Meilian New Materials' controlled subsidiary, Anhui Meixin, has successfully mastered the technology for semi-solid battery separators and has garnered small batch orders. Furthermore, through its grandchild company, Huihong Technology, it produces Prussian blue cathode materials tailored for solid-state or semi-solid sodium-ion batteries. Currently, Meilian New Materials' solid-state battery business is in an expansive research and development phase, contributing a modest portion to overall revenue.
