Shanghai, China, March 24, 2026 — On the opening day of the 2026 China International Hardware Fair (CIHF), BAK Battery showcased its latest advancements and strategic roadmap in all-tab cylindrical cell technology under the theme “Empowering Every Professional Tool.” From material innovation to structural breakthroughs, and from individual products to a comprehensive matrix, BAK is redefining the power standards for professional-grade tools with its leading all-tab technology.

 

All-Tab Technology: From Lab to Mass Production, Building a Core Moat

As a pioneer in all-tab technology in China, BAK Battery has accumulated over four years of R&D experience, establishing a complete technological moat covering material systems, cell structure, and manufacturing processes. The all-tab 2170-50D2 cell showcased at the exhibition represents the culmination of this technological expertise.

The product pioneers the application of solid-state electrolyte coating technology, effectively suppressing side reactions between cathode materials and electrolyte, thereby enhancing intrinsic safety at the source. Combined with BAK’s proprietary all-tab structural design, the electron transport path is significantly shortened, reducing internal resistance to below 5mΩ and achieving an optimal balance between high energy density and high power output.

“All-tab technology represents a critical direction in cylindrical cell evolution, breaking through the limitations of traditional single-tab and dual-tab structures in high-power applications,” said a Vice President of BAK Battery at the event. “We have not only applied all-tab technology to our 2170 products but have also completed the full line-up across 18-series and 46-series formats. This means BAK is now capable of providing full-scenario solutions for different tool types and power requirements.”

 

Strategic Expansion: Beyond Tools, Targeting High-Potential Application Scenarios

BAK Battery’s technological ambitions extend far beyond power tools. With the continuous performance breakthroughs in all-tab technology, application scenarios are rapidly expanding into high-barrier, high-growth fields such as eVTOL (electric vertical takeoff and landing aircraft), BBU (backup battery units) for data centers, robotics, and drones.

At this exhibition, BAK Battery also disclosed its latest progress in 46-series large-format all-tab cylindrical cells. Featuring a high-nickel + silicon-based system, these products achieve further improvements in energy density while maintaining excellent fast-charging performance and structural stability, meeting the demanding requirements of electric vehicles, energy storage systems, and high-end professional equipment.

“From power tools to eVTOL, from consumer-grade scenarios to industrial applications, BAK Battery’s strategic objective remains clear — building product competitiveness through technological leadership, and expanding market horizons through product competitiveness,” the Vice President added. “We believe all-tab technology will serve as a critical foundation, enabling BAK to achieve breakthroughs across a diverse range of emerging sectors.”

 

Smart Manufacturing Ensures Mass Production Capability

Beyond technological leadership, BAK Battery places equal emphasis on forward-looking manufacturing capabilities. Leveraging fully automated intelligent production lines and an MES-based full-process traceability system, BAK has achieved large-scale, stable production of all-tab cells. The all-tab 2170-50D2 showcased at the exhibition is expected to enter mass production in the fourth quarter of 2026, delivering stable, reliable, and high-quality energy solutions to global customers.
