摘要： A lithium-ion rechargeable battery module having a plurality of lithium-ion battery cells, arranged that battery cells located at an high temperature portion of the module are electrically connected in parallel with battery cells located at a low temperature portion of the module. The battery cells at the high temperature portion have a higher electric resistance at 20° C. and a better high-temperature storage characteristic at 50° C. than those of the battery cells located at the low temperature portion.

摘要： A cathode for a lithium-ion secondary battery is provided, which not only efficiently absorbs oxygen released from a solid solution based cathode active material when initial charging is applied but prevents a cathode energy density from lowering. Further, a lithium-ion secondary battery, a vehicle and a power storage system equipped with the lithium-ion secondary battery are provided. The cathode for a lithium-ion secondary battery comprises a cathode active material represented by the general formula: xLi2MO3-(1−x)LiM′O2 (where 0
