New Application Breakthrough! Xibei Power's High-Power Sodium-Ion Battery System Successfully Delivered to Oilfield Project
Recently, the self-developed sodium-ion battery system by Xibei Power completed the successful shipment of its first sample, which will be delivered to a domestic oilfield well site for operation. This project milestone marks the breakthrough of Xibei Power's high-power sodium-ion batteries in the oilfield industrial energy storage scenario, providing a new generation of energy storage solutions with high safety, low-temperature resistance, and high power for the green and low-carbon transformation of the oil and gas industry.
**Precise Matching of Scenario Pain Points, Core Sodium Battery Performance Adapted to Harsh Oilfield Conditions**
Major oil and gas fields in northern and northwestern China have long faced five key energy challenges: severe cold and low temperatures, high-power impact loads from pumping units, open-air unattended operation, off-grid emergency power supply, and high costs. The drawbacks of existing lithium batteries and diesel generator solutions in oilfields are evident: lithium batteries suffer from a sharp capacity drop at low temperatures, a significantly reduced lifespan under high-current impact, high maintenance costs for diesel generator sets, and excessive carbon emissions. The energy storage system delivered this time is equipped with Xibei Power's high-power battery system, leveraging its high-power characteristics to support a charge/discharge power of 1MW, perfectly matching the operating conditions of oilfield equipment. Compared to the original solution, the battery capacity is significantly reduced, offering outstanding cost advantages and full adaptability to the extreme working environments of oilfields.
**The sodium battery system applied in oilfields features the following prominent advantages:**
1. **Ultra-wide temperature range operation:** The cell exhibits excellent low-temperature performance, with a capacity retention rate above 90% at -20°C and the ability to cold-start discharge at -40°C without preheating equipment, meeting the year-round continuous operation needs of northern extreme cold well sites and completely solving the winter power shortage issue.
2. **High-rate impact resistance:** It supports instantaneous high-power loads from pumping units, enabling stable and efficient charge/discharge within a 10% to 95% state of charge range.
3. **Intrinsic safety and reliability:** The cell adopts a polyanion system, ensuring intrinsic safety and reliability; the battery system is equipped with an intelligent BMS, efficient thermal management, and multi-layer insulation design, achieving an NTP (no thermal propagation, no combustion) effect, fully meeting the unattended operation and maintenance requirements of remote well sites.
**Multi-Scenario Deployment**
The delivery of the oilfield energy storage project represents an important application breakthrough for Xibei Power in the traditional industrial energy sector, following its successes in engineering machinery, commercial vehicles, passenger vehicles, and ultra-fast charging energy storage. Leveraging its mature high-power sodium-ion battery products, the company's offerings now cover various power and energy storage scenarios. Xibei Power will continue to intensify R&D efforts, collaborate with industry chain partners, launch customized sodium battery solutions, expand the application fields of sodium-ion batteries, assist high-energy-consuming industries in green electrification transformation, and build a new low-carbon economic ecosystem.
