China's Ministry of Industry and Information Technology (MIIT) released the New-type Energy Storage Technology Development Roadmap (2025-2035) on Wednesday at the main forum of the World Energy Storage Conference 2025, providing guidance and reference for further promoting high-quality industrial development and high-level industrial security.
This roadmap focuses on five key subfields: electrochemical energy storage, mechanical energy storage, electromagnetic energy storage, cold thermal energy storage, and hydrogen storage. It outlines key products, essential materials and components, as well as development goals for various fields leading up to 2035.
"From a national perspective, the roadmap systematically evaluates the development status of different technology industrial chains. On the enterprise level, it also presents specific indicators for product development and outlines future development direction," said Zhang Yanli, associate researcher at the Equipment Industry Development Center of the MIIT.
Currently, the country's new-type energy storage technologies are developing rapidly, with a surge of innovative achievements emerging.
A newly released energy storage system in China is the world's first to achieve zero degradation over five years and can be mass-produced on a large scale. It boasts a storage capacity of 6.25 megawatt-hours (MWh) of high energy within a single 20-foot container, with energy density increased by 30 percent.
Meanwhile, the application scenarios for new technologies are also continuously expanding. At present, Shanghai's Mingdong Container Terminal, a key hub for global trade, is undergoing new energy transformation of fuel equipment.
"Custom battery packs have been specifically developed, featuring an electrophoretic powder coating and painting process on the battery housing, making them fully capable of withstanding the high-salinity and high-humidity environment of the port," said Zhou Gong, product engineer at China's CATL, the world's largest battery maker.
In the first half of this year, the country's installed capacity of new-type energy storage had reached 94.91 million kilowatts, representing an increase of approximately 29 percent compared to the end of 2024.

Chinese scientists announced Monday that they have achieved a breakthrough in yak cloning, with 10 cloned calves all naturally delivered in southwest China's Xizang Autonomous Region.
These calves, consisting of three black yaks and seven white ones, were born from March 25 to April 5 at a yak breeding and research base in Xizang's Damxung County, all meeting expected standards and steadily gaining weight.
The mass births came after the first cloned yak was born in July 2025, which has grown healthily and weighs about 183 kg now.
The achievement was made using a domestically developed breeding system that combines whole-genome selection with somatic cell cloning, following three years of research by a Chinese scientific team.
"Whole-genome selection can accurately pinpoint excellent genetic loci associated with large body size, fast growth, strong fecundity and disease resistance, high feed conversion efficiency, and tolerance to high-altitude and low-oxygen conditions (cold resistance). On this basis, somatic cell cloning enables 1:1 precise replication of the genotype through asexual rapid propagation (cloning), thereby compressing the breeding cycle to within five years," said Fang Shengguo, a professor at the College of Life Sciences at Zhejiang University and director of the State Conservation Center for Gene Resources of Endangered Wildlife.
Yak farming is one of the key industries targeted for development in Xizang during the country's 15th Five-Year Plan period (2026-2030). Traditional yak breeding has relied on phenotype selection, a process that can take up to 20 years and often leads to declining genetic quality.
Researchers said the new method can shorten the breeding cycle to less than five years by accurately identifying desirable genetic traits such as faster growth, disease resistance, feed efficiency and adaptation to high-altitude, low-oxygen environments, while enabling rapid replication of elite breeding stock.
Experts added that the technology could also support conservation efforts for rare yak genetic resources, including the endangered golden wild yak, whose population in Xizang is estimated at more than 300.
So far, the research team has developed more than 200 cloned embryos of golden wild yaks and hybrid wild-blood yaks, laying the groundwork for future embryo transfer and species recovery programs.
