Next-Gen Ceramic Batteries Poised to Disrupt Energy Game

Ion Storage Systems, a small Maryland-based startup born out of a university lab, is quietly reshaping the battery industry. Backed by the U.S. Department of Energy and private investors, the company has developed next-gen solid-state ceramic batteries that are now gearing up for mass production. The Wall Street Journal hints Ion could be the one to finally deliver on the long-hyped promise of safer, longer-lasting solid-state power.

Smarter Chemistry, Better Batteries

Unlike standard lithium-ion cells, which use liquid electrolytes and graphite anodes, Ion's design replaces them with solid ceramic and metallic lithium, boosting energy density by up to 50%. These batteries don't overheat or ignite—making them ideal for both defense and consumer tech. The secret sauce? A 3D porous ceramic that acts as both electrolyte and buffer, allowing flexible packaging without bulky components like springs or pressure plates.

Scaling Up for Real-World Impact

Ion has expanded its facility to 3,000 m², added new sintering furnaces, and is doubling the size of its 75-person team. Lab tests show over 1,000 charge cycles with more than 80% capacity retention. And since these cells require no compression or external pressure, they’re easier to manufacture and integrate. In March, Ion secured $20 million in ARPA-E funding and formed key partnerships with Saint-Gobain and KLA to scale up production.

If successful, Ion’s ceramic batteries could revolutionize electric vehicles, smartphones, and even aircraft—while also reducing the U.S.'s reliance on Asian battery suppliers. The future may finally be solid.
