The Energy Storage Battery ETF E Fund (159566) tracks the CNI New Energy Battery Index and has continued to see capital inflows. As of the previous trading day, the fund had a net inflow of 2.871 billion yuan over the past month, 3.289 billion yuan over the past three months, 5.502 billion yuan over the past six months, and 6.954 billion yuan over the past year.

On the technical front, China's sodium-ion battery technology has made a major breakthrough. On April 6, a research team from the Institute of Physics, Chinese Academy of Sciences, published their findings in an international journal: the team successfully developed a polymerized non-flammable electrolyte (PNE) with self-protection functions, achieving complete thermal runaway blocking in ampere-hour level sodium-ion batteries for the first time globally.

At the industry level, the 14th Energy Storage International Summit and Exhibition (ESIE 2026) was recently held in Beijing. Judging from the exhibitors, the exhibits covered the entire energy storage industry chain, including materials, cells, PCS, BMS, temperature control and fire protection, system integration, EPC, operation and other segments. It is reported that the participation enthusiasm at this event was higher than in 2025.

CITIC Securities pointed out that during this exhibition, large-capacity cells, sodium-ion batteries, and AIDC solutions became the focus of exhibitors. With the NDRC's Document No. 136 canceling mandatory energy storage allocation and Document No. 114 establishing a national capacity price mechanism, domestic energy storage will shift from cost priority to value creation, and the competitive landscape is expected to improve.

The Energy Storage Battery ETF E Fund (159566) tracks the CNI New Energy Battery Index, which selects 50 listed companies in related fields such as battery manufacturing, energy storage battery inverters, energy storage battery system integration, and battery temperature control and fire protection.
