Printed circuit board for connecting battery cells and battery

A board for connecting battery cells, which is formed in part from an electrically non-conductive material,

• wherein the board has on a first side and on a second side in each case at least one electrically and thermally conductive contacting section, and
• wherein each contacting section is electrically and thermally conductively connected to each other contacting section,
• wherein a core made of a thermally conductive material is arranged in the electrically non-conductive material of the board,
• wherein the at least one contacting section is arranged in each case on the sides of the electrically non-conductive material facing away from the core, and
• wherein at least one electrically and thermally conductive lead-through element extends through the core and through the electrically non-conductive material arranged on both sides of the core, and
• wherein the lead-through element is electrically insulated from the core and is electrically conductively connected to the at least one contacting section on the first side and to the at least one contacting section on the second side, such that an electrically and thermally conductive connection of the contacting sections on the first side to the contacting sections on the second side is made by the lead-through element and a heat flow can be picked up through the core and dissipated from the board.
