Our Scientific Breakthrough
Through Ionic Materials’ invention of a novel solid polymer electrolyte material that conducts ions at room temperature, we are on the verge of revolutionizing battery technology. A truly solid state battery is now possible. Significant improvements in battery safety, performance and cost are achievable with ionic conductivities that exceed those of traditional liquid systems over a wide range of temperatures.
Benefits of this solution include:
- Inherent Safety: Eliminates safety issues with liquid electrolytes
- Higher Performance: Enables higher energy anodes and cathodes
- Lower Cost: Reduces battery cost through less expensive chemistries and novel manufacturing
Replacing flammable liquid electrolytes with Ionic’s non-flammable solid polymer drastically improves battery safety and robustness, as Ionic has demonstrated in a number of safety tests. Numerous prospective customers and partners in a variety of different industries/applications have emphasized the value of improved battery safety, particularly given the recent spate of battery-related safety issues. Electric vehicle companies have indicated that improved cell-level safety may lead to performance improvements and cost reductions at the pack-level, particularly if they allow the elimination or simplification of cooling and battery management systems.
Ionic has demonstrated that its polymer electrolyte is compatible with chemistries that have much higher theoretical performance limits than the active materials used in current state-of-the-art batteries. Higher energy density chemistries can now be developed and brought to market effectively. Ionic Materials is a true “platform technology” enabling the use of a wide range of electrode chemistries, including lithium metal anodes, sulfur cathodes, and more, resulting in much higher energy density and performance.
Our polymer is compatible with a number of next generation chemistries that have the potential to significantly reduce battery costs per kWh (either because they use lower cost materials, because they enable much higher energy densities, or both). In addition, use of Ionic’s polymer as a battery electrolyte potentially enables the production of batteries using extrusion and other plastic processing techniques that are simpler and lower cost than the methods used to manufacture liquid electrolyte batteries.
