Say Goodbye to Low-Temperature Range Anxiety: YMIN SLR Series Hybrid Supercapacitors Solve the All-Climate Energy Storage Challenge

I. Energy Storage Technology Challenges and Industry Needs in Extremely Cold Environments

In high-latitude regions such as North America and Northern Europe, winter temperatures are generally below -20°C, and can reach -40°C in extreme conditions. Traditional battery-powered solutions have significant technical shortcomings in low-temperature scenarios: substantial capacity degradation and a sharp increase in internal resistance, making it difficult to ensure continuous and stable operation of outdoor equipment.

With the global large-scale deployment of the Internet of Things and smart meters, the upgrade of energy storage devices from “room-temperature applicable” to “all-climate resistant” has become an inevitable trend. At the same time, the new EU battery regulations (EU 2023/1542) impose stringent requirements on carbon footprint, recycled materials, and compliance certification. Coupled with the high transportation and storage costs and complex processes due to the hazardous nature of batteries, this is driving the industry to seek safer, more compliant, and lower-cost alternative energy storage solutions.

II. YMIN SLR Series Hybrid Supercapacitor Technology Solution

YMIN Electronics, relying on material system innovation and structural optimization design, has launched the SLR series hybrid supercapacitors. With stable operation at ultra-low temperatures down to -40℃, these capacitors provide all-weather energy storage for outdoor equipment such as IoT terminals, smart meters, automotive electronics, container positioners, and tower base station monitoring.

1. Ultra-wide operating temperature range, covering extremely cold application scenarios

The SLR series achieves stable operation across a full temperature range of -40℃ to +85℃. It can directly cold-start at -40℃ without additional heating auxiliary devices, fundamentally solving the industry problem of battery electrolyte freezing and inoperability at low temperatures. It is suitable for long-term outdoor deployment in high-latitude, extremely cold regions.

2. Low-Temperature Capacity and Internal Resistance Stability Design

Addressing the pain points of low-temperature capacity decay and sudden increase in internal resistance, YMIN achieves excellent low-temperature performance through electrolyte formulation and electrode structure optimization:

 Capacity Stability: Capacity deviation at 25℃: -10% to +30%; Capacity decay <30% at -40℃, ensuring sufficient energy storage for low-temperature start-up.

 Internal Resistance Controllability: In high and low temperature cycling tests, internal resistance change <4 times the initial value, indicating stable material structure and preventing uncontrolled increase in internal resistance.

3. EU Regulatory Compliance Advantages

The SLR series belongs to the capacitor category and is not subject to the new EU battery regulations. It eliminates the need for complex certification processes such as carbon footprint declarations and due diligence, significantly reducing export compliance costs and timelines.

4. Ultra-Long Lifespan and Low Maintenance Costs

Utilizing physical energy storage principles, the charge-discharge cycle life is ≥250,000 cycles, matching the 10-year design life of equipment, significantly reducing the total lifespan replacement and maintenance costs.
