A battery pack includes a plurality of cell assemblies each of which include one or more prismatic batteries. A frame has legs sized and configured to be positioned around the prismatic batteries. At least one leg includes a rear face, curved outer edge and a side face. A thermal transfer sheet is made from a sheet of a compressed mass of exfoliated graphite particles. Each thermal transfer sheet is positioned to contact the major surface of the at least one prismatic battery and is bent over the curved outer edge. At least a portion of each thermal transfer sheet is secured between a heat sink and the side face.

This disclosure details thermal management systems for thermally managing battery packs and other electric drive components of electrified vehicles. An exemplary thermal management system may include a battery cooling circuit and an e-drive cooling circuit. The e-drive cooling circuit may be fluidly connected to the battery cooling circuit by a combination of valves and coolant lines during or in anticipation of certain vehicle conditions, such as high load operating conditions, to augment cooling of electric drive components during the high load operating conditions.

A battery cooling system for a vehicle and a method are disclosed. In particular, the battery cooling system may include: a battery cooling apparatus to selectively connected to a cooling apparatus and cool a battery by coolant flowing through the battery cooling apparatus; a battery management system to measure a temperature of the battery in a periodic time interval after a vehicle is turned off; and a controller to control the battery cooling apparatus to cool the battery when the temperature of the batter is higher than a threshold temperature.

A method for at least partially removing a contamination layer (24) from an optical surface (14a) of an optical element (14) that reflects EUV radiation includes: performing an atomic layer etching process for at least partially removing the contamination layer (24) from the optical surface (14a), which, in turn, includes: exposing the contamination layer (24) to a surface-modifying reactant (44) in a surface modification step, and exposing the contamination layer (24) to a material-detaching reactant (45) in a material detachment step. The optical element (14) is typically taken, before the atomic layer etching process is performed, from an optical arrangement, in particular from an EUV lithography system, in which the optical surface (14a) of the optical element (14) is exposed to EUV radiation (6), during which the contamination layer (24) is formed.
