Introduction In the rapidly evolving landscape of renewable energy, the role of energy storage devices in power systems is becoming increasingly prominent. As the core component of energy storage devices, the performance and quality of battery cells directly determine the efficiency and reliability of the entire energy storage system. Among various types of battery cells, Lithium Iron Phosphate (LiFePO4) energy storage cells are widely applied in energy storage devices due to their unique advantages. This article will unveil the answer to why LiFePO4 is considered the most reliable energy storage core from a technical perspective.

Advantages of 9xe Lithium Iron Phosphate Energy Storage Cells

High Safety:

• Our cells have passed safety standard tests such as UL9540A and IEC62619.

• In puncture tests, the cells exhibit no open flame, no smoke, with a temperature peak of only 120°C.

• After continuous burning at 600°C for 2 hours, the cell structure remains intact.

Rapid Response and High Rate Charge/Discharge Capability:

• Cells can be charged to 80% capacity within 30 minutes.

• Under a high-rate discharge condition of 10C, cells can still maintain 90% capacity output.

High Charge/Discharge Conversion Efficiency: Our cells achieve an actual charge/discharge conversion efficiency of 95.5%.

Strong Environmental Adaptability:

• Even at -20°C, cells can release 85% of their rated capacity

• In a high-temperature environment of 50°C, the capacity decay rate is only 5% per year.

Detectability and Diagnosability: Real-time monitoring of cell health status is provided, enabling the early detection of potential faults.

Cost Advantage: Compared to other high-end cells, our cells have reduced costs by 25%, with no compromise on performance and quality.

How 9xe Lowers Costs by Increasing Production Capacity

In the Chinese market, 9xe has consistently supplied stable battery cells for large-scale energy storage projects. By continuously increasing production capacity, we have successfully achieved cost optimization. Specifically, in the past year, we increased production capacity by 30%, resulting in a 15% reduction in the production cost per cell. This strategy not only allows us to meet the growing market demand but also provides users with more economical and reliable energy storage solutions.

To better illustrate the advantages and application value of 9xe LiFePO4 energy storage cells, we present some practical data and case studies:

• In a national grid energy storage demonstration project using our 1MWh cell system, the overall efficiency reached 92% after one year of operation, far exceeding the expected target.

• We installed a 5MWh cell system in a photovoltaic power station in Qinghai. Even in the harsh conditions of high-altitude strong winds and dust, the system operated stably with efficiency maintained above 90%.

• Deploying a 10MWh cell system for peak-shaving in a large industrial park in Guangdong, the system saved over 30% of electricity costs for the enterprise within six months.

• Collaborating with a top domestic electric vehicle manufacturer, providing cell matching for over 50,000 electric vehicles, our cells have experienced zero safety incidents, earning consistent praise from users.
