Jiangsu Yiruida Composite Materials

Battery-cell protection

The materials address heat transfer between cells in electric-vehicle and energy-storage batteries. Yiruida combines graphene, radiation-shielding powders and high-temperature inhibitors to limit heat conduction, radiation and convection.

From research to manufacturing

The business commercializes research from the Chinese Academy of Sciences’ Suzhou Institute of Nano-Tech and Nano-Bionics. It established production in Xinghua, Jiangsu, with backing from Taizhou Angel Investment Fund and Lize Fund.

Production and financing

An initial production run served a Taiwanese customer in November 2024. A later government update said the first line entered stable operation in February 2025 and the company was building a second automated line.

The two funds invested a combined CNY10 million in an angel financing completed in July 2024. Xinghua authorities disclosed the investment in December 2024.
