Arizona Patent of the Month – June 2024

Sion Power Corporation, a privately owned company that began as a spin-off from Brookhaven National Laboratory in 1989 as Moltech, has unveiled an innovative battery design that promises to revolutionize energy storage and performance. This new battery features a robust housing made from over 50 laminated layers of unidirectional carbon fiber. These layers exhibit exceptional tensile and flexural moduli, each exceeding 120 GPa, providing both strength and flexibility.

The housing is designed to apply an anisotropic force during the battery’s charge and discharge cycles, ensuring optimal pressure on the electrochemical cells. This pressure, at least 10 kgf/cm², enhances the battery’s performance by maintaining consistent contact and reducing expansion and contraction during operation. This meticulous engineering results in a battery with a specific energy greater than 250 Wh/kg and a volumetric density exceeding 230 Wh/L, making it incredibly efficient.

The housing’s compact design, with volumes as low as 6750 cm³, allows for high energy density without adding significant bulk. This feature is crucial for applications requiring lightweight and compact power sources. The carbon fiber layers not only provide mechanical strength but also contribute to thermal management, ensuring the battery remains cool and operational even under high loads.

Inside the housing, the battery includes thermally insulating compressible solid article portions that protect and separate the electrochemical cells. These components have a low compression set, maintaining their shape and effectiveness even under constant force. This design innovation minimizes thermal conductivity, preserving the battery’s integrity and prolonging its lifespan.

Sion Power Corporation’s new battery design exemplifies cutting-edge research and development, pushing the boundaries of what is possible in energy storage technology. By integrating advanced materials and precise engineering, this invention sets a new standard for high-performance, reliable batteries that can meet the growing demands of various industries.
