Ion Storage Systems is a leading innovator in the energy storage industry, headquartered in Beltsville, Maryland. The company specializes in the development and commercialization of solid-state lithium metal batteries, a technology that promises to redefine energy storage with its focus on safety, efficiency, and sustainability. Founded by Eric Wachsman, a Distinguished University Professor at the University of Maryland, and Greg Hitz, a materials science and engineering expert, Ion Storage Systems has quickly established itself as a pioneer in the battery sector.
The company’s mission is to transform energy storage by addressing the limitations of traditional lithium-ion batteries. By leveraging its patented solid-state battery technology, Ion Storage Systems aims to provide safer, faster-charging, and more cost-effective solutions for a wide range of applications, including electric vehicles, consumer electronics, aerospace, defense, and grid storage. With a strong emphasis on innovation and scalability, the company is about to play a significant role in the global transition to cleaner energy systems.
Battery Technology
Ion Storage Systems is best known for its advanced solid-state lithium metal battery technology, which offers several advantages over conventional lithium-ion batteries. At the core of its innovation is a patented anodeless design that eliminates the need for graphite and other less sustainable materials, reducing environmental impact and enhancing safety. The company’s batteries feature a unique 3D ceramic structure that acts as both a separator and a protective layer, preventing dendrite growth and self-discharge mechanisms. This design not only improves energy density but also eliminates the risk of thermal runaway, a common issue with traditional lithium-ion batteries.
One of the standout features of Ion Storage Systems’ technology is its compressionless design. Unlike many solid-state batteries that require external pressure to function, Ion’s batteries operate without compression, simplifying manufacturing and reducing costs. This innovation also eliminates the need for additional cooling systems or heavy fire barriers, making the batteries more compact and lightweight.
The company’s solid-state electrolyte is nonflammable, further enhancing safety and reliability. This makes the batteries ideal for high-demand applications such as electric vehicles, where fast charging and long cycle life are critical. Ion Storage Systems’ batteries have demonstrated the ability to achieve 800 cycles without significant degradation, meeting and exceeding industry standards. Additionally, the technology is compatible with a variety of cathode materials, allowing for flexibility in design and application.
Recent Projects
In recent years, Ion Storage Systems has made significant progress in scaling its technology and expanding its market presence. In 2024, the company commissioned one of the largest solid-state battery manufacturing facilities in the U.S., located in Beltsville, Maryland. This facility is expected to produce 1 MWh of battery cells initially, with plans to scale up to 10 MWh by early 2025 and 500 MWh by 2028. The expansion is expected to create skilled manufacturing jobs and strengthen Maryland’s position as a hub for clean energy innovation.
The company has also secured notable funding to support its growth. In November 2024, Ion Storage Systems received a $10 million debt investment from Leonid Capital Partners, aimed at accelerating the development and market delivery of its solid-state battery technology. Additionally, the state of Maryland announced an $11 million investment in the company as part of its strategy to boost advanced manufacturing and clean energy initiatives.
Investors
Ion Storage Systems has attracted significant investment from a diverse group of backers. Key investors include Clear Creek Investments, VoLo Earth Ventures, Alsop Louie Partners, Toyota Ventures, and Tenaska. The company has also received funding from Bangchak Corporation, GAINTECH Capital, Alumni Ventures Group, Z2Sixty Ventures, and Climate Capital. In addition to venture capital, Ion Storage Systems has secured grants from the U.S. Department of Energy and debt financing from Leonid Capital Partners. These investments have enabled the company to advance its technology and expand its manufacturing capabilities.
