– Polymer Electrolyte Nanocomposite for advanced Lithium Batteries –

PENLiB

The need

As car manufacturers start to commercialise electric vehicles, the development of high performance batteries exhibiting high power and energy density becomes essential. Lithium batteries have much higher energy and power density and lower self-discharge than NiMH. However, safety of Lithium batteries is a key issue to address the electric transportation mass market. The unsafe nature of existing lithium batteries lies partly in the electrolyte. An improvement of the mechanical strength of the polymer electrolyte will avoid short-circuits but this improvement must not increase its resistivity.

The solution

The PENLiB project aims at launching a new generation of lithium-ion polymer batteries by developing new battery components.
These new components are bio sourced materials and nanocomposite reinforced polymer electrolytes. By using these components to improve and reinforce separator materials, PENLiB addresses the safety issue of lithium batteries. Besides, the global cost of the battery is decreased through the use of the nanocomposite that allows making the separator thinner, thus reducing the amount of material needed.

PENLiB also improves the battery energy density through reduction of the separator thickness, while ensuring good mechanical properties. Higher energy density battery will be achieved, leading to higher car autonomy.

In a nutshell, this project will lead to safer, cheaper and higher performance battery than current lithium-ion battery.
