摘要： A battery module 100 includes a plurality of cells 10 arranged in a grid array. The cells 10 arranged in a row direction are connected together in parallel by a first connecting member 20. The cells 10 arranged in a column direction are connected together such that the cells 10 adjacent to each other in the column direction are connected together in series by a second connecting member 30. When an internal short-circuit occurs in any one of the cells 10, the first connecting member 20 connected to the cell 10 in which the internal short-circuit has occurred is melted by Joule heat generated due to a short-circuit current flowing into the cell 10 in which the internal short-circuit has occurred from the other cells 10 in which no internal short-circuit occurs via the first connecting member 20.

摘要： A non-aqueous electrolyte battery has a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode has a high-capacity positive electrode portion with a plate area per capacity of smaller than 200 cm2/Ah, and a high-power positive electrode portion with a plate area per capacity of 200 cm2/Ah or larger. The non-aqueous electrolyte battery is advantageous in providing a battery, with use of a single kind of non-aqueous electrolyte battery, which simultaneously satisfies the requirements on high-capacity characteristics capable of performing a long-term continuous discharge, and on high-power characteristics capable of performing a pulse discharge at a large current, without using a hybrid power supply unit which has multiple kinds of batteries and requires a complex control system.
