Maturation

Context

Electric vehicles require powerful and long-lasting batteries, but they also need to be durable, safe and fast charging. Faced with these ambitious needs, developing solid batteries (with polymer electrolytes) and lithium metal is crucial.

Technology

Polymer electrolyte combining high unipolar ionic conductivity, wide electrochemical stability window for electrode and thin membranes reinforced with Nanocellulose which overcomes the dendrite issues that usually appear with current polymer electrolyte.

Advantages

Single-ion conducting polymer electrolytes synthesized by an easy and industrializable method.
Versatile materials that can be adapted for use in electrodes (triple role: electrolyte, mechanical binder and interface) and membrane.
Ecological elaborating process.

State of progress

Laboratory proof of concept at TRL3 (protected by two patents)
Versatility and low production cost
Prototype in significant environment in autumn 2022

Applications

Lithium-ion batteries and more particularly lithium-metal batteries
Post lithium batteries
