SHENZHEN, China, May 17, 2025 — The 17^th China International Battery Fair (CIBF 2025) was held in Shenzhen from May 15-17. BAK Battery presented its three primary product lines: cylindrical, polymer, and prismatic batteries.

BAK Cylindrical Battery: “Energy Capsules” Continue to Evolve, Powering Innovation in End-User Products

Leveraging over two decades of experience in cylindrical batteries, BAK Battery has established a comprehensive product platform featuring high capacity, high power, and high safety across its cylindrical series. Based on years of research into tabless technology, BAK Battery has pioneered a tabless cylindrical battery matrix, encompassing 18, 21, and 46 cell series. Compared to conventional cylindrical batteries, this novel structure significantly improves performance metrics such as discharge capability, durability, charging speed, and cycle life.

Addressing safety concerns for electric two-wheelers, the new national standards impose strict safety requirements. The BAK PRO-M high-safety battery not only conforms to the GB43854-2024 and GB40559-2024 safety performance standards but also exceeds the industry’s most demanding nail penetration test. Its advantages, including a wide temperature range and long cycle life, ensure an exceptional user travel experience.

BAK Polymer Battery: Accelerating the Application of Solid-State Battery

Solid-state batteries, considered the next-generation power battery technology, are rapidly moving toward industrialization. Using a new technology approach, BAK intends to launch its 390Wh/kg solid-state battery product by the close of 2025, boasting a cycle life of 800 cycles. This product is designed for high-performance applications demanding superior battery capabilities, such as explosive-proof safety equipment, vehicle battery swapping, and eVTOL applications. Currently, multiple BAK solid-state battery products have passed the nail penetration test and are already utilized in explosive-proof safety equipment.

Alongside solid-state batteries, polymer batteries are another key highlight of BAK’s exhibition. As a leading global supplier of consumer-grade polymer pouch lithium batteries, BAK provides a wide array of products characterized by high power, fast charging, high energy density, and a wide temperature range. These products reliably power mobile phone battery swapping, power banks, and smart home devices, perfectly aligning with the evolving needs of AI-driven electronic product upgrades.

BAK Prismatic Battery: Embracing a Green Future and Charting a Path Toward High-Quality Development

As the energy storage sector transitions from “scale expansion” to a new phase of “high-quality development,” large-capacity cells have become the central point of next-generation technological innovation. Against this backdrop, BAK Battery is continuously advancing material innovation and process enhancements, introducing its 688Ah prismatic cell. By lowering the cost per Wh, BAK is consistently strengthening its competitive position in the clean energy industry.

Mr. Liu Zhibo, Executive Vice President of BAK Battery, stated, “As one of the earliest pioneers in China’s lithium battery industry, BAK has witnessed and contributed to the evolution of China’s lithium sector from a follower to a global industry leader. Today, as the world is at a crucial juncture in energy transition, BAK remains dedicated to innovation, continuous investment in R&D, and the delivery of high-quality products and solutions, enabling synergistic growth across the value chain and contributing to a greener, low-carbon, and sustainable future.”
