A Ranking of the Top 50 Domestic Solid-State Battery Companies

China’s tech industry is at a historic turning point! The latest 2025 Fortune China Top 50 Tech Companies list has just been released. Huawei once again tops the list, thanks to its breakthroughs across the entire technology chain. AI company DeepSeek has surged into second place, while CATL firmly maintains its position as the leader in the new-energy sector. Even more exciting is that four major sectors—semiconductors, solid-state batteries, energy storage, and robotics—are experiencing a collective boom. A wave of cutting-edge tech companies is now transitioning from “domestic substitution” to “global leadership.”

This transformation is not only reshaping the global tech landscape but will also profoundly impact everyone’s daily life—from the smartphone in your hand to fully autonomous vehicles of the future, from home energy storage systems to smart robotic butlers. Chinese technology is quietly emerging as the world’s engine of innovation.

Cooperating enterprises are rising in tandem. Luxshare Precision provides precision structural components for Huawei’s smartphones; OFILM exclusively supplies lenses for the Mate 70 series; and Runhe Software and Softcom Dynamics are deeply involved in the development of the HarmonyOS ecosystem. In the broader domestic semiconductor sector, SMIC has achieved a 95% yield rate for its 14nm process, and its 7nm process has entered risk production; Zhongwei Company’s etching equipment technology is internationally leading; and Changdian Technology ranks among the top three globally in terms of packaging and testing capacity. Together, these companies form the backbone of China’s chip self-reliance.

Solid-State Batteries: The Industrialization Turning Point Has Arrived—CATL Sets Another Record.

2025 is set to be a pivotal year for the commercialization of solid-state batteries. CATL has unveiled a solid-state battery with an energy density of 500 Wh/kg, reducing charging time to just 10 minutes. Meanwhile, sodium-ion batteries have achieved an energy density of 175 Wh/kg, with costs 30% lower than those of lithium-ion batteries. These technological breakthroughs are sparking a ripple effect throughout the industry chain: The Institute of Physics at the Chinese Academy of Sciences has overcome key challenges in the interface of all-solid-state battery electrolytes; EVE Energy’s “Longquan No. 2” all-solid-state battery has rolled off the production line, boasting an energy density of 300 Wh/kg; and SAIC Motor announced that it will launch vehicles equipped with all-solid-state batteries by 2027.

Semi-solid-state batteries are taking the lead in scaling up production. In 2024, shipments will enter the gigawatt-hour level and find applications in high-end consumer products and autonomous vehicles, among other fields. Enjie Shares has already begun mass-producing separators for semi-solid-state batteries, while Ganfeng Lithium is advancing vehicle integration testing of lithium-metal anode batteries. Industry forecasts predict that global solid-state battery shipments will reach 614 GWh by 2030, with all-solid-state batteries accounting for nearly 30% of the total. This technological revolution is driving the entire industry chain to upgrade: cathode materials are evolving toward high-nickel ternary and lithium-rich manganese-based compositions; anode materials are shifting—from silicon-carbon in the medium to short term—to lithium metal; and solid-electrolyte materials are seeing fierce competition among four major approaches: sulfides, oxides, and polymers.

China’s energy storage industry has now established a complete ecosystem, and in 2023, the output value of new energy storage technologies exceeded 300 billion yuan. By 2030, cumulative installed capacity is expected to reach 220 GW, with the industry’s total output value surpassing 3 trillion yuan. Thanks to its global market shares of 37.6% in power batteries and 32% in energy storage systems, CATL has become a leader in both sectors. Its energy storage products are deployed in over 50 countries, supporting grid peak-shaving projects. The Xieyao hybrid battery released in 2024 offers a pure-electric range of 400 kilometers and can add 280 kilometers of range with just 10 minutes of charging.
