Policy Interpretation | 60 million bet on humanoid robots! How can Wuhan battery companies take advantage of favorable policies?

2025-06-25

Wuhan's "Three-Year Action Plan for Innovation and Development of the Humanoid Robot Industry", released on June 13, clearly states that it will provide subsidies of up to 60 million yuan for the development of complete machines and a 30% reward for the purchase of components based on the actual amount. Although the policy does not explicitly mention "batteries", humanoid robot batteries, as core components, fully meet the policy's applicable conditions for "components" and "product providers". Relevant companies can apply for funding support through three types of projects: "procurement subsidies", "leading the charge", and "scenario rewards".

What are the bottlenecks in the mass production of solid-state batteries? How can dry-film electrode technology overcome the two major challenges of coating cracks and solvent residue?

2025-06-10

Solid-state battery materials are currently a core bottleneck hindering the commercialization of all-solid-state batteries due to issues such as high interfacial impedance, uneven electrolyte coverage, and difficulties in mass production. Currently, innovation in electrode manufacturing processes is the key to breaking through this bottleneck. Traditional wet processes face problems such as solvent residue and interfacial cracks in solid-state electrolyte coating, while dry processes are becoming the industry focus due to their advantages of being solvent-free and highly compatible.
