The global supply of cesium is expected to be less than 40 tons in 2024, with prices reaching 4 million yuan per ton [1][2] - The global demand for cesium and rubidium is clearly on the rise, driven by three main factors: consumption structure upgrades in China, the explosive demand from perovskite solar cells, and improvements in rubidium supply [2][9] Group 2 - In 2020, global cesium consumption was 2,400 tons, with the United States (960 tons, 40%), China (800 tons, 33%), and Japan (300 tons, 14%) being the main consumers. The U.S. consumption is concentrated in high-tech fields (80%), while China's is primarily in traditional sectors (89%) [2][25] - By 2025, China's cesium demand is expected to reach 1,016 tons, a 27% increase from 2020, driven by advancements in atomic clocks and ion thrusters alongside the development of 5G and aerospace [2][36] - The global cesium and rubidium salt demand is projected to grow from 2,466 tons in 2025 to 4,600 tons in 2027, with a compound annual growth rate (CAGR) of 36.6% [9][50] Group 3 - The supply side is dominated by leading companies, with Zhongmin Resources controlling over 80% of global cesium lepidolite resources. By Q3 2025, the total production capacity is expected to reach 1,500 tons, accounting for over 50% of global capacity [3][10] - The global supply of cesium and rubidium salts is expected to be 2,210 tons in 2025, 3,135 tons in 2026, and 4,550 tons in 2027, indicating a gradual narrowing of the supply-demand gap [10][50] - The report recommends companies such as Zhongmin Resources and Jinyin Galaxy as key players in the cesium and rubidium industry [11][56]
