Energy storage insulation cushion customization

Do cushioning materials increase battery energy density?

However, cushioning materials take up precious space that could otherwise be devoted to increasing battery energy density. This paper explores how to strike this balance in pouch cell battery designs by customizing the compression range of the cushioning material.

Why should EV OEMs use 3M cushioning material?

An advanced cushioning material from 3M can be tailored to precise design needs to provide a wide compression range at relatively low thicknesses. Consistent pressure can be achieved even with limited between-cell space, helping EV OEMs protect cells, ensure reliable performance and extend EV battery lifespan.

Why do EV batteries need cushioning materials?

Efective, space-eficient cushioning materials are needed to help protect cells during expansion and help increase battery lifespan. All lithium-ion EV battery cell types — cylindrical, prismatic and pouch — experience volumetric expansion. As cells charge and discharge, they expand and contract.

What makes a good battery cushion?

battery cushions and compression pads used within an electrical vehicle’s battery pack must be firm enough to hold components in place and compressible enough to withstand recurrent dimensional changes over the battery’s lifetime. A precision die-cut part is only as good as the material from which it’s made.

Why do EV batteries need custom elastomeric materials?

EV batteries present numerous challenges for design engineers seeking ways to extend range while achieving safety targets and minimizing complexity, volume, and weight. Rogers partners with OEMs and Tiers to improve and optimize battery performance by rapidly developing custom elastomeric material solutions unique and critical to each EV program.

What is a effective between-cell cushioning material?

An efective between-cell cushioning material should provide relatively consistent CFD over a broad range of displacements.
