摘要： A nickel-based active material precursor for a lithium secondary battery includes: a secondary particle including a plurality of particulate structures, wherein each particulate structure includes a porous core portion and a shell portion, the shell portion including primary particles radially arranged on the porous core portion; and the secondary particle has a plurality of radial centers. When the nickel-based active material precursor is used, a nickel-based positive active material having a short lithium ion diffusion distance, in which intercalation and deintercalation of lithium are facilitated, may be obtained. A lithium secondary battery manufactured using the positive active material may exhibit enhanced lithium availability, and may exhibit enhanced capacity and lifespan due to suppression of crack formation in the active material during charging and discharging.

摘要： A battery module includes: a plurality of aligned battery cells having differently-oriented surfaces; a cell supervision circuit (CSC) configured to receive signals corresponding to the voltage and/or temperature of at least one of the battery cells; and a flexible interconnector comprising a strip-shaped flexible printed circuit (FPC). The FPC includes a first insulating main surface, a second insulating main surface opposite the first insulating main surface, and a plurality of thermally and/or electrically conducting lines between the first insulating main surface and the second insulating main surface. Each of the conducting lines has a contact portion exposed by a contact aperture in the first insulating main surface and/or in the second insulating main surface and a connecting portion for connection to the CSC, and the flexible interconnector wraps around the battery cells such that the contact portions contact the differently-oriented surfaces of the battery cells.
