The 18th China International Battery Fair (CIBF 2026) is now in full swing from May 13 to May 15. ACEY is excited to meet customers, partners, and battery industry professionals here at Booth 7T117. As one of the largest battery industry exhibitions, CIBF brings together companies and visitors from around the world. From the moment the exhibition halls opened this morning, the atmosphere has been energetic and busy. At our booth, we are showcasing a range of lithium battery manufacturing equipment and production solutions, including battery sorting machines, testing equipment, welding systems, and battery pack assembly solutions. Many visitors stopped by our booth to discuss battery manufacturing projects, production requirements, and customized solutions with our team. To make on-site communication more comfortable, we also prepared product catalogs, complimentary drinks, and a small meeting area for visitors who would like to have more in-depth discussions with us. It has been a great start to the exhibition, and we are looking forward to meeting more industry friends over the next two days. If you are attending CIBF 2026, welcome to visit us at Booth 7T117.
