Looking back at over a decade of power battery development, prismatic, pouch, and cylindrical formats each have their own suitable use cases and evolutionary paths; diverse technical routes will continue to coexist.
This concept is rooted in three intrinsic advantages of large cylindrical cells:
Standardization is key to covering diverse scenarios. A single 4695 large cylindrical cell model is already compatible with 37 vehicle models. From compact A-class cars to full-size SUVs, and from commercial vehicles to energy storage applications, a single cell can meet a wide range of needs. Moreover, uniform specifications eliminate the need for frequent production line retooling and calibration, laying the groundwork for AI-driven smart manufacturing to achieve PPB-level yield rates.
Zero expansion is a highly distinctive feature of large cylindrical cells. Their circular cross-section offers inherent mechanical advantages that effectively suppress expansion, ensuring consistent cell dimensions throughout the entire lifecycle and rendering complex system-level stress management a thing of the past.
High strength is another major highlight. The steel casing is more than six times stronger than aluminum casings. Combined with a design that separates gas and electrical components, the cell triggers directional pressure relief within 4 milliseconds and releases 50% of its heat in 5 seconds, keeping the temperature rise of adjacent cells under 70°C. This structural foundation ensures system safety, providing a secure platform for the application of high-energy-density materials.
Validation across all scenarios and "in-situ upgrades" highlight the platform's value.
Large cylindrical battery technology continues to evolve in areas such as high energy density, high power output, fast charging, and long cycle life, achieving solid progress: products with 260Wh/kg and 280Wh/kg ratings have already been installed in vehicles at scale, with the 280Wh/kg version enabling a 1,000km range in mass-produced models; the 300Wh/kg product is entering the vehicle mass-production stage this year; and the 320Wh/kg product is pioneering applications in the low-altitude economy sector.
Even more significant is the platform value derived from "in-situ upgrades." Using the same cell—without altering production lines or structural designs—manufacturers can simply switch the chemical system to iterate battery packs with varying capacities, such as 80kWh, 98kWh, and 114kWh. This allows automakers to upgrade performance across the product range—from entry-level to high-end models—without modifying the vehicle structure, drastically reducing validation cycles and R&D costs. Underpinning this capability is EVE Energy’s "3+2" chemical system strategy and a manufacturing foundation capable of a daily output of 5 million cells. Currently, EVE Energy’s large cylindrical batteries are being supplied for various vehicle models—including those from BMW and Hongqi—as large-scale adoption steadily advances.
Beyond automotive applications: exploring broader possibilities for large cylindrical batteries.
The potential for large cylindrical batteries extends far beyond passenger vehicles. Leveraging its technical expertise in high-power cylindrical battery applications, EVE Energy has expanded the use of large cylindrical cells into sectors such as HEVs and 12V/48V systems, while continuously pushing the boundaries of ultra-high discharge rates (reaching 100C)—notably, race cars equipped with EVE Energy batteries achieved outstanding results in top-tier competitions this year.
Looking ahead, the application landscape for large cylindrical batteries is becoming increasingly clear: spanning from two-wheeled mobility to four-wheeled vehicles, from robotics to the low-altitude economy, and from competitive racing to diverse mobility scenarios. With a platform-based capability defined by the concept of "one cell, infinite applications," large cylindrical batteries are permeating every corner of the electrification landscape.
