Breakthrough Silane-Free Silicon Anode Patents for High Energy Lithium-ion Batteries

Rhea-AI Summary

Solidion Technology (NASDAQ: STI) has filed multiple US patent applications for a groundbreaking silicon anode production process aimed at enhancing lithium-ion batteries for EVs. The technology features a silane-free approach to produce graphene-hosted silicon as a high-capacity anode material.

The innovation addresses key limitations of current silicon anode production methods, which rely on expensive and hazardous silane gas. Solidion's solution introduces two major improvements: porous graphene balls capable of holding up to 90% silicon (compared to current 50% limit), and a safer, more cost-effective silane-free silicon precursor.

This advancement is significant as silicon anodes can extend EV driving range by 20-40%, making them important for improving battery performance and reducing costs in the electric vehicle industry.

Positive

• Patent-pending technology could enable 90% silicon content in anodes vs current 50% limit
• New process eliminates need for expensive and hazardous silane gas
• Technology could enable 20-40% increase in EV driving range
• More cost-effective production process

Negative

• Patents are pending, not yet granted
• Technology still in development phase, not commercialized

Solidion files multiple patent applications on a new process to produce graphene ball-hosted silicon anode materials

DALLAS, Feb. 11, 2025 /PRNewswire/ -- Solidion Technology, Inc. (NASDAQ: STI), an advanced battery technology solutions provider, today announced that its technical team has filed several US patent applications on an innovative process for cost-effective production of graphene-hosted silicon as a high-capacity anode material.

Industry-leading EV OEMs have concluded that silicon anode is required to drive EV battery technology to a lower cost and provide a higher energy density, significantly extending the EV driving range. Specifically, silicon (Si) is a leading-edge anode material capable of extending the EV range by 20-40%.

One of globally leading silicon anode materials is produced from chemical vapor deposition (CVD) of Si in pores of highly porous carbon particles. This technology has several major drawbacks, due to the use of a silane gas-based feedstock, which is known to be scarce, highly explosive, costly and challenging to produce, transport, and store. Additionally, current porous carbon particles are incapable of accepting more than 50% of silane-derived Si in their pores, a feature which significantly compromises the achievable cell energy density.

Solidion's patent-pending Si anode technology overcomes these technical and economical obstacles by using an innovative combination of two strategies: (1) well-designed porous graphene balls that can readily accommodate up to 90% Si in the graphene/Si composite and (2) A low-cost silane-free precursor to Si will be much safer to produce, store and transport than silane and can be more cost-effectively converted into Si.
