Solidion Technology, Inc., a prominent global innovator in ultrahigh energy density batteries, has achieved a significant breakthrough in lithium-sulfur (Li-S) battery development. The company's latest Li-S battery has attained an impressive energy density of 380 Wh/kg, with the next target set at 450 Wh/kg. This achievement was recently validated by a leading electric vehicle (EV) battery manufacturer.

Lithium-sulfur batteries are known for their exceptionally high theoretical energy density, exceeding 600 Wh/kg. As a result, Li-S technology is currently the only viable energy storage solution capable of doubling the energy density (260 Wh/kg) of existing lithium-ion cells. One of the key advantages of Li-S batteries is their use of sulfur as the primary cathode material. Sulfur is both abundant and cost-effective, ensuring that the technology remains economically viable.

Unlike conventional lithium-ion batteries, Li-S cells do not require costly and environmentally challenging rare metals such as cobalt, nickel, and manganese. By eliminating these expensive materials, Solidion has positioned itself to deliver batteries at a substantially lower cost. With sulfur's affordability combined with remarkable energy density, battery costs under $65/kWh are now within realistic reach.

This advancement translates to a significant reduction in EV battery expenses. For instance, a 100 kWh battery pack—capable of supporting a 500-mile driving range—is expected to cost around $6,500. This price point closely aligns with the cost of traditional combustion engine systems, making electric vehicles increasingly competitive and accessible even without government subsidies.

Solidion remains committed to addressing key technical challenges that have previously hindered widespread Li-S battery commercialization. The company has introduced innovative solutions, such as graphene/elastomer-protected lithium metal anodes, 3D graphene-protected sulfur cathodes, and quasi-solid or solid-state electrolytes. These advancements significantly enhance battery stability and longevity, accelerating the path to full-scale adoption.

Solidion's technological innovations are backed by a comprehensive intellectual property (IP) portfolio, which includes over 100 US patents along with numerous international patents. This extensive IP protection ensures Solidion maintains its competitive edge in the evolving battery market.

With these groundbreaking developments, Solidion Technology continues to redefine energy storage solutions, setting new benchmarks for performance, cost-efficiency, and sustainability in the EV industry.

Headquartered in Dallas, Texas, with pilot production facilities located in Dayton, Ohio, Solidion's core operations focus on manufacturing battery materials and components. The company also develops and produces next-generation batteries for energy storage systems and electric vehicles across ground, air, and sea transportation.

Solidion boasts a portfolio of over 550 patents, encompassing innovations such as high-capacity, non-silane gas and graphene-enabled silicon anodes, biomass-based graphite, and advanced lithium-sulfur and lithium-metal technologies.
