Solid-state battery materials make a new breakthrough! The ChiNext 50 ETF leads similar products, with a trading volume exceeding 1.2 billion yuan, ranking first.

On January 30th, the Shanghai Composite Index regained the 4100-point level in early trading, while the ChiNext Index bottomed out and rose by 0.80%. In this context, the ChiNext 50 ETF rose by 1.42% to 1.569 yuan, with a turnover rate of 5.09% and a trading volume of 12.12 billion yuan, ranking first among similar ETFs. In terms of news, the Qingdao Energy Institute of the Chinese Academy of Sciences recently successfully developed a high-performance silicon negative electrode material for sulfide all-solid-state batteries, demonstrating excellent electrochemical properties such as high Coulomb efficiency, low expansion rate, and long cycle stability. The material has a specific capacity of 2267mAh/g, with a volume expansion rate of only 37.8% after 50 cycles, far lower than the 300% of pure silicon materials; after 1000 cycles at room temperature, the capacity retention rate still reaches 81.7%. Dongguan Securities pointed out that with its ultra-high specific capacity and excellent fast charging performance, silicon-based negative electrodes have become one of the key materials for next-generation high-energy density batteries. Looking ahead, Guotai Junan Securities believes that there is still significant room for China's "transformation bull", with reform and transformation as the main long-term themes. As concerns about "internal and external troubles" gradually ease in the market, A-shares are expected to undergo a value reassessment. In terms of investment opportunities, technology growth remains the main direction, while also focusing on the transformation opportunities in cyclicals and consumer sectors, with value stocks also having allocation space. Investors can trade the ChiNext 50 ETF directly through a stock account or participate through linked funds.
