摘要： A motor vehicle includes a traction battery module which has a hermetically sealed module housing in which at least one cell stack pair including a left-hand-side and a right-hand-side cell stack including, in each case, at least two battery cells is accommodated. The traction battery module is arranged in the vehicle floor and extends symmetrically in relation to the vehicle center (M) in the vehicle transverse direction (X). The traction battery module has a bottom wall in a horizontal plane. A gas space is formed in the module housing in the vehicle center (M) and between the left-hand-side cell stack and the right-hand-side cell stack with respect to the vehicle transverse direction (X). The module bottom wall has a degassing element centrally in the vehicle in the region of the gas space.

摘要： A solid-state secondary battery according to the present invention includes an electrode laminate, and an exterior body accommodating the electrode laminate. The electrode laminate has a positive electrode layer, a negative electrode layer, and a solid electrolyte layer placed between the positive electrode layer and the negative electrode layer. The positive electrode layer includes a positive electrode current collector and a positive electrode active material layer. The solid electrolyte layer has a positive electrode-facing region that faces the positive electrode active material layer, and a positive electrode-non-facing region that does not face the positive electrode layer. The positive electrode-non-facing region has a porosity of lower than 5%.

摘要： A hybrid series battery module includes a first-type battery cell including a first negative electrode plate and a second-type battery cell including a second negative electrode plate. Energy density of the first-type battery cell is less than energy density of the second-type battery cell. A first interlayer spacing of a negative electrode active material of the first negative electrode plate is greater than a second interlayer spacing of a negative electrode active material of the second negative electrode plate. In a state of charge of 0%, a ratio of the first interlayer spacing to the second interlayer spacing falls within a range of greater than or equal to 1.005 and less than or equal to 1.600.
