Continue to provide users around the world with more professional and more adapted to local needs products and services.

In particular, with the rapid expansion of the scale of the energy storage industry, the electricity of single energy storage power stations has moved from 100 MWh to the GWh era, putting forward higher requirements for battery performance, and large-capacity batteries have become a major direction for the upgrading and development of the industry. Based on this, Haichen Energy Storage released the world's first dedicated battery for long-term energy storage. It has done a lot of work in three aspects: chemical system, cell structure, and manufacturing process, and has "jumped" the battery capacity to 1130Ah, and will be Global delivery will be launched at the end of this year. "Take a 1GWh energy storage power station as an example. If it is equipped with 280Ah batteries, its number will exceed 1 million. From batteries, individual energy storage products, to the monitoring and management of the entire power station, they all face great challenges." Li Weiming of Haichen Energy Storage Product Management Department introduced that compared with 280Ah energy storage battery products, the integrated efficiency of the energy storage system using MIC 1130Ah has been increased to 35%, comprehensively simplifying the system integration complexity, and the comprehensive cost of the DC-side energy storage system reduced by 25%. "Energy storage products are not simply scaled up, but are developing in a safer, more reliable and higher value direction."

Make the ultimate product

There are many participants in the field of lithium battery energy storage. If you want to make differentiated advantages, you must work hard to make the products to the extreme.

Liao Linping, the negative electrode formulation development manager of Haichen Energy Storage, was one of the earliest employees of Haichen Energy Storage. Talking about the entrepreneurial process, she started talking,"The lithium battery binder I am engaged in research and development is a polymer material that adheres electrode active materials to the current collector to improve the electrochemical performance and stability of the battery. Understanding it requires not only spatial imagination, but also rich knowledge of fluidics, physics and electrochemistry, which is extremely challenging. In the early days of its founding, the company did not have a laboratory or even a decent experimental table. We were ordered to lay a layer of oil paper on the ground and put the mixer on top of it to start the test. Through continuous efforts, the properties of the adhesive are continuously optimized, and the product has good wettability and compatibility." Liao Linping took photos of the simple test scenes at that time, collected them, and occasionally took them out to show them to everyone, reminding the team not to forget their original intention-"Now that we use advanced experimental equipment, we must make the ultimate products."

Lithium battery energy storage is a sophisticated advanced manufacturing industry, covering multiple disciplines such as electronic power, automatic control, chemical materials and information technology. It is inseparable from strong "intellectual support" and "industrial chain support."

Focus on energy storage tracks and strive to be a pioneer benchmark for high-quality development. Wang Pengcheng, co-founder and president of Haichen Energy Storage, introduced that currently, Haichen Energy Storage employs Sun Shigang, academician of the Chinese Academy of Sciences, as the chief scientist, and integrates 11 units from universities, scientific research institutes and leading upstream and downstream enterprises in the industrial chain to form the Xiamen City Advanced Electrochemical Energy Storage Technology Innovation Consortium. The innovation consortium will start from the application needs of energy storage scenarios, focus on high specific energy, high safety, long cycle life, low cost and intelligence, achieve comprehensive performance breakthroughs in energy storage batteries and system products, and consolidate the regional energy storage industry chain. Ecological development. Recently, eight units including the Ministry of Commerce, the Ministry of Industry and Information Technology, and the Ministry of Ecology and Environment released the third batch of national supply chain innovation and application demonstration cities and demonstration enterprises list. Haichen Energy Storage became the first energy storage battery company selected in Fujian Province.

In Wang Pengcheng's view, the core issues in the development of the energy storage industry are safety and cost. Without safety, the smooth operation of the new power system will not be fundamentally guaranteed; without economy, the business model will not work, and energy storage will remain in the demonstration stage. In the final analysis, the actual competition between safety and cost is the comprehensive strength of battery companies in product research and development, material development, manufacturing capabilities, recycling systems, etc.

Li Guodong, head of the Haichen Energy Storage Quality Management Center, said that focusing on pursuing the "zero defect" quality goal, focusing on the three major challenges of safety, economy and standardization faced by energy storage, combined with Haichen Energy Storage's own requirements, we strive to achieve "zero defect" goal.

Lithium battery energy storage represents mankind's commitment to energy storage. The cutting-edge scientific research direction; secondly, it has the characteristics of "high efficiency". Lithium battery production raw materials are widely available, the production process is intelligently manufactured, and production emissions can be recycled. It is a typical example of a zero-carbon supply chain. Taking intelligent manufacturing as an example, all production links, quality control, product traceability and other aspects in the front, middle and back stages are characterized by automation, intelligence and data; finally, they are characterized by "high quality". Lithium batteries have become one of the "three new things" for foreign trade exports. China has the most complete energy storage industry chain and industrial technology in the world, and is the most representative industry for building Chinese creations, Chinese quality, and Chinese brands.

"New quality productivity points out the direction for the development of new energy storage advanced productivity. "Wang Pengcheng pointed out that Haichen Energy Storage will forge a leading new quality productivity in global energy storage through new quality cognition + new quality values + new quality innovation.
