Diversified technological routes are becoming an important direction for the development of the energy storage industry. In this technological transformation, TianNeng has been continuously laying out multiple chemical systems such as lead, lithium, hydrogen, and sodium, and extending its core battery cells to PACK, battery clusters, and energy storage systems. Among them, the sodium-ion battery cells for fixed energy storage, due to their advantages in low-temperature performance and safety, have become an important technological route in TianNeng's energy storage product system.

Sodium-ion batteries are rapidly emerging as an important supplement and potential alternative to lithium batteries, boasting inherent high safety, abundant raw material reserves, and a more resilient supply chain. Tianren sodium battery cells, while adhering to the mainstream size specifications of the energy storage industry, combine the chemical advantages of polyanionic cathodes with large-capacity engineering capabilities. While maintaining long lifespan and safety, they further expand the application scenarios such as low temperatures, high altitudes, and off-grid environments, which are challenging for traditional lithium batteries.

Based on the polyanion route specifically optimized for fixed energy storage, the Tianren sodium battery cell maintains a capacity retention rate of ≥ 80% at -30℃. Meanwhile, the product has passed the strict abuse tests such as puncture and overcharge as stipulated in GB/T 44265-2024. It aims to prevent fire and explosion, providing a safe foundation for household, industrial and commercial, and grid-level energy storage. For users in cold northern regions, high-altitude areas or off-grid scenarios, it is not merely a substitute for lithium batteries, but a more adaptable technical choice for specific application scenarios.

Tianneng's sodium battery strategy goes beyond the core battery cells. Leveraging its independently developed sodium-ion battery cells, Tianneng further develops energy storage products covering various application scenarios such as household energy storage and grid-level energy storage, achieving a product extension from "core battery cells" to "system solutions".

In the field of grid-level energy storage, Tianneng has laid out high-performance sodium battery energy storage technology and launched high-voltage large-capacity sodium battery energy storage battery clusters. The products adopt a 1500V high-voltage platform and a 1.5MWh large-capacity design, featuring ultra-long cycle life, high power output, and wide temperature range adaptability. The cycle life can reach 15,000 times, and they can adapt to a wide temperature range of -30℃ to 60℃, and support multi-level collaboration of BMS, EMS, and power station monitoring platforms, providing long-life, high-reliability, and highly adaptable energy storage solutions for large-scale energy storage power stations.

Safety is not just a promise; it is a complex system of protective measures. Tianneng’s  energy storage system, built around sodium battery cells, constructs a comprehensive safety barrier through seven key aspects: material safety, cell safety, BMS safety, PACK safety, charger safety, certification safety, and health diagnosis. The inherent safety of the sodium electrochemical system, combined with intelligent battery management and full life-cycle health monitoring, ensures controllable and traceable safety.

Tianneng doesn't merely install battery cells in cabinets; it conducts the entire process of engineering independently, from raw material selection, battery cell chemistry system, battery pack architecture, thermal management to end-of-life recycling. Taking the 192V / 100Ah household energy storage unit as an example, the high safety and low-temperature resistance characteristics of sodium battery cells are fully inherited, forming a modular and remotely manageable household energy storage product.

When you choose the Tianneng energy storage system, what you invest is far more than just a single hardware device. Tianneng not only regards itself as a supplier of energy storage systems but also a long-term partner in this energy transformation. In the future, Tianneng will form a diversified industrial ecosystem of lead, lithium, hydrogen, and sodium, using each technology route in the most suitable place, and achieving a cleaner energy future through uncompromising product delivery and responsible construction methods.
