Next Generation Battery Challenges

Over the past several decades, battery technology has been primarily driven by the need for longer operating time and cycle life in portable computers and mobile electronics. Many are familiar from consumer electronic purchases with improvements brought about by liquid-based battery chemistries such as NiCd (Nickel Cadmium), NiMH (Nickel Metal Hydride) and Li-ion (Lithium Ion).

IntroductionEmerging electric vehicle and grid storage applications stress batteries well beyond mobile requirements. Liquid battery chemistries (primarily Li-ion variants) have been incrementally adapted for vehicle and grid applications, but still fall short in delivering the needed combination of energy storage capacity, safety, battery size and weight, reliability and cost. Emerging high energy battery applications are clearly primed for a technology breakthrough that addresses current generation battery limitations.

Seeo DryLyte™ Technology

Seeo has taken a fundamentally different approach to addressing high energy battery challenges. Instead of a traditional liquid electrolyte, Seeo invented DryLyte™, a transformational solid-state battery technology based on a nanostructured solid polymer electrolyte.

In contrast to existing liquid and gel-electrolyte battery technologies, Seeo’s electrolyte is entirely solid-state with no flammable or volatile components. Solid battery materials are inherently safer than liquids, which are more vulnerable to fires under crush or overvoltage conditions. A DryLyte solid-state battery can access approximately twice the energy at the same weight compared to competitive approaches. Higher energy density enables vehicles with increased range and/or payload as well as a more environmentally friendly battery that uses fewer raw materials. DryLyte batteries also exhibit high reliability, with extended calendar and cycle life and no sudden failure modes that may occur in liquid-based batteries.
