Piersica’s core technology is a solid-state lithium battery that uses a solid polymer electrolyte (SPE) instead of liquid electrolytes to achieve an energy density target of 650 Wh/kg, enhanced safety, and rapid charging. Key innovations include a 3D lithium metal anode designed to prevent thickness changes over charge-discharge cycles with over 4,000 cycle life, a leak-free lithium-rich cathode operating up to 4.7V, and a lightweight flexible solid polymer separator compatible with high-voltage cathodes that operates at room temperature, reducing manufacturing complexity and cost.
Next-generation solid-state lithium battery cells featuring a solid polymer electrolyte, 3D lithium metal anode with >4,000 cycle life, lithium-rich cathode at 4.7V, energy density up to 650 Wh/kg, and a flexible solid polymer separator optimized for scalable manufacturing. A multi-layer prototype is under development to demonstrate a functional cell by 2025.
In 2024, Piersica received a $1 million Phase II grant from the National Science Foundation to develop and validate multi-layer battery prototypes aiming for a functional cell by 2025. In 2024, the company also secured a Shell GameChanger program grant providing seed funding and technical expertise to accelerate its commercialization efforts.
Raised nearly $2M in its initial funding round; secured $1.9M in SBIR and STTR grants from the National Science Foundation, the U.S. Army, and the U.S. Air Force; and received over $400K in non-dilutive support through the Chain Reaction Innovations program at Argonne National Laboratory.
