The renewable energy revolution is reshaping global energy dynamics, with lithium-ion batteries at its core. Among their critical components, separators play a vital role in ensuring battery stability and safety. These small yet sophisticated barriers isolate positive and negative electrodes while allowing lithium ions to flow freely during charge and discharge cycles—a responsibility essential to battery performance and reliability.

At Liaoyuan Hongtu, a leading lithium battery separator manufacturer in northeast China, production operates 24/7 with high precision and intensity. Polymer solutions are meticulously coated using advanced equipment, then processed under tightly controlled conditions to form micropores and stabilize structures before being rolled, cut, inspected, and packaged. This intricate production process requires consistent power and stringent environmental controls, creating immense energy demands.

As a domestic pioneer in lithium battery separator production, Liaoyuan Hongtu has mastered the R&D and manufacturing of high-end wet-process separators. They are also committed to sustainable production methods. Through the adoption of Sigenergy’s energy solutions, the company has transitioned to renewable energy-driven manufacturing. Equipped with Sigenergy's commercial and industrial (C&I) inverters and a 5MW solar PV system, the factory saves approximately 6 million kWh of electricity annually, reducing carbon emissions by 4,200 tons—the equivalent of planting 233,000 trees each year. This achievement sets a new standard for sustainability in the lithium separator industry.

Advanced AFCI Technology: Ensuring Safety and Stability

The production of lithium battery separators demands not only substantial energy but also a stable power supply and robust safety measures. Any fluctuation or disruption could compromise product performance and efficiency. To address these challenges, Sigenergy’s C&I inverters incorporate advanced Arc Fault Circuit Interruption (AFCI) technology, a crucial safety feature for high-precision industries.

Sigenergy’s inverters offer an industry-leading 500-meter long-range AFCI capability, achieved through advanced hardware, multi-layered algorithms, and AI optimization. This extended protection range ensures system safety in even the most complex setups, eliminating concerns of AFCI failure during system design and allowing for greater operational flexibility.

Ultra-Fast Communication and Energy Management

Sigenergy revolutionizes energy management with its full-network communication technology, which outperforms traditional RS485 protocols. With speeds improved by several magnitudes, Sigenergy enables over 10x faster system upgrades and delivers industry-best anti-backflow responses in under 0.5 seconds, effectively preventing grid overload and voltage fluctuations.

The system’s integrated energy management system (EMS) eliminates the need for external data loggers, significantly reducing commissioning time. The streamlined design simplifies maintenance, while ultra-fast communication enhances the precision and efficiency of energy management.

Real-Time Cloud-Native Monitoring

Sigenergy’s cloud-native architecture provides real-time dynamic data refresh in as little as 10 seconds—an improvement of tens of times over traditional solutions. This rapid data processing enhances operational efficiency and offers immediate safety protections. In industrial energy systems, swift responses to equipment failures, current fluctuations, or temperature anomalies reduce risks and ensure smooth operations.

Flexible Scalability for Future Growth

With reserved storage interfaces, battery modules can be seamlessly integrated without the need for major equipment overhauls, reducing upgrade costs while maximizing long-term flexibility. The modular design of Sigenergy's solar storage systems delivers exceptional scalability, enabling enterprises to begin with a smaller setup and expand storage capacity as their business needs evolve.
