Technological Breakthroughs and Application Prospects of YMIN SLD Series Hybrid Supercapacitors

In today's rapidly developing fields of electronics and clean energy, efficient and reliable energy storage solutions have become key drivers of technological progress. YMIN's SLD series hybrid supercapacitors are an innovative product born from this context. They successfully integrate the high power characteristics of traditional capacitors with the high energy density advantages of lithium-ion batteries, bringing revolutionary energy storage solutions to multiple industries.

Technical Characteristics:

The core advantage of the SLD series hybrid supercapacitors lies in their superior technical parameters. This series has a rated voltage of 4.2V and an ultra-wide operating temperature range (-20℃ to +70℃), enabling it to maintain stable performance in extreme environments. Compared to traditional energy storage devices, the SLD series has achieved significant breakthroughs in several aspects.

Excellent temperature adaptability is one of the notable features of the SLD series. In low-temperature environments of -20℃, the product can still be charged normally, solving the technical challenge of charging conventional lithium-ion batteries at low temperatures. Simultaneously, in high-temperature environments up to +70℃, the SLD series not only discharges normally but also maintains long-term stability. Durability testing shows that after 1000 hours of continuous operation at +70°C, the capacity change rate remains within ±30% of the initial value, and the internal resistance (ESR) increase does not exceed four times the initial standard. This characteristic makes it particularly suitable for use under harsh conditions.

An ultra-long cycle life is another major highlight of the SLD series. This product can withstand over 20,000 charge-discharge cycles, far exceeding the lifespan of traditional rechargeable batteries. This means that under normal operating conditions, the SLD series can provide stable service for several years, significantly reducing the maintenance costs throughout the device's lifecycle. This feature is especially important for applications requiring frequent charge-discharge cycles.

High energy density and rapid charge-discharge capability make the SLD series unique in the energy storage field. Its energy density is 15 times that of a double-layer capacitor of the same size, while maintaining the rapid charge-discharge characteristics of a supercapacitor. This combination allows the SLD series to provide both high energy storage and instantaneous power release and absorption, meeting the high demands of modern electronic devices on energy systems.

Practical Applications: Empowering Technological Innovation Across Multiple Fields

Based on the aforementioned technical characteristics, the SLD series hybrid supercapacitors demonstrate broad application prospects in multiple fields.

In the e-cigarette and portable digital product sectors, the SLD series' small size and high energy density make it an ideal power source. Taking the SLD4R2L7060825 model as an example, its diameter is only 8mm and its length is 25mm, yet it provides a capacity of 30mAh and a maximum internal resistance of 500mΩ. This compact design helps device manufacturers achieve longer battery life within limited space, while user waiting time is significantly reduced thanks to its fast charging capabilities.

In the electric vehicle industry, the SLD series can be used for auxiliary power systems, regenerative energy recovery, and instantaneous power compensation. Especially in start-stop systems, the SLD series can efficiently absorb and release braking energy, improving overall vehicle energy efficiency. Its wide temperature adaptability ensures normal operation in both the high-temperature environment of the engine compartment and the low-temperature environment of cold regions, enhancing the reliability of electric vehicles.

In renewable energy storage, the SLD series' fast response characteristics make it ideal for smoothing fluctuations in solar and wind power generation. Compared to traditional batteries, the SLD series can handle frequent charge-discharge cycles more effectively, extending system lifespan. Simultaneously, its high-temperature stability reduces the need for cooling systems, lowering the operation and maintenance costs of energy storage systems.

In industrial energy management, the SLD series can be used for peak power compensation, power outage protection, and voltage stabilization. For example, in automated production lines, the SLD series can provide instantaneous energy for equipment experiencing sudden high power surges, preventing impact on the main power grid. Its long lifespan significantly reduces maintenance frequency and costs for industrial users.

Technical Advantages: Comparison with Traditional Energy Storage Devices

Compared to traditional electric double-layer capacitors and lithium-ion batteries, the SLD series hybrid supercapacitors exhibit significant advantages in multiple dimensions.

Compared to electric double-layer capacitors, the SLD series has several times higher energy density, meaning more energy can be stored in the same volume. At the same time, the SLD series' operating voltage (4.2V) is much higher than traditional supercapacitors (typically 2.5-2.7V), reducing the number of series connections and improving system reliability.

Compared to lithium-ion batteries, the SLD series boasts faster charge/discharge rates, longer cycle life, and improved safety. Its power density is significantly higher than lithium-ion batteries, enabling it to withstand higher-intensity pulse currents. In terms of safety, the SLD series utilizes a more stable material system, avoiding the thermal runaway risks inherent in traditional lithium-ion batteries.

Comprehensive Specifications: Meeting Diverse Needs

The YMIN SLD series offers a variety of capacities from 70F to 1300F, with sizes ranging from 8mm to 18mm in diameter, catering to the space constraints and performance requirements of various applications. For example, the compact SLD4R2L1071020 (10mm diameter, 20mm length) is suitable for space-constrained portable devices, while the larger capacity SLD4R2L1381840 (18mm diameter, 40mm length) is ideal for industrial applications requiring higher energy reserves.

Each model undergoes rigorous testing to ensure compliance with RoHS and REACH environmental standards, reflecting YMIN's commitment to environmental protection and sustainable development.

With the rapid development of the Internet of Things (IoT), electric vehicles, and renewable energy, the demand for high-efficiency energy storage solutions will continue to grow. YMIN's SLD series hybrid supercapacitors, with their unique technological advantages, are expected to play a greater role in the following areas:

In smart home and IoT devices, the SLD series' long lifespan and maintenance-free characteristics are particularly suitable for distributed sensor networks, significantly reducing maintenance costs.

In medical electronic equipment, where the reliability and safety requirements of power supplies are extremely high, the SLD series' high safety and wide temperature adaptability make it an ideal choice.

In the aerospace and defense sectors, there are special requirements for the extreme environmental adaptability and reliability of energy storage devices, and the technical characteristics of the SLD series are highly compatible with these needs.
