In recent years, with the expansion of electric power drive systems to fields such as automobiles, cruise ships, cargo ships, rail transit, and agricultural machinery, China’s power battery industry has developed rapidly, and its installed capacity of power batteries has maintained a global lead. Against this background, the country has successively introduced multiple measures to encourage and support the development of the power battery recycling industry. It is expected that by 2025, the domestic retired lithium-ion batteries will reach one million tons, and by 2030, it will reach three million tons.
SUMEC International Technology Co., Ltd. (hereinafter referred to as “SUMEC-ITC”) is the agent for direct sales of BHS-Sonthofen (hereinafter referred to as “BHS”), a German century-old brand that specializes in the recycling and disposal technology of lithium-ion power batteries. Its waste lithium battery recycling and processing technology of “integrated crushing + low-temperature vacuum drying + combined sorting” is at the forefront internationally.
High-end intelligent technology
shines at the CIIE!
In 2022, BHS joined forces with Yongcheng Trading Co., Ltd., a subsidiary of SUMEC-ITC, to officially debut at the 5th China International Import Expo. The advanced processing technology and technical highlights attracted the attention and consultation of many professional visitors. Among them, two corporate customers who learned about BHS’s waste lithium battery recycling and processing technology signed a letter of intent for cooperation on-site.
BHS is highly respected by consumers
due to its three major processing technologies!

Crushing Technology – Integrated Safe Crushing
The BHS crushing system is a sealed and integrated crusher that provides safety protection. It is suitable for both battery modules and battery cells. Depending on the feed state, it can be divided into two-stage crushing or single-stage crushing. BHS’s self-developed and designed cutting and crushing tools can effectively disintegrate battery materials. Due to the crushing of the shell and the mutual friction between the materials during the crushing process, the black powder can be effectively released, laying the foundation for fine processing in downstream processes.
Drying Technology – Low Temperature + Vacuum
The average temperature during the drying process is 100-120℃. By using the “low-temperature + vacuum” method, the production of toxic gases (HF) can be greatly suppressed. The electrolyte that evaporates at low temperatures is recovered through two-stage condensers at the back end. This process not only suppresses the residual organic matter in the output but also avoids the generation of oxide impurities and toxic gases at high temperatures.
Vacuum low-temperature drying can prevent the generation of impurities due to oxidation and has no thermal decomposition. Therefore, the physical, chemical, and biological properties of the material after drying are basically unchanged. The residue generated during the recycling process will not produce slag deposition as in the pyrometallurgical process, resulting in higher recovery rates, lower energy consumption, shorter time, and a smaller carbon footprint.
Sorting Technology – Multi-stage Combined Sorting
Through multi-stage screening processes such as circular shaking multiple-level sifter, zigzag sifter, and air table sifter, the waste is first separated into different particle size levels. Then, heavy materials are removed again, and the remaining lightweight materials are finely crushed. According to the particle size and density indicators, black powder, copper, aluminum, and plastic are sorted and extracted step by step to ensure the purity and precision of the final extract.
Currently, BHS has delivered five stable lithium battery recycling and processing lines worldwide. In May 2022, it also released a “Lithium-ion Battery Recycling Technology Whitepaper” to showcase its unique and leading technology. Facing the Chinese market, BHS will continue to vigorously promote new process research and development and technology upgrades according to industry changes, and establish an international high cost-effective processing line suitable for China’s characteristics.
