Abstract

A successful concept demonstrator for an Additively Manufactured (AM) Li-ion battery case is presented. The novel battery case contains a conformal heat pipe with a complex internal wick structure to efficiently remove heat from the battery cell. The design, fabrication and testing of an AM unit cell battery case with an embedded heat pipe is described. The heat pipe battery case is shown to have a peak conductance that is an order of magnitude larger than a solid aluminum battery case with equivalent exterior dimensions.
