PRISMATIC INVERTED-U BATTERY STACK GEOMETRY
This abstract first appeared for US patent application 20240429495 titled 'PRISMATIC INVERTED-U BATTERY STACK GEOMETRY
Original Abstract Submitted
a prismatic battery includes a prismatic battery can having an upper region, a vertical z-direction along a height of the prismatic battery can, and a horizontal y-direction along a width of the prismatic battery can. a plurality of stacked battery layers is disposed inside of the prismatic battery can. the stacked battery layers have an in-plane direction and a transverse direction that is perpendicular to the in-plane direction. the stacked battery layers have an orthotropic thermal conductivity that has a high, in-plane thermal conductivity in the in-plane direction and has a low, transverse thermal conductivity in the transverse direction. the stacked battery layers are folded inside of the prismatic battery can in an inverted-u geometric configuration. the inverted-u geometry is configured to provide a longer thermal delay time and a reduced peak temperature in response to a thermal runaway event occurring in an adjacent battery can.
