According to one embodiment, there is provided a battery. The battery includes a metallic outer can, a wound electrode group, a positive electrode-lead, a negative electrode-lead, a positive electrode insulating cover, and a negative electrode insulating cover.

Battery with wound electrode group and positive and negative electrode insulating covers

According to one embodiment, a battery includes an electrode group, a tab, a conductive nipping member, a case, a lid and a lead. The conductive nipping member includes first and second nipping sections. The first and second nipping sections divide the tab into two bundles in which portions of the tab are laminated onto each other in a thickness direction of the electrode group. The lead includes a connecting section connected electrically to a terminal, and current collecting sections which are two sections branched from the connecting section and sandwiching the nipping member.

Battery including branched current collector sections

According to one embodiment, there is provided a battery having a plurality of current collector tabs extended from a plurality of points of a current collector of at least one electrode of a positive electrode and a negative electrode. The battery further has a lid and a lead. The lead has a current collector tab junctional part connected with the current collector tabs, a lid junctional part fixed to the lid, and a vibration absorber part linking the current collector tab junctional part to the lid junctional part.

Battery and production method thereof

According to one embodiment, there is provided a battery including a case, a lid, an electrode group, an intermediate lead, and a terminal lead. The electrode group has an end face opposed to the lid and includes current collector tabs extending from the end face. The intermediate lead contains an electrode group joint and a lead joint. The terminal lead is electrically connected to the lid and the lead joint of the intermediate lead. Each of the current collector tabs has a tip portion whose width in the direction perpendicular to the extending direction is narrow. The tip portion thereof is electrically connected to the electrode group joint.

Battery including current collector tabs

In general, according to one embodiment, there is provided a battery. This battery includes a container, a lid, a gas-relief vent, an electrode group, an intermediate lead, and a terminal lead. The gas-relief vent is provided in the lid. The intermediate lead includes a first lead-joint part, an electrode-group-joint part, and a leg part. The leg part connects the first lead-joint part and the electrode-group-joint part to each other. The first lead-joint part and the electrode-group-joint part are located on planes different from each other.
