In the context of the acceleration of domestic energy transition and the deepening of the construction of new power systems, energy storage technology innovation is constantly breaking through industry boundaries. Recently, Wuhan Huaneng Yangluo Power Plant put into operation the first domestic "supercapacitor lithium battery" composite energy storage frequency modulation project has attracted the attention of the industry, the project innovatively integrates the millisecond response characteristics of supercapacitors and the longterm energy storage advantages of lithium batteries, and realizes a breakthrough in increasing the frequency regulation response speed of the power grid by 10 times and the adjustment accuracy by 4 times, which not only sets a technical benchmark for the energysaving and carbonreduction transformation of thermal power plants, but also creates a precedent for the largescale application of hybrid energy storage in the field of power grid frequency regulation.

Sichuan Jinshi Technology Co., Ltd., an enterprise that has successfully transformed from traditional printing to the field of new energy, anchors the development track of supercapacitors and new energy storage, showing strong competitiveness, and the company and the team of Professor Yang Weiqing of Southwest Jiaotong University have built a "materialmaterialdeviceuse" whole industry chain innovation system, and its independent research and development of "coupling supercapacity and lithium battery hybrid energy storage architecture", the former is responsible for instantaneous highpower frequency regulation, and the latter ensures longterm stable power supply, fully solving the pain points of slow response and short life of traditional energy storage systems. This dual technological breakthrough has further enhanced and consolidated the leading edge of Jinshi Technology in the field of supercapacitors.

In Chengdu Longquanyi District, a national economic and technological development zone, covering an area of 111 acres, a quiet revolution is being staged. Liu Hui, marketing director of Jinshi Technology Co., Ltd., said frankly: "From printing to energy storage, it seems that the span is huge, but we are always looking for the meeting point between technology and resources. Since its establishment in 2008, Jinshi Technology has completed the transformation from traditional manufacturing to new energy and hightech fields in more than ten years. On March 23, 2025, at the 15th China International Energy Storage Conference, Jinshi Technology won the "2025 Best System Integration Award", which is not only a recognition of its technical strength, but also a sign of the success of cross-border transformation.

The history of the development of supercapacitors can be called an epic of the evolution of energy technology. From Helmholz's discovery of electric doublelayer capacitance in 1879, to the commercialization of Standard Oil in 1969, to the explosion of industrialization in the late nineties, this technology has always pushed the limits of energy and power. Compared with traditional batteries, supercapacitors have become the "speed responsibility" in the field of energy storage with millisecondlevel response speed, million cycle life, and more than 90% charge and discharge efficiency.

Coupledsuper-capacityandlithium-ionhybridenergystoragearchitecture:
Intelligent collaboration breaks through performance bottlenecks
Intheinterview,Ms.HuangJinxia,thetechnologyleaderofJinshiTechnologyCo.,Ltd.,introducedthecoretechnologyofJinshiTechnology-"coupledsupercapacityandlithiumbatteryhybridenergystoragearchitecture"to the Chinaenergystoragenetworkteamindetail. Through the self-developed core algorithm,the architecture realizes the accurate and intelligent scheduling of supercapacitors and lithium batteries,and dynamically distributes power and energy.The supercapacitor is responsible for the transient highpower primary frequency modulation,and the lithium battery ensures stable longterm energy output,and the two are perfectly coordinated to achieve the accurate matching of "transient response"and "longterm battery life". Compared with the traditional single energy storage system,this architecture greatly improves the frequency modulation efficiency and cycle life.The traditional lithium battery frequency modulation is limited by the number of cycles,which is difficult to meet the rapid response needs of the primary side of the power grid.The supercapacitor has the characteristics of second-level response and million-time long life,forming amultienergy complement with lithium battery,and significantly optimizing the frequency modulation effect.In terms of technical indicators,the internal resistance of Jinshi supercapacitors is as low as 0.18 milliohms,and the capacity consistency deviation is controlled at 5%, which is far better than that of peers,laying asolid foundation for the efficient and stable operation of energy storage systems.

Scenario-based revolution of supercapacitors: diversified applications, expanding industry boundaries

The China Energy Storage Network team learned that Jinshi New Energy broke the traditional perception that supercapacitors are only suitable for shortterm and highfrequency scenarios, and realized the comprehensive layout of supercapacitors on the source side, grid side, and user side. In addition to frequency modulation scenarios, energy compensation products are used to improve power quality for grid voltage drop on the user side, and matching products are also developed in special scenarios such as wind pitch, backup power supply, rail transit, and data centers. Using the strategy of "capacitor firstbattery followup", combined with the original "powertime" twodimensional decoupling algorithm, the application boundary of supercapacitors is extended to hourlevel scenarios, and the needs of different time scales are accurately matched, which opens up a new path for the application of energy storage technology in more fields.

Liquid nitrogen fire protection solution: safety first, guarding the lifeline of the energy storage system

The safety of energy storage is crucial, and Jinshi Technology's liquid nitrogen fire protection solution has brought subversive changes. During the interview, the technical team showed the members of the China Energy Storage Network that nitrogen accounts for 78% of the air, and itsliquid form of liquid nitrogen is used as a clean medium, which is nontoxic and harmless, and does not damage electrical components after spraying, achieving zero pollution. Its powerful fire extinguishing and cooling ability is impressive, extinguishing an open flame within 5 seconds, and reducing the minimum temperature in the pack to below -150°C within 1 minute, effectively preventing reignition. The inert gas characteristics of liquid nitrogen give it the ability to suppress explosion at the essential level, accurately extinguish the fire source, protect the devices in the protected area with zero damage, eliminate the risk of secondary disasters from the root, and provide a reliable guarantee for the safe operation of the energy storage system.

System coordination to improve the comprehensive efficiency of energy storage
In the integrated design of "sourcestoragecontrol", Jinshi Technology gives full play to the advantages of coupling architecture, and deeply integrates the power characteristics of supercapacitors, the energy density of lithium batteries and the safety solution of liquid nitrogen. Using the inherent characteristics of overcapacity and lithium battery, combined with liquid nitrogen safety dynamic balance technology, through the integrated design of "sourcestoragecontrol", with the help of AI bionic model technology and digital and intelligent collaborative distribution of power and energy, it can efficiently respond to the needs of the network end, accurately calculate and respond quickly on demand, solve the reliability and safety pain points of energy storage product applications in the industry, and significantly improve the comprehensive efficiency of energy storage systems.

As a pioneer of coupled hybrid energy storage and liquid nitrogen fire protection technology, Jinshi Technology revealed in an interview with China Energy Storage Network that the company has clear goals in terms of technology iteration and scenario expansion.

"We must not only be innovators of technology, but also be the makers of industry rules." The words of the person in charge of Jinshi Technology were loud. The experience of participating in the compilation of supercapacitor group standards for many times has given Jinshi Technology the strength to lead the industry standard. When the world is anxious about new energy consumption, energy storage security, and technology iteration, Jinshi Technology is using innovation to give the answerthis revolution that began across borders may completely rewrite the future of the energy storage industry.

According to the International Energy Agency (IEA), the global energy storage system deployment target of 1.5TW by 2030 is needed to support largescale integration of renewable energy and ensure grid stability. However, the current deployment level of energy storage systems in the world and in China is still far below this goal, indicating that the energy storage industry has huge development space and potential at home and abroad.

With the continuous innovation of technology, the gradual optimization of the policy environment, and the deepening of international cooperation, China's energy storage industry will usher in a critical period of rapid expansion in the next decade, which will not only play a central role in promoting the domestic energy transition, but also make important contributions to the sustainable development of the global energy system.
