-China’s first overseas all-polar ear production line landed in Julin, Kedah state, opening a new chapter in globalization strategy
on March 26, 2026, the commissioning ceremony and global partner conference of Haisida Malaysia all-polar ear base were successfully held, and the leading battery manufacturing base in Julin, Kedah state, Malaysia was officially put into production. The move marks the successful landing of China’s first overseas all-pole ear cylindrical battery large-scale production line , which is not only a major milestone in Haisida’s globalization strategy, but also demonstrates to the global market Haisida’s firm determination to cultivate the new energy track and accelerate the global layout of the supply chain. On the day of the commissioning ceremony, local dignitaries such as the Executive Councillors of Kedah State, the Malaysian Interior, the Kuhlin City Council, and the Kuhlin Branch of the Royal Customs Bureau of the Malaysian Investment Development Agency (MIDA) were invited to gather together with strategic customers and partners from around the world to witness this historic moment.
Comply with macro trends, deeply ploughing the global layout of” long-termism “
Facing the irreversible trend of global green energy transformation and the inevitable choice of supply chain globalization, Haisida has settled its strategic overseas production base in Malaysia. Mr. Zhou Wen, Chairman of Haisida, said in a speech at the commissioning ceremony: “The choice of Kulim Malaysia is based on a comprehensive judgment of global trends, location advantages and a high-quality business environment. This factory is not only Haisida’s overseas manufacturing base, but also a platform for our close cooperation with global customers and a long-term commitment to the development of Malaysia’s industry. We will adhere to localized operations and long-term doctrine, with international first-class quality standards, to provide global customers with absolutely competitive power solutions. “
A new generation of 21700-50PS was released. All-pole ear technology broke the industry performance ceiling
as the core highlight of this production ceremony, haisida has released a new generation of all-pole ear batteries-INR21700-50PS. This all-round battery core with a rated capacity of 5.0Ah has successfully pushed the all-pole ear technology from the laboratory to a new height of large-scale and intelligent mass production. This is an all-round battery cell that takes into account high capacity, high power and long life, and finally achieves 3 major technological breakthroughs, 4 core highlights and 5 major application areas.
this cell has realized the bottom innovation in material system and structure design: through the jointly developed Ni90 + high-energy positive electrode, a new generation of silicon carbon (SiC) fast charging negative electrode, and a revolutionary “point-line-surface” three-dimensional electronic conductive network, the intergenerational leap in cell performance has been realized.
its four core advantages include:
extreme internal resistance and explosive force: internal resistance plummets to ≤ 3mΩ (more than 70% lower than traditional), supports instantaneous pulse discharge up to 250A(50C), and perfectly matches equipment requiring instantaneous extreme power.
the wide temperature range that breaks through the boundary: it can discharge stably in the extreme environment of -40 ℃ to 80 ℃, completely breaking the battery application forbidden zone in high latitude cold zone and high temperature outdoor operation.
efficient and fast charging: supports 3C fast charging (charging to SOC80% in 15 minutes), removes anxiety about electricity consumption, and greatly improves the efficiency of industrial and outdoor operations.
ultra-long cycle: in severe cycle test, the battery can achieve 1000 cycles under 30A high-rate discharge. compared with multi-pole-ear battery, the cycle life is improved by more than 1 times, while supporting 50A and 70A high-rate cycles. 
enabled the whole scene to draw a blueprint for high-end intelligent manufacturing
at the end of the ceremony, guests were invited to visit the world’s leading all-polar ear production line at haisda malaysia base. From the high-precision manufacturing of the front pole piece to the highly automated slitting and assembly workshop, Haisida’s strict quality control and extremely intelligent manufacturing ability have won high praise from the politicians present and customers around the world.
relying on comprehensive and strong performance support, haisida 21700-50PS batteries will fully cover five core application fields such as high-end electric tools, garden tools, industrial robots & AGV, AIDC, eVTOL, etc.
“Production is a starting point, not an end point. “Haisida will use its Malaysian base as a new engine, continue to deepen the field of small power batteries, continue to develop innovative products with high performance and high cost performance, and work with global partners in a lasting, stable and trustworthy manner to draw a new blueprint for the global green energy era.
