May 15, 2026 - Shenzhen, China – The global battery industry is experiencing an unprecedented period of growth and innovation in 2026, driven by technological breakthroughs in lithium-ion, solid-state and sodium-ion batteries, rising demand for electric vehicles (EVs) and energy storage systems, and the ongoing global energy transition. The 18th China International Battery Fair (CIBF 2026), which kicked off in Shenzhen from May 13 to 15, has become a showcase for these industry advancements, attracting over 3,000 exhibitors worldwide and highlighting the sector’s dynamic development trajectory.
A series of key technological breakthroughs have laid a solid foundation for the industry’s rapid development. In February 2026, a research team jointly formed by Nankai University and the Shanghai Space Power Research Institute achieved an innovative breakthrough in electrolyte technology. By developing a new type of fluorinated hydrocarbon solvent molecule, the team successfully solved the key problem of fluorine’s difficulty in dissolving lithium salts, significantly improving the energy density and low-temperature performance of lithium-ion batteries. This achievement, published in the international academic journal Nature, enables existing lithium-ion batteries to double their endurance while maintaining the same size and weight, with enhanced adaptability to low-temperature environments.
Meanwhile, solid-state and sodium-ion batteries are accelerating their commercialization进程, becoming new growth engines for the industry. In 2026, more than 16 key solid-state battery projects in China have entered the substantive promotion stage, with companies such as Weilan New Energy and Guoxuan High-Tech investing heavily in industrial parks and production lines. It is widely believed that 2026 will be a crucial turning point for solid-state batteries to move from R&D to industrialization. In the sodium-ion battery sector, CATL launched its mass-produced sodium-ion battery product "Naxin" in 2026, with an energy density of 175 Wh/kg and a capacity retention rate of 90% at -40℃. In late April, CATL signed a 3-year, 60 GWh sodium-ion battery strategic cooperation agreement with Haibosi Chuang, the world’s largest order of its kind, marking the official entry of sodium-ion batteries into large-scale application.
The global battery market is also showing strong growth momentum. It is estimated that the global battery market size will reach 1.5 trillion US dollars in 2026, with a compound annual growth rate of over 25%. Among them, power batteries account for 62%, energy storage batteries 28%, and consumer electronics batteries 10%. The rising penetration rate of new energy vehicles, the growing demand for renewable energy grid connection, and the intelligent upgrading of consumer electronics are the three core drivers of market growth. In terms of market competition, Chinese enterprises occupy 58% of the global market share, forming a tripartite pattern with South Korean and Japanese enterprises. CATL and BYD, as leading Chinese battery manufacturers, have obvious advantages in technological R&D, production capacity scale and cost control.
However, the industry also faces challenges such as the rebound in lithium carbonate prices. As of May 11, 2026, the spot price of battery-grade lithium carbonate has approached 190,000 yuan per ton, with an annual increase of nearly 60%, forcing upstream material enterprises to accelerate technological innovation to reduce lithium dependence. Enterprises such as GCL Lithium and Longpan Technology have launched new technologies and materials to reduce production costs and improve energy density, effectively responding to cost pressure.
Industry experts predict that the battery industry will enter an accelerated period of technological iteration after 2026, with green low-carbon, intelligence and globalization becoming the core development directions. The whole industry chain’s carbon neutrality has become a consensus, and the carbon emission in the battery production process is expected to decrease by 40%; the intelligent upgrading of battery management systems and the application of AI technology will shorten the R&D cycle by 30%; at the same time, the global supply chain will be restructured, and the proportion of overseas production capacity of leading enterprises will continue to rise. With the continuous deepening of industrialization, China is accelerating its transformation from a "battery power" to a "battery powerhouse", leading the global new energy industry revolution.
