Optimization for Li-ion batteries

Design complexities. Assembly efficiencies. Space constraints. Cell-PLX™ is designed to overcome them all. We give it a thin, tough structure, yielding excellent current density spread. So you get consistent performance. And super-efficient, low-loss energy transfer.

Outstanding current density spread

With patented U-Turn technology, Cell-PLX™ makes sure current density is distributed as evenly as possible and for multiple configurations.

Supports various designs

Flexibility to create designs for battery modules or new advanced cell-to-pack and cell-to-chassis configurations.

Weighs little, acts tough

Despite being especially thin at 0.17mm - 3mm, Cell-PLX™ is tough enough for large current collectors, up to 2.5m long.

A U-turn to get round hot-spots

EV batteries tend to develop hot-spots across conventional collector plates. Cell-PLX™ gets round this with patented U-Turn technology that yields uniform distribution of current density. And by reducing stress on individual battery cells, U-Turn helps batteries perform better, go further and live longer.

How it works

  1. Dielectric layer
  2. Current collector
  3. Data collection media
  4. Battery cell holder
  5. Battery cells

Applications

Like all ENNOVI components, Cell-PLX™ is suitable for numerous EV applications. It integrates seamlessly into an organized system and can be customized to your specifications.
Battery systems in cars, buses, trucks, subway systems, motorcycles, bicycles, maritime vessels.
