Solidion Technology Inc. announced its plan to begin expanding the production capacity of silicon-rich graphene composite materials in early 2025. The amount of energy that a lithium-ion battery can supply to an electric vehicle (EV) is limited by the amount of charges stored in its anode and cathode materials. Although graphite has been the preferred anode material during the past 30 years, silicon oxide (SiOx) and silicon (Si) are two evolving anode materials capable of improving the energy density of EV batteries and extending the EV range by 20-40%.

However, the higher-capacity gain of both silicon and silicon oxide is limited by the technical issue of large volume change-induced rapid capacity decay and processing difficulty. Solidion has overcome this technical obstacle and has established a Dayton, Ohio-based facility for manufacturing silicon oxide (SiOx)and silicon (Si). The Solidion team is ready to expand the production capacity for these two types of high-capacity anode materials.

Industry-leading EV OEMs have concluded that silicon and silicon oxide anodes are required to drive EV battery technology to lower cost and provide higher energy density, significantly extending the EV driving range. Solidion's innovative Si anodes can deliver this technology and more as a drop-in solution. This has been recently validated by a third-party, which provides the following comments: "This coating went surprisingly well.

In all of the silicon work that we've done this year, we've not had a single coating that goes well." 2) "You didn't see any streak or see any agglomeration through the whole coating. The coating thickness dialed in very quickly. It's almost like coating graphite." So I think it's a huge advantage of your material." Solidion is well-positioned to become a leading North American supplier of battery anode materials, including graphite from sustainable sources, silicon oxide (SiOx), and silicon (Si).

Solidion's predecessor company (G3) was recognized as a global leader in the patent landscape of silicon anode for lithium-ion batteries.1 This report ranked G3 No. 1 in the USA in terms of Si anode patent portfolio. Among US-based companies, G3 was No.

1 (having 131 patent families in the Si anode), followed by GM (90) and two other US-based battery start-ups in the world. Solidion has developed anode materials which precisely fulfill requirements for next-generation EV batteries now specified by the industry. Solidion seeks to establish partnerships for expanding manufacturing capacity of its advanced anode materials.
