4680 Battery Cell Free Sample Available | CNS BATTERY
The electric vehicle and energy storage industries are witnessing a transformative shift with the advent of 4680 cylindrical battery cells. At CNS BATTERY, we understand that evaluating new battery technology requires hands-on testing and verification. That’s why we’re offering 4680 battery cell free samples to qualified B2B partners worldwide. This initiative enables manufacturers, integrators, and R&D teams to assess performance characteristics before committing to large-scale procurement.
Why 4680 Battery Cells Matter
The 4680 designation refers to the cell’s physical dimensions: 46mm in diameter and 80mm in length. This format represents a significant evolution from traditional 18650 and 21700 cylindrical cells. The larger form factor delivers approximately five times the energy capacity while reducing overall pack complexity. From a technical standpoint, the 4680 architecture incorporates tabless design technology, which minimizes internal resistance and enhances thermal management capabilities.
For battery pack engineers, the 4680 cell offers compelling advantages in structural efficiency. The reduced cell count per pack decreases welding points, lowers assembly time, and improves manufacturing scalability. These factors directly translate to cost reduction potential of 14-16% at the pack level, according to industry benchmarks.
Technical Specifications and Performance Metrics
Our 4680 battery cells feature nickel-rich cathode chemistry (NCM 811 or NCA) paired with silicon-enhanced anodes. This combination delivers energy density ranging from 275-300 Wh/kg at the cell level. The continuous discharge rate supports 3C-5C applications, making these cells suitable for both automotive and high-power energy storage systems.
Thermal performance represents another critical differentiator. The cylindrical geometry facilitates uniform heat distribution, while the tabless current collection design reduces heat generation during high-rate charging. Operating temperature ranges span from -20°C to 60°C, with optimal performance between 15°C and 35°C. Cycle life expectations exceed 2,000 full cycles at 80% depth of discharge under standard testing conditions.
