World Leader In Polymers
For Ev Batteries

Sulfide-based materials are the leading technology for advanced solid-state designs. However, they can be plagued by performance issues. Specifically, interfacial compatibility and resistance can play key roles in limiting performance. Polymers can provide a great enabling function for commercialization of new solid-state cell designs by improving interfacial contact and resistance control during operation. This can change the game for solid-state battery manufacturers, enabling higher levels of performance, stability, and scalability from their cells.

IONIC POLYMERS FOR SOLID STATE CELLS

Ionic Materials if focused on developing a unique class of High Dielectric Polymers (HDP) designed to enhance functional movement of ions in advanced lithium-ion cells, including Solid-State.

• High Dielectric Permittivity
  – high polarity side groups
• Low Glass Transition Temp (Tg)
  – fast segmental relaxation
• High Oxidative Stability
  – thermodynamic stability in the voltage environment of lithium-ion cells

In a race to higher energy density that provides longer range and lower cost, anode constructions are expected to pivot to silicon-dominant and lithium-metal materials. In these constructions, polymers play a critical role in simplifying cell manufacturing and mitigating material interface issues.

Ionic Materials is developing a polymer composite functional coating to enable longer cycle life and higher rate capability for lithium metal anodes.
