recently, penghui energy, as a leading cylindrical battery enterprise in the industry, was invited to participate in the 2026 starting point lithium battery cylindrical battery technology forum, published the theme report “embrace change with innovation”, and discussed the technological change and market trend of small cylindrical battery with the industry. Facing the background of the transformation of global energy structure, the popularization of electrification, the rapid rise of intelligent equipment and low-altitude economy, Penghui Energy clearly put forward: “The small cylindrical pattern in the next three years has the final say.”
2026 is the first year of the 15th five-year plan. the policy of new quality productivity is reshaping the industrial pattern. the state has clearly included low-altitude economy and intelligent robots into the emerging pillar industries, with its core advantages of high standardization, controllable manufacturing cost and excellent safety, the small cylindrical battery is becoming the invisible engine of “electrification of all things”, and the small cylinder with full polar ear is the key direction to lead the technology iteration.
all-polar ear reconstruction technical barriers, small cylinder enters the era of high power and high safety
in the forum, penghui energy pointed out that from BBU to two-wheeled travel, from portable energy storage to intelligent robots, the terminal scene of small cylindrical batteries is undergoing unprecedented diversified fission, and small cylindrical batteries are in a golden track with high growth and high certainty. Facing the intelligent era, Penghui Energy believes: “Multi-scene extension is driving the small cylindrical battery technology to break through in the direction of differentiation and refinement on the basis of all-pole ears, and to meet the needs of end customers with high power, high safety and precision.”
in the technical research and development of small cylindrical batteries, penghui energy focuses on all-pole ear technology and comprehensively reconstructs the core performance of small cylindrical batteries. Penghui Energy believes: “The traditional unipolar ear is like the’ sheep intestine trail’ in the current, while the all-polar ear technology creates a current highway-lower internal resistance, better heat dissipation, stronger power and greatly improved safety.” This is not a simple performance optimization, but a structural revolution in the field of small cylinders.
Penghui Energy’s new all-pole small cylindrical battery 21700 series, with innovative all-pole structure design, and with high nickel ternary positive electrode, new silicon carbon negative electrode, patented electrolyte and three-dimensional conductive network, to achieve a leap-forward improvement in rate performance.
passed authoritative acupuncture test: 21700 full series of high safety hard core strength
at present, penghui energy has formed a complete full ear product matrix of 21700-4000mAh, 5000mAh and 6000mAh. many models have passed acupuncture test by third-party organizations, and their safety performance has obtained authoritative certification, providing reliable safety guarantee for terminal applications.
relying on technological innovation, penghui full-ear small cylindrical battery 21700 series has achieved three breakthroughs:
· ultra-fast charging: supports 3C charging, 20 minutes of fast full charging, and efficiently adapts to high-frequency usage scenarios;
· high power: supports 15C continuous discharge and 36C pulse discharge to easily meet the power requirements of high-power equipment;
· Wide temperature range: work stably in the environment of -40 ℃ to 70 ℃, and expand the application edge of complex scenes such as extreme cold and high temperature.
Excellent performance makes high-power small cylinders an ideal power choice for power tools, garden machinery, vacuum cleaners, portable energy storage and other scenarios.
full-scene depth enabling: helping BBU, robots and low-altitude economy to develop with high quality
penghui full-ear small cylindrical products fully cover mature high-power scenes such as electric tools and portable energy storage, and accelerate the layout of cutting-edge tracks such as mechanical dogs, industrial robots, service robots, unmanned aerial vehicles, eVTOL low-altitude economy, etc, the development of BBU and intelligent equipment industry is deeply empowered with high security and high power characteristics.
Small cylindrical battery has entered the era of full pole ears! In the future, Penghui Energy will always adhere to innovation and embrace the future, with higher safety, higher power, higher capacity of all-pole ear products, deep energy BBU, robots, low-altitude economy, power tools and other fields of end-customer product changes, and jointly open a new era of small cylindrical batteries.
