33140AL Cylindrical Cell

The AuroraCell 33140AL Sodium-Ion Cylindrical Cell delivers a carefully engineered balance between high energy capacity and strong power output, making it one of the most versatile solutions in the growing sodium-ion battery market. With a capacity of 8300 mAh (24.07 Wh), this advanced cylindrical sodium-ion battery cell enables more efficient system design by reducing the total number of cells required. Fewer cells mean fewer interconnections, simplified battery management systems (BMS), and faster assembly—key advantages for engineers and manufacturers looking to optimize both performance and production efficiency.

At the core of the 33140AL is AuroraCell’s advanced NaCrO₂ (Sodium Chromium Oxide) chemistry, which delivers a combination of high efficiency, enhanced safety, and long operational life. With a round-trip efficiency exceeding 96%, the cell minimizes energy losses during charge and discharge cycles. This results in lower heat generation, reduced thermal stress, and improved overall system durability. For applications where efficiency directly impacts performance and cost, this high-efficiency sodium-ion battery offers a significant advantage over traditional alternatives.

Safety is another key differentiator. Sodium-ion chemistry is inherently more stable than many lithium-based systems, and the 33140AL is specifically designed to reduce the risk of thermal runaway. This makes it an attractive choice for applications requiring robust safety standards, including industrial equipment, mobility systems, and portable energy storage. For companies seeking a safer alternative to lithium-ion batteries, this cell provides a reliable and future-ready solution.

One of the standout features of the 33140AL is its exceptional performance in extreme environments. The cell retains over 90% of its capacity at -40°C, ensuring consistent operation in cold climates where conventional batteries struggle. This makes it ideal for outdoor applications, winterized equipment, and cold-chain operations, eliminating the need for additional heating systems and reducing overall energy consumption.

From a logistics and operational standpoint, the ability to fully discharge the cell to 0V (zero-voltage shipping) provides a major advantage. This enables safer transportation, simplifies compliance with international battery shipping regulations, and allows for long-term storage without damaging the cell. For manufacturers and distributors managing large inventories, this improves safety while increasing flexibility in supply chain operations.

The cylindrical format of the 33140AL ensures compatibility with standard battery manufacturing processes, including both spot welding and laser welding. This allows seamless integration into existing production lines without the need for specialized equipment or major process changes. As a result, companies can accelerate development cycles and reduce time to market when adopting sodium-ion battery technology in Europe.

Fully certified with CE and UN38.3 standards, and supported by local EU stock availability, the AuroraCell 33140AL guarantees reliable supply and fast delivery across Europe within five working days. This ensures that projects remain on schedule without the delays often associated with overseas sourcing.

The 33140AL is ideally suited for a wide range of applications, including light electric mobility (e-bikes, scooters, utility vehicles), portable power stations, industrial tools, and modular battery pack systems. For engineers searching for a high-capacity cylindrical sodium-ion battery with strong power performance, the AuroraCell 33140AL offers an optimal combination of efficiency, safety, and design flexibility.
