Impressive Launch of BAK PRO-M High-Safety Battery: Providing a Comprehensive Safety Solution for Short-Distance Travel

On February 25th, BAK Battery officially launched its new PRO-M high-safety battery series. Featuring high safety, strong power, wide temperature range, and long endurance, this battery brings a more reliable and efficient energy solution to the short-distance travel market, marking another major breakthrough for BAK in battery safety and performance.

Hundred-Billion-Dollar Market: Surge in Demand for Short-Distance Travel

With the growing global awareness of environmental protection and worsening urban traffic congestion, short-distance travel has become increasingly popular, particularly in the booming two-wheeler electric vehicle market. In China, the electric two-wheeler market has doubled from 2019 to 2024, surpassing the hundred-billion-yuan mark. This growth is driven not only by supportive policies but also by rising consumer demand for green travel solutions.

The global market is showing similarly strong performance. According to Market Research Future, the global two-wheeler electric vehicle market is projected to exceed $100 billion by 2030, with a compound annual growth rate (CAGR) of 34.57% from 2022 to 2030. In response to this market trend, BAK Battery, drawing on years of experience in the short-distance travel sector, has launched the new generation PRO-M high-safety battery to meet the urgent market demand for high-safety and high-performance batteries.

Dual Innovation in Materials and Processes: Unfazed by Nail Penetration Challenges

With the implementation of GB43854-2024 "Safety Technical Specifications for Lithium-Ion Batteries for Electric Bicycles," safety performance requirements have been further enhanced, particularly with the mandatory nail penetration test for individual cells. BAK Battery believes that improving safety performance is the core demand in the light-power sector.

The PRO-M high-safety battery achieves exceptional safety performance through innovations in both materials and processes:

• High-Temperature Resistant Composite Cathode Material: Maintains structural stability under high temperatures to enhance battery safety.
• Composite Coating Separator: Improves thermal resistance to prevent thermal runaway.
• Highly Stable Electrolyte: Effectively suppresses interfacial side reactions, extending battery lifespan.

Additionally, BAK has optimized production processes such as slurry mixing and coating to produce high-quality electrode sheets, significantly improving battery consistency. As a result, the PRO-M high-safety battery not only passed rigorous nail penetration tests but also boasts high-rate charge and discharge capability, long cycle life, and superior safety.

Comprehensive Performance: Strong Power, Wide Temperature Range, Long Endurance

While ensuring high safety, the PRO-M high-safety battery also offers the following performance advantages:

• Strong Power: Utilizes a composite conductive agent and highly conductive new foil material, reducing impedance by 33% and increasing discharge capability to 5C.
• Wide Temperature Range: Equipped with a temperature-adaptive electrolyte and specially designed electrode sheets, supporting an ultra-wide operating temperature range of -30℃ to 70℃.
• Long Endurance: Adopts high-voltage composite cathode material and new pressure-resistant foil, increasing energy density by 17%.

PRO-M 18650 and 21700 Models Officially Released

The newly launched PRO-M high-safety battery includes two models, 18650 and 21700, both meeting the safety performance requirements of GB43854 and GB40559:
