Analysis of the Strong Performance of 300619 Jinyinhe: Dual Drivers from Solid-State Batteries & Rubidium Cesium Salts and Performance Support

300619 Jinyinhe (Foshan Jinyinhe Intelligent Equipment Co., Ltd.) is a listed company in the power equipment sector, focusing on new energy material equipment manufacturing [2][3]. On November 27, 2025, the stock rose by 15.6% in a single day and entered the strong stock pool [0]. Its strong performance is mainly supported by three factors:

1. Catalysis from the solid-state battery industry chain
   : The solid-state battery concept has been rising recently, and the industry chain is expected to enter a critical pilot period from 2026 to 2027. As an equipment supplier, the company directly benefits [1][5];
2. Breakthrough in rubidium cesium salt business
   : The company’s rubidium cesium salt products have been sold, and it has built the world’s largest rubidium cesium production base, becoming a new growth engine [4][5];
3. Performance turnaround
   : The first three quarters’ performance turned from loss to profit, verifying the effectiveness of the dual-driven business model of solid-state battery equipment and rubidium cesium salts [5];
4. Overall upward trend of the industry
   : The new energy sector (including lithium batteries and energy storage) has entered a new upward cycle, further boosting the performance of individual stocks [7].

1. Cross-domain synergy
   : The solid-state battery equipment and rubidium cesium salt businesses form a synergistic effect, benefiting from new energy technology iteration and expanding into high-value-added new material fields [5];
2. Industry positioning advantage
   : The company’s leading position in solid-state battery equipment and rubidium cesium salt fields gives it an advantageous position in the industrial chain upgrade [1][4];
3. Performance verification logic
   : The turnaround from loss to profit breaks the market’s doubts about the company’s transformation and provides fundamental support for valuation repair [5].

• The pilot phase of the solid-state battery industry chain from 2026 to 2027 will bring an explosion in equipment demand [1];
• The rubidium cesium salt market has great potential, and the company’s leading position is expected to continue to expand its share [4];
• The upward cycle of the new energy sector continues, and the valuation improvement of the sector drives individual stocks [7].

• The industrialization progress of solid-state battery technology is less than expected, affecting the landing of equipment orders [1];
• Increased market competition for rubidium cesium salt products and price fluctuation risks [4];
• Changes in macroeconomics and policies may lead to valuation fluctuations in the new energy sector [0].

The strong performance of 300619 Jinyinhe is the result of the combined effect of fundamental improvement (turnaround from loss) and industry catalysis (solid-state batteries, new energy upward trend). Future focus should be on:

1. The pilot progress of the solid-state battery industry chain and the company’s equipment order situation;
2. The sales scale and profit contribution of rubidium cesium salt products;
3. Changes in the overall trend of the new energy sector.
