Breaking Performance Boundaries: YMIN Hybrid Supercapacitor (SLA Series) Redefines Energy Storage Solutions

In today's rapidly evolving electronics industry, the performance of energy storage components directly determines the reliability and efficiency of the entire system. Yongming's Hybrid Supercapacitor (SLA series), an innovative fusion of traditional capacitors and lithium-ion batteries, is bringing revolutionary breakthroughs to the energy storage field with its superior overall performance.

Technical Principle: A Design Philosophy of Fusion and Innovation

The Hybrid Supercapacitor cleverly combines the high power density of double-layer capacitors with the high energy density of batteries. Its core working principle lies in using activated carbon materials similar to those in supercapacitors at the positive electrode to achieve a rapid physical adsorption/desorption process; while using carbon materials capable of embedding lithium ions at the negative electrode to store energy through electrochemical reactions. This hybrid structure allows the SLA series to significantly improve energy storage density while maintaining the rapid charge and discharge characteristics of supercapacitors, resolving the technical contradiction of traditional energy storage components that struggle to simultaneously achieve "high energy" and "high power."

Superior Performance: Redefining Industry Standards

The SLA series Hybrid Supercapacitor boasts several remarkable technical features that set it apart from its competitors:

Wide Temperature Range Operation: The product can be charged normally at -20°C and discharged stably at temperatures up to +85°C, covering an operating temperature range of -40°C to +85°C, ensuring stable performance in various extreme environments. This feature makes it particularly suitable for applications such as outdoor electronic devices and automotive electronics.

Ultra-High Power Density: Supporting 20C continuous charging, 30C continuous discharging, and 50C instantaneous discharging capabilities, this means that even high-capacity products like the 1500F can provide massive pulse currents for short periods, meeting the instantaneous high-power demands of devices.

Extra-Long Cycle Life: Tested at 25°C, after 250,000 charge-discharge cycles within the 3.8V-2.5V range, the SLA series exhibits a capacity change of less than 30% of its initial value, and an internal resistance increase of no more than four times. This lifespan far exceeds that of traditional rechargeable batteries, significantly reducing maintenance costs throughout the entire device's lifecycle.

Exceptional Reliability: After being subjected to rated voltage for 1000 hours at 85°C, product performance degradation remains within acceptable limits. Furthermore, it maintains stable electrical characteristics even after 240 hours of continuous operation in a high-temperature, high-humidity environment of 40°C and 90-95%RH.

Ultra-Low Self-Discharge Rate: The product's self-discharge rate is as low as ≤1.5mV per day on average, meaning it can effectively maintain energy storage and reduce energy waste during long standby applications.

Practical Applications: Multi-Domain Solutions

Internet of Things (IoT) Devices

For widely distributed IoT sensor nodes, the SLA series' wide temperature range and long cycle life make it an ideal power solution. Whether it's environmental monitoring equipment in remote areas or smart manhole cover sensors in cities, SLA products ensure long-term stable operation, significantly reducing maintenance frequency and costs.

Smart Metering Systems

In smart metering devices such as water meters, gas meters, and heat meters, the SLA series can be used in conjunction with a primary lithium battery as a peak power compensation power source. When equipment requires data communication or valve operation, SLA provides instantaneous high current, protecting the main battery from high-current surges and extending the overall system lifespan.

Automotive Electronics

In automotive electronic devices such as ETC on-board units and dashcams, the high and low temperature performance of SLA products ensures reliability under extreme climatic conditions. Its fast charge and discharge characteristics meet the instantaneous high current demands of equipment, such as the rapid communication of ETC devices and the emergency recording and saving of dashcam footage.

Industrial Automation Equipment

For equipment such as AGVs (Automated Guided Vehicles) and industrial robots, the high power density of the SLA series supports frequent start-stop operations and instantaneous high-power output, improving equipment response speed and production efficiency. Long cycle life reduces maintenance costs in industrial environments.

Communication Auxiliary Power Supply

In applications such as 5G communication base stations and GPS tracking equipment, SLA products can serve as backup power supplies, providing continuous power support when the main power supply fails. Its fast charging characteristics ensure rapid replenishment of power after power restoration, preparing for the next emergency use.

Technical Advantages: Comparison with Traditional Components

Compared to traditional double-layer capacitors, the SLA series offers up to 10 times the capacity in the same volume, significantly improving energy density. Compared to lithium-ion batteries, SLA offers faster charge/discharge speeds, longer cycle life, and higher safety. This balanced performance makes it a "third type" energy storage solution, positioned between traditional capacitors and batteries.

Especially in terms of safety, the SLA series is manufactured using safe materials, posing no risk of explosion or combustion, and complies with RoHS and REACH directives, meeting the high environmental and safety standards of modern electronic products.

With the rapid development of technologies such as the Internet of Things, new energy, and artificial intelligence, the demand for efficient and reliable energy storage components is increasing. The SLA series Hybrid Supercapacitor, with its comprehensive performance advantages, has broad application prospects in smart homes, new energy vehicles, renewable energy storage, wearable devices, and other fields. Especially in the global context of pursuing "carbon neutrality," the value of efficient energy utilization components will be further highlighted.
