Ultra-Thin Glass Separator Doubles Performance Potential
ATLANTA, GA (Nov 16, 2023) – In a groundbreaking advancement in battery technology, Johnson Energy Storage (JES) today unveiled its latest solid-state battery featuring an unprecedented 5-micron glass separator. This technological leap, achieved through a proprietary low-cost manufacturing process, is a significant step towards more reliable and efficient energy storage solutions.
The new solid-state batteries, characterized by their thin glass separator, exhibit reduced cell resistance and enhanced performance, particularly at lower temperatures—a notable improvement over conventional lithium-ion batteries. This advancement is a direct result of the company’s innovative glass infiltration process, which has been refined to produce remarkable results.
Unlike traditional batteries that rely on highly flammable liquid electrolytes, Johnson Energy Storage’s batteries are entirely solid-state, using the unique ion-conducting properties of glass. This structure not only eliminates the risk of flammability but also incorporates lithium metal plating at the anode, doubling the potential energy density compared to current market offerings.
“Creating a solid electrolyte that is in direct contact with the active cathode was our first challenge. Since achieving this, we have advanced our fabrication process to reliably create an ultra-thin separator in the same process. This is a critical breakthrough in enabling solid state batteries to compete in the marketplace.”
– William (Bill) Rauch, Ph.D, JES VP, Research
The company’s pioneering approach significantly undercuts the thickness of traditional polymer-based separators, which are typically over 5-times as thick and saturated with liquid electrolyte. By employing a lithium metal anode and eliminating the need for graphite or silicon, Johnson Energy Storage’s batteries not only cut down on volume, weight, and cost but also promise unparalleled safety and energy density.
Johnson Energy Storage is rapidly advancing towards commercializing this cutting-edge solid-state battery technology. With its glass-based electrolyte and cost-effective production methods, the company is poised to redefine energy storage standards and bring a superior battery solution to the market.
