Chinese tech startup i2Cool has raised tens of millions of yuan in a Series B funding round led by TopoScend Capital, aiming to scale production of its innovative passive radiative cooling materials and expand into priority international markets.
- Raised several million USD in Series B financing
- Focus on passive radiative cooling nanoparticles
- Backlog of CNY 120 million and global reach in 30+ countries
What happened
i2Cool Shenzhen Limited, founded in 2022, closed a Series B investment round worth tens of millions of yuan, led by Shenzhen TopoScend Capital. Linglu Capital acted as the exclusive financial adviser during this fundraising. The funding will be deployed to develop standardized nanoparticle production lines, advance core technologies, attract key personnel, and expand commercial operations internationally.
The company specializes in electricity-free passive radiative cooling materials and has developed a scalable manufacturing capability for functional nanoparticles. These materials can be applied across coatings, textiles, automotive finishes, and building materials. The founding team is highly experienced, with leaders including two prominent academics from Hong Kong recognized for their contributions to energy and sustainability research.
Why it matters
i2Cool’s proprietary technology uses nanoparticles designed for full-spectrum thermal management by reflecting sunlight and emitting heat through the atmospheric window, achieving solar reflectivity and mid-infrared emissivity above 95%. This provides passive cooling without the energy consumption and environmental issues associated with electric air conditioning systems.
The technology enables applications that can reduce building and material heat gain sustainably, contributing to energy savings and carbon reduction goals globally. The company’s ability to customize colors and incorporate adaptive features without compromising cooling performance makes the technology versatile across markets, helping it secure orders exceeding CNY 120 million.
What to watch next
i2Cool plans to scale up its production capabilities with the new capital to meet growing demand and increase its presence particularly in the Middle East and Southeast Asia, where climatic conditions favor deployment of passive cooling solutions. The company’s backlog of over 500 projects and surface coverage above one million square meters demonstrates strong commercial traction to build upon.
Investors and market observers should track how i2Cool leverages AI-driven materials science for further efficiency gains in R&D and how it manages international expansion amid increasing global demand for sustainable cooling technologies. Partnerships, new product launches, and entry into additional overseas markets will be key indicators of its growth trajectory.
