When talking about RFID power, people generally think of the application in shoes and clothing, retail, logistics and other scenarios first. It is true that most of the market for RFID comes from the retail of shoes and clothing. The application is relatively small, but with the development of technology, the expansion of industry digital demand and the promotion of related policies, RFID has also begun to shine in other fields, such as the new energy industry.

According to the EU’s “New Battery Law”, starting from 2026, all newly purchased electric vehicle (EV) batteries, light vehicle (LMT) batteries and large industrial batteries must have a battery passport to enter when a single battery exceeds 2 kWh European market. On January 18, at the World Economic Forum in Davos, Switzerland, the Global Battery Alliance (GBA) released the battery passport proof-of-concept results for the first time.

The battery passport prototype released this time records the full life cycle data of the three batteries, including manufacturing history, chemical composition, technical specifications, carbon footprint, etc.

At the Power Battery Forum of the China Electric Vehicle Hundred People’s Association held on April 2, Liang Rui, vice president of the domestic battery company Xinwoda, pointed out that “the battery passport is essentially a data management system for the battery life cycle, which will provide a comprehensive solution for the global battery value chain. Bring higher transparency.”

“The source of battery materials, technical specifications, chemical composition, manufacturing process, carbon footprint, etc. must be displayed in the disclosed information, which will be a very large data system.” Liang Rui said, in his It seems that the battery passport revolves around two lines, one is the quality management of the battery’s full life cycle, and the other is the carbon management of the battery’s full life cycle.

RFID Power to Cut Through the Big Cake of New Energy

The latest data released by SNE Research, a South Korean battery market research organization, shows that in 2022, the global installed capacity of power batteries will reach 517.9GWh, a year-on-year increase of 71.8%. Among the top 10 companies in terms of vehicle loading, Chinese power battery companies occupy 6 seats, with a total market share of 60.4%.

CATL, as the world’s largest power battery supplier, continues to maintain an absolute advantage in the power battery market. In the future, the lithium battery industry will still maintain a good growth momentum, which will bring tens of millions or even billions of RFID tag usage and a million-level reader-writer demand every year.

Not limited to power batteries, RFID on photovoltaic cells is also promising. As a safe and clean green energy, photovoltaics have been closely watched and valued by people.

Since the overall production process of the photovoltaic industry is relatively complicated, the production process of solar cells includes: silicon wafer inspection, surface texturing and pickling, diffusion junction, phosphorus silicon glass removal, etching and pickling, anti-reflection coating, Screen printing and rapid sintering, etc., need to track and trace the production process to ensure production quality.

With RFID technology as the core, in the manufacturing process of the product, identification equipment is installed in each process to identify product identification, and through the automation equipment As well as the docking of the manufacturing system, the technical status information of the product manufacturing process can be obtained in real time, and the product quality can be monitored in real time.

In 2022, my country’s photovoltaic cell shipment output will be about 318GW, and the capacity of photovoltaic cells will be calculated as 300W, which will bring demand for 100 million-level RFID tags every year. In terms of the volume of industrial readers, there are 200-300 production lines for domestic photovoltaic cells, and the market capacity of industrial readers in the photovoltaic industry is one million units.

Why does RFID have More Potential than other Recognition Technologies

At present, barcodes and QR codes are the most widely circulated in the market. According to industry experts, they can be replaced by RFID in theory, because in more scenarios, RFID is more suitable than barcodes and QR codes, which means RFID It is different from the technology of bar code and two-dimensional code.

According to the characteristics of RFID technology, the advantages of RFID over barcodes and two-dimensional codes are reflected in:

  • Large storage capacity, fast read and write speed, high security;
  • Longer recognition distance;
  • More flexible application;

Data encryption can be performed by software;

  • Multi-object recognition, repeated use, strong penetration.
  • Unmanned without contact
  • Long life, can adapt to more complex application environment

Therefore, RFID has greater potential for many scenarios, especially high-end manufacturing scenarios such as new energy. In the production process of new energy products, refined management, guarantee of unmanned yield rate, and improvement of production efficiency have more dimensions. It has great advantages and has the conditions to be widely used.

Summary and Outlook

In market demand amplification and the driven by the policy, RFID in the prospect of the new energy industry, of course we should also see the RFID in the new energy industry is still in the application, the understanding of industry scene and to adapt to the environment technology upgrade also need industry constantly grinding, to serve the new energy industry customers, maintain good reputation, is the prerequisite of industry application popularization.
