Lithium copper foil Application:

For example, for copper foil, some time ago the article also shared the industry space and representative companies of copper foil. Today, let's talk about it in detail. Copper foil for lithium battery is the main material for collecting the positive material of lithium battery. Its function is to collect the current generated by the active material of the battery, so as to output more current. It is located in the upstream of the lithium battery industry chain, and together with cathode materials, aluminum foil, anode materials, diaphragms, electrolyte and other materials (such as conductive agents, packaging materials, etc.), it forms the battery cell of lithium batteries, Then the battery cell, BMS (battery management system) and accessories are packaged to form a complete lithium battery pack, which is used in new energy vehicles, electric bicycles, 3C digital products, energy storage systems and other downstream fields. From the perspective of cost proportion, it accounts for 5% of the total cost-

Lithium battery copper foil is superior to PCB copper foil:

It should be emphasized that the main attraction of copper foil is lithium copper foil, which is more expected than PCB copper foil. It can also be seen from the compound growth rate in the past five years that the PCB copper foil is 7.5%, while the lithium copper foil is 19.9%, and the output growth rate of lithium copper foil is much faster than that of PCB copper foil. Then companies related to lithium battery copper foil will naturally benefit a lot.

In terms of demand:

1. The rapid development of the new energy vehicle industry is the main driving force for the growing field of lithium battery power batteries. From 2015 to 2020, the global CAGR of new energy vehicles reached 41.6%, and the sales volume in 2020 was 3.125 million. From 2015 to 2020, the CAGR of new energy vehicles in China reached 29.2%, and the output of 1.366 million vehicles in 2020. Under the combined effect of many factors, such as the rapid increase of new energy vehicle consumption, the increase of penetration rate, the abundance of models, and the ban on sales of fuel vehicles, the subsequent new energy vehicles will continue to grow at a high speed, driving the rapid increase of power battery installed capacity.

2. Electrochemical energy storage: According to the optimistic prediction of CNESA at the beginning of the year, the newly added electrochemical energy storage capacity in China will reach 3.3GW in 2021, and the newly added energy storage capacity in China will exceed 10GW in the first half of 2021, with a year-on-year growth of more than 600%+, which is much higher than expected. In addition, according to the conservative prediction of CNESA Research Department, with the rapid popularization of the "photovoltaic+energy storage" application mode nationwide, the cumulative scale of electrochemical energy storage will increase by 57.4% from 2021-2025, and is expected to reach 35519.1MW in 2025. From the perspective of the growth rate and future planning of the energy storage industry in 2021, it will maintain rapid growth in the next five to ten years, and lithium ion batteries will dominate the global electrochemical energy storage market. In the future, the proportion of renewable energy represented by photovoltaic and wind power will further increase, and the demand for lithium ion energy storage will be stronger.
