Green Tech Holds 2026 High-End Capacitor Industry Trend Seminar
Recently, Greentech convened its 2026 Annual High-End Capacitor Industry Trend Seminar, conducting in-depth analysis of market dynamics, technological directions, and growth opportunities across four core product categories: supercapacitors, tantalum capacitors, mica capacitors, and lithium-ion capacitors.
Q&A on Supercapacitors
Supercapacitors are next-generation energy storage devices that function similarly to batteries, capable of charging and discharging. The key difference in their energy storage principle lies in the fact that supercapacitors—specifically those of the electric double-layer type—rely solely on physical adsorption rather than chemical reactions. With a market share comparable to traditional batteries, supercapacitors are poised to become one of the critical pillars supporting the future development of advanced mobile technologies.
Precautions for Using GTCAP Supercapacitors
Unlike conventional electrolytic capacitors or batteries, supercapacitors theoretically have no polarity because their positive and negative electrodes are made of the same material. However, the polarity markings on supercapacitors are determined by manufacturers during the production process. If the capacitor is accidentally used in reverse for a short period during operation, it will not cause substantial damage to the device; simply reversing it back to the correct orientation will restore normal functionality. Nevertheless, prolonged reverse usage can lead to rapid degradation of the capacitor's performance and significantly shorten its lifespan.
GTCAP Supercapacitor Testing Methods
Main Parameter Testing Methods for GTCAP Supercapacitors
GTCAP successfully enter the Russian military industry market.
As a veteran provider of military-grade capacitors, GTCAP has already earned a strong reputation both domestically and internationally. In recent years, driven by the nation's increasing demands for advanced military equipment and bolstered by substantial investments in research and development, the company's products have not only matched but even surpassed those of internationally renowned brands.
The demonstration section of the Huangpu Supercapacitor Energy Storage Tram Line 1 has been opened ahead of schedule, enabling the recovery of more than 80% of braking energy.
On the morning of July 1, the demonstration section of Huangpu District's Tram Line 1 officially opened for trial operations, accompanied by the launch ceremony of the "Huangpu in Full Bloom" themed train at Lingfu Vehicle Depot. According to Li Xionghui, General Manager of Guangzhou Development Zone Investment & Transportation Group, the demonstration section effectively connects multiple community hubs, including Changping Village, Shantang Village, Qiangdong Village, Changlingju Primary School, and the Southern Chinese-English Bilingual School, significantly benefiting over 100,000 residents along Yongshun Avenue with improved transportation access.
GTCAP achieved remarkable success at the 2016 Electronica trade show in Munich, Germany.
GTCAP made its debut at the 2016 Munich Exhibition, achieving remarkable success. Our company placed great importance on this exhibition and meticulously prepared beforehand, delivering a high-quality showcase tailored specifically for both the European market and global audiences. During the event, we exhibited our supercapacitors, tantalum capacitors, and mica capacitors—products renowned for their exceptional cost-performance ratios—and presented customers with a wide range of cutting-edge application solutions for supercapacitors. These offerings not only captured the attention of numerous visitors but also sparked significant interest, enabling us to provide practical technical support that addressed real-world challenges in supercapacitor applications for many clients.
Advantages of High-Energy Hybrid Tantalum Capacitors in UAV Applications
The GTCAP series of high-energy hybrid tantalum capacitors from GTCAP—including models THC1, TCH1W, THC2, TCH2W, THC3, THC3W, THC5, THC5W, THC6, and THC6W—are all sealed using a laser seamless welding process. Additionally, these products feature high-strength glass insulators combined with multiple rigorous procedures, including vacuum testing and underwater testing, ensuring exceptional sealing performance. This guarantees that the capacitors remain leak-free even in high-altitude environments with thin air, effectively preventing any risk of liquid leakage or altitude sickness. As a result, they are perfectly suited to meet the demanding high-altitude operational requirements of various advanced drones.
Smart Water Meter Based on Supercapacitors
Intelligent water meters typically rely on built-in lithium batteries to control the opening and closing of water valves. Lithium batteries offer several advantages, including lightweight design, high energy density, and low self-discharge rates. However, since these smart water meters are not equipped with rechargeable circuits, the lithium batteries eventually lose their ability to supply sufficient power to the control circuitry after a certain period of use. As a result, the batteries must be replaced.
More than 20 types of domestically produced military drones, including the Yilong-X, make their debut at the airshow, showcasing an increasingly sophisticated and comprehensive drone collaboration system.
On November 12, the 15th China International Aviation & Aerospace Exhibition opened at the Zhuhai International Airshow Center. The China Aviation Industry Corporation showcased over 20 advanced unmanned aerial vehicles (UAVs) from its independently developed "Wing Loong" and "Cloud Shadow" series. Among them, more than 10 UAV models—including the Wing Loong-6 and Cloud Shadow-350—made their debut to the public. Additionally, the integrated anti-submarine configuration of the Wing Loong-X UAV was unveiled for the first time.
The Impact of Pingjiang County's Mica Industrial Cluster on the Production of GTCAP High-Voltage, High-Temperature Mica Capacitors
According to media reports: Pingjiang County has launched a cloud mica industry cluster worth over 10 billion yuan this year, integrating comprehensive mica industries ranging from materials to finished products. This development provides GTCAP with an additional raw material procurement option for its mica capacitors, further strengthening the production capacity and delivery timelines of GTCAP mica capacitor products.
[Research Progress] Advances in Carbon Fiber Applications for Flexible Supercapacitors
With the rapid development of portable and wearable smart electronic devices, the demand for energy storage devices has been steadily increasing. Traditional supercapacitors, however, have struggled to meet these evolving requirements. Flexible supercapacitors, with their lightweight, bendable design, and excellent cycling stability, have emerged as a new generation of energy storage devices holding immense potential. This article reviews recent research progress on carbon fiber-based flexible supercapacitors, summarizes the existing challenges in this field, and provides future perspectives.
