World Leader In Polymers
For Ev Batteries

Ionic replaces highly volatile, liquid electrolytes with advanced polymers that enable safe, high-performance, low cost and scalable architectures.


Polymer materials solve myriad battery problems in both next-generation cell designs and non-polymer solid-state systems



Catholyte, Anolyte, Separator

In a fight for 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, while ensuring a high degree of safety. Safer cells lead to higher energy density and lower cost at the pack-level.

Sulfide and Oxide-based Cell Systems

Polymers are not limited to polymer-only cell constructions. In particular, cell designs containing other advanced solid-state sulfide and oxide-based materials can be plagued by performance problems. Specifically, interfacial compatibility and resistance can play key roles in these performance limitations. Polymers can change the game, enabling higher levels of performance, stability, and scalability.

Ionic’s advanced polymers help solve the interfacial issues inherent in new battery architectures.

The EV Battery Market Needs Safer, Higher Performance Solutions

Test 1

Nail penetration of lithium-ion batteries, while a quite severe and controversial test, can demonstrate the high level of safety achieved with polymer-based solutions.

Test 2

On severe electrical abuse tests, such as overcharge, conventional, carbonate-based electrolytes can decompose leading to gassing, pressure build-up, and rapid unplanned disassembly. Polymer-based solutions mitigate these limitations.

Test 3

Severe mechanical abuse, such as crushing cells, frequently leads to hard internal short circuit events such as thermal runaway and fire. The use of polymer-based electrolytes provides enhanced mechanical abuse performance, acting as a solid buffer between electrode layers.
