The constituent stocks, Quartz Co. rose by 10.00%, Hongyuan Green Energy rose by 5.19%, GCL-Poly Energy rose by 3.80%, DeYe Co. rose by 3.64%, and GoodWe rose by 3.49%. The Photovoltaic ETF Ping An (516180) rose by 0.74%, with the latest price reported at 0.82 yuan. In terms of news, on April 6, the team led by Hu Yongsheng from the Institute of Physics, Chinese Academy of Sciences, published significant results in Nature Energy: the team successfully developed a non-flammable electrolyte with self-protection functions (PNE), achieving a complete blockage of thermal runaway in sodium-ion batteries at the ampere-hour level for the first time globally. The team broke the traditional understanding that "flame-retardant electrolytes equal safety," moving beyond a single line of defense to construct a "thermal stability - interface stability - physical isolation" trinity of intelligent safety protection systems. When the battery temperature rises abnormally above 150°C, the PNE automatically solidifies from liquid to a dense barrier, akin to building an "intelligent firewall" inside the battery, completely cutting off the propagation path of thermal runaway. CITIC Securities' research report indicates that the 14th International Energy Storage Summit and Exhibition ESIE 2026, held in Beijing from April 1 to 3, 2026, attracted over 800 manufacturers to participate, with a noticeable rebound in exhibition enthusiasm. In this exhibition, large-capacity battery cells, sodium-ion batteries, and AIDC solutions became the focus of various manufacturers. CITIC Securities believes that with the cancellation of mandatory storage by Document No. 136 from the National Development and Reform Commission and the establishment of a national-level capacity pricing mechanism by Document No. 114, domestic energy storage will shift from cost priority to value creation, improving the competitive landscape. They recommend leading manufacturers in the energy storage industry chain, including battery cells, PCS, and integration. The Photovoltaic ETF Ping An closely tracks the CSI Photovoltaic Industry Index, which selects no more than 50 of the most representative listed company securities involved in the upstream, midstream, and downstream of the photovoltaic industry chain as index samples to reflect the overall performance of listed company securities in the photovoltaic industry. Data shows that as of March 31, 2026, the top ten weighted stocks in the CSI Photovoltaic Industry Index (931151) are TBEA, LONGi Green Energy, Sungrow Power Supply, TCL Technology, DeYe Co., Tongwei Co., Maiwei Co., Robotech, Chint Electric, and Jiejia Weichuang, with the top ten weighted stocks accounting for a total of 53.34%.
