, the main demand for domestic power battery enterprises, overseas enterprises are still mainly 8 m copper foil, the permeability is expected to be 5% , 10% , 20% in 2020 ~ 2022, by 2025 the permeability of 50% ; In the domestic power battery field, the permeability is estimated to be 60% , 80% , 90% in 2020-2022, and 100% in 2025. The field of energy storage and consumer batteries is still dominated by 8 m copper foil, with an estimated permeability of 0% .

From 2020 to 2022,1.1 million, 1.77 million and 2.295 million new energy vehicles are expected to be sold in China. The demand for power batteries is 60.43 Gwh, 102.73 Gwh and 140.14 Gwh, and the global demand for power batteries is 130.45 Gwh, 212.88 Gwh and 05.63 Gwh, respectively. By 2025, the domestic and global power battery demand is 329.41 Gwh, 771.07 Gwh, and the average compound growth rate from 2020 to 2025 is 40.4% and 42.7% respectively.

Global demand for lithium copper foil is expected to reach 768,200 tons by 2025. The global demand for lithium copper foil from 2020 to 2022 is estimated to be 212,700 tons, 296,500 tons and 387,500 tons respectively. The global demand for lithium copper foil from 2025 will be 768,200 tons, and the annual compound growth rate will be 29.3% from 2020 to 2025.

Copper wire price: 2020 by the impact of the epidemic, copper prices are expected to decline in 202043,000 Yuan/ton (excluding tax) , assuming 2021-2025 stable at 46,000 Yuan/ton (excluding tax) . Processing cost forecast: It is estimated that the processing cost of 6M copper foil will be 49,000 Yuan/ton, 45,000 Yuan/ton and 43,000 Yuan/ton respectively from 2020 to 2022, and 37,000 Yuan/ton in 2025 It is estimated that 8 m copper foil processing costs will be 25,900 Yuan/ton, 24,800 Yuan/ton and 24,100 yuan/ton respectively from 2020 to 2022, and 22,700 Yuan/ton in 2025.

The global lithium copper foil market is expected to reach 58 billion yuan in 2025, with an average annual compound growth rate of 30.6% from 2020 to 2025. According to the calculation, the global market space for lithium copper foil is 15.2 billion yuan, 22.3 billion yuan and 29.2 billion yuan from 2020 to 2022, and is expected to reach 58 billion yuan by 2025. The annual compound growth rate will reach 30.6 percent from 2020 to 2025. Among them, 6m lithium copper foil market space is expected to reach 30.4 billion yuan in 2025, accounting for 52% of the global lithium copper foil market space, 2020 ~ 2025 average annual compound growth rate of 64.9% .
