In the era of energy storage, electrochemical energy storage is in a critical period of transformation from the initial stage of commercialization to large-scale development, and electrochemical energy storage has the advantages of small geographical location, short construction period, and continuous cost reduction, and is currently the fastest developing energy storage technology in the industry.
In the future, driven by government support policies, further reduction in the cost of energy storage systems, and increased awareness of energy storage, the global installed capacity of new electrochemical energy storage is expected to increase from 69.0GWh in 2022 to 652.4GWh in 2027. In the fierce competition, how can electrochemical energy storage companies stand out from the encirclement?

Multi-party collaboration to break through the dilemma
On April 10, the ESIE2024 summit forum of the "12th Energy Storage International Summit and Exhibition" opened in Beijing, and Li Weijun, vice president and general manager of Sunwoda Energy Storage Product Line, was invited to attend and bring a keynote speech on "Exploration of the Core Competitiveness of Electrochemical Energy Storage under the Background of "Double Carbon", providing new ideas for enterprises to build the core competitiveness of electrochemical energy storage.
The current electrochemical energy storage battery technology has entered a new product revolution cycle. Electrochemical energy storage batteries will develop in the direction of high power and large capacity to meet the applications of different scenarios. Li Weijun said that although the electrochemical energy storage industry is entering a stage of large-scale development, from the perspective of long-term sustainable and healthy development, it is still necessary to pay attention to issues such as safety improvement and diversified technology development.
Safety risks are an unavoidable problem for new energy storage, especially electrochemical energy storage. In recent years, electrochemical energy storage safety accidents are common, and local governments have frequently issued relevant policies to implement supervision and normative standards.
In terms of technology, thanks to the continuous innovation of material system and cell structure design, energy storage cells are iterating in the direction of higher energy density and longer cycle life, and governments at all levels are supporting the diversified development of various technical routes by continuously promoting the construction of demonstration pilot projects.
Under the broad market space, with the continuous improvement of relevant supporting policies, the new energy storage industry, especially the electrochemical energy storage industry, will usher in explosive growth. At the same time, the government should improve policies to break the dilemma of the technical model and work together to get out of the pain of the industry.
Standing at the head of the tide
Four Capabilities "Go Hand in Hand"
Li Weijun, vice president of Shenzhen Sunwoda Energy Technology Co., Ltd., pointed out in the theme report "Exploration of the Core Competitiveness of Electrochemical Energy Storage in the Context of "Double Carbon" that the standardization of energy storage has entered the "ongoing", with more perfect technical standards, more stringent testing and certification standards, more comprehensive application fields and coverage, and continuous improvement of service requirements.
In order to cope with changes, Sunwoda adheres to the spirit of long-termism and values of thinking. The first is the full-stack self-research capability, Sunwoda can do the R&D and production from the battery cell to the DC cabin to the whole system; the second is the continuous innovation ability, Sunwoda has been doing electrochemical energy storage system since 2013, and so far the whole system and battery cell iteration has been more than three generations; the third is the comprehensive service ability, Sunwoda not only provides simple battery cells or energy storage systems, but also has the ability to design and build energy complexes; and the fourth is the ability to resist the industry cycle.
Sunwoda has focused on new energy for nearly 30 years, adhered to the two core elements of technological innovation and quality and safety, adhered to the "long-termism", and has developed into an "all-rounder" in the field of energy storage.
In terms of full-stack self-research capabilities, as an expert in full-stack service solutions integrating development, investment and operation, it has formed a 3 Cell + 5 Pack + 4 Rack + 13 System standard product system in the field of electric power and industrial and commercial energy storage applications, and on this basis, dozens of products can be customized and developed according to customer needs, which has helped Shandong, Zhejiang, Hubei, Jiangxi and other places to realize the delivery and operation of energy storage projects in multiple scenarios, including smart buildings, smart parks, and power grid sides, and promote local energy transformation.
The National Key R&D Program "Smart Grid Technology and Equipment" is a special project
As one of the enterprises with the most complete energy storage application scenarios in China, Sunwoda Energy Storage continues to lead the technological innovation of the industry and meet the safety and technical pain points of electrochemical energy storage. In 2023, Sunwoda Energy Storage has mastered core technologies and continuously innovated in energy storage cells, Pack, BMS, EMS, system integration, etc., and in 2023, it will successively launch 314Ah large-capacity energy storage cells, and release a series of new products such as industrial and commercial energy storage systems based on 314Ah large-capacity energy storage cells and standard 20-foot 5MWh liquid-cooled energy storage systems.
At the upcoming "12th Energy Storage International Summit and Exhibition" ESIE2024 exhibition, Sunwoda has newly upgraded and released a 5MWh liquid-cooled energy storage system of "high safety + long life + high efficiency", which has been delivered in batches to Zhejiang's largest 200MW/400MWh grid-side energy storage project, putting the latest technological achievements into practical application and injecting strong momentum into promoting local green development.

In terms of comprehensive service capabilities, Sunwoda Energy Storage has an active closed-loop mechanism for full life cycle service response. Strictly implement the closed-loop system of process management of "diversified customer complaint interface", "timeliness of customer complaint response", "textual communication and reporting", "responsibility for processing results" and "standardization of remote support" to provide users with a good service experience. At the same time, Sunwoda Energy Storage relies on the self-developed energy storage cloud platform to create an integrated intelligent operation and maintenance mode of "online monitoring + offline inspection" to realize the active information management of energy storage power stations.
Sunwoda Energy Storage is well aware of the long slopes and thick snow on the energy storage track, and has set up branches in Hong Kong, China, the United States, the United Kingdom, Germany, Italy, Australia, Poland, South Africa, Vietnam, India and other countries and regions, with business in more than 100 countries and regions around the world, gaining a solid market share and first-line market feedback, and fully possessing the ability to go through the painful cycle of the energy storage industry.
In the future, Sunwoda Energy Storage will continue to expand the radius of new energy development, help more regions achieve energy transformation, and draw a green future with the world.
