On July 24, Shaanxi Ruizhi New Energy Technology Co., Ltd. (hereinafter referred to as "Ruizhi new energy"), an investment enterprise of Xijiao 1896, announced that it had completed the pre-A round of financing of tens of millions of yuan, which was led by the green materials investment fund of Shaanxi Financial Investment and financing company. This round of financing will focus on technology research and development, production equipment procurement and infrastructure upgrading, help the company achieve capacity jump and technology iteration, and accelerate its march towards the core supplier of the solid-state lithium battery industry chain.
Ruizhi new energy is a leading manufacturer of "solid electrolyte membrane" and "functional separator" for batteries. It focuses on material R&D capability and takes "high safety performance" as the innovation goal to improve the performance of various types of new energy batteries (liquid/semi-solid/all solid) in "high energy density" and other diversified fields. The company focuses on the R&D and engineering application of new electrochemical materials in the field of solid-state lithium batteries. At present, the first generation of active functional diaphragm has achieved stable mass production and can be widely used in power batteries, energy storage systems and consumer electronics; Breakthrough progress has been made in the research and development of quasi/all solid electrolyte membrane at the scale of the second generation high specific energy cell, with key performance indicators reaching the industry-leading level and testing and certification of several head battery enterprises completed; In addition, the second generation lithium-ion battery lithium-ion film has successfully achieved the matching application of the lithium-ion film and the mainstream ternary cell system. The material suitability, coating process validation and cell level test have been completed, and it is ready for mass production.
Technological breakthrough: second generation products:
The first generation of active functional diaphragms: stable mass production has been achieved, and the three-dimensional lithium conducting network has been built through nano coating technology, which is widely used in power batteries, energy storage systems and consumer electronics. The product still maintains structural integrity under the extreme environment of 180 ℃, and its thermal runaway inhibition ability is significantly better than that of the traditional diaphragm. A supply intent agreement of 50million square meters has been signed, and the output value is expected to reach 100million yuan in 2025.
The second generation of quasi/all solid electrolyte membranes: breakthroughs have been made in research and development, and key performance indicators have reached the industry-leading level. Its self-developed SCS series products use polymer ceramic composite substrate to achieve mechanical strength under ultra-thin thickness of 10 μ m, with room temperature ionic conductivity of 0.5 × 10 ? s/cm and interface impedance reduced by 50% compared with the industry average level. The product has passed the test and certification of Ningde times, GuoXuan high tech and other head battery enterprises, and has entered the stage of small batch production.
In addition, the second generation lithium battery lithium supplement film: it has successfully realized the matching application with the mainstream ternary cell system. Through the "lithium ion compensation" technology to solve the problems of high cost and complex process of traditional lithium supplement process, it can improve the battery cycle life by 10% -20% and energy capacity by 3% -7%. Relevant material suitability, coating process validation and cell level test have been completed, and the conditions for large-scale mass production are available.
With the formal production of the diaphragm production base in Fengdong new town, Ruizhi new energy has an annual production capacity of 10million square meters. It plans to start Anhui phase II project in Q3 2025, add 2-4 production lines, and the annual output value is expected to exceed 500million yuan. The yield of its semi-solid diaphragm production line has continued to improve, and its products have been supplied to the head power battery enterprises in batches. In June, the output increased significantly year-on-year, and the market share has steadily expanded in power batteries, energy storage and other fields.
The global solid-state battery market is entering an explosive period. It is estimated that the market size will reach 18billion US dollars in 2025 and exceed 100 billion US dollars in 2030. Ruizhi new energy has the first mover advantage in the competition by virtue of the technical reserves and mass production capacity of three generations of products. Its technical route covers the three main directions of oxides, sulfides and polymers, with more than 10 patents. It has been highly praised by industry authoritative experts, saying that it "provides a new solution for improving battery safety and energy density".
In the future, Ruizhi new energy will build a collaborative development pattern of "technology research and development - capacity implementation - market expansion", continue to improve its core competitiveness through the construction of standardized management system and digital transformation, and aim to become a core supplier of the global solid-state lithium battery industry chain. Driven by both policy support and market demand, its technological breakthroughs and capacity release are expected to inject new momentum into the development of the industry.
