Molicel's S Series: Setting New Standards for Safety in Battery Backup Systems and AI Computing

Molicel's S Series: A Leap Forward in Battery Safety and Performance

Molicel, a pioneer in advanced battery technology, has unveiled its groundbreaking S Series at the International Battery Seminar 2025. Slated for release in 2025, this new line of ultra-high-performance cells is tailored specifically for battery backup units (BBUs), hyperscale data centers, and AI computing environments.

The S Series offers unparalleled performance, available in two primary cell formats: 18650 and 21700. The 18650 format features the INR-18650-P22S, providing a maximum output of 100W and a discharge current of 36A, while the INR-18650-P30S reaches up to 160W with 54A. On the larger 21700 format, the INR-21700-P50S can deliver an impressive 200W with a discharge current of 100A, ensuring that demanding applications have the reliable power they require.

The S Series is engineered with a focus on safety, low flammability, and high discharge capacity, making it an excellent choice for critical applications where reliability is key. With backup times exceeding 1.5 minutes and a long shelf life of up to 6 years, Molicel demonstrates its commitment to excellence in the battery sector.

A distinctive feature of the S Series is its advanced interface technology, resulting from meticulous design and the innovative SEI/CEI technologies. These enhancements translate into extremely low internal impedance of just 13 mΩ and exceptional reliability throughout their lifespan, even under elevated temperatures ranging from 35 to 45 degrees Celsius.

As the demand for computing power grows—particularly with the use of NVIDIA's GB300 processors that require enhanced energy management solutions—the reliance on BBUs is expected to rise. Molicel's design meets the stringent OCP ORV3 standards for power consistency across high-performance servers.

In pursuit of optimal safety, Molicel is actively researching and developing high-security cell designs to mitigate flammability risks. The company is prioritizing thermal behavior management in its battery cells, utilizing advanced thermal stable separators to manipulate gas release behaviors successfully. This approach is designed to enhance the overall safety of battery packs in data centers, especially in environments requiring high performance and security.

Casey Shiue, President of Molicel, emphasizes the importance of safety in the S Series, stating, "Our ultra-high-performance cells are designed not only to offer superior reliability and performance but also to maintain the highest levels of safety for critical applications, such as BBUs and data centers. Our commitment to innovation is evident in our ongoing supply to major cloud service providers."

Molicel's legacy dates back to its establishment in 1998, and it remains a leading manufacturer of high-quality rechargeable lithium-ion cells and battery packs. Grounded in over 40 years of experience in the rechargeable battery sector, Molicel is renowned for its performance-optimized cylindrical cells, achieving remarkable energy density for both high discharge and rapid charging capabilities.

This commitment to continuous research and development is aimed at enhancing battery performance, safety, and sustainability. With the S Series, Molicel seeks to deliver cutting-edge ultra-high-performance cells that align with the rapidly evolving demands of AI and data center applications, solidifying its position as a trusted leader in the field.

In conclusion, Molicel's S Series represents a significant advancement in the battery technology landscape, promoting safer, more efficient energy solutions for the future. As data centers continue to grow in complexity and power requirements, Molicel remains dedicated to leading the charge with innovative products that prioritize safety without sacrificing performance.
