Battery case

Explosion proof valve for battery case

A semiconductor device according to an embodiment includes a first electrode; a second electrode; a gate electrode; an n-type first silicon carbide region positioned between the first electrode and the second electrode and between the gate electrode and the second electrode; a p-type second silicon carbide region positioned between the first electrode and the first silicon carbide region; a third silicon carbide region of metal containing at least one element selected from the group consisting of nickel (Ni), palladium (Pd), and platinum (Pt), positioned between the first electrode and the second silicon carbide region and spaced apart from the first silicon carbide region; and a gate insulating layer positioned between the gate electrode and the second silicon carbide region.

Semiconductor device, method for manufacturing semiconductor device, inverter circuit, driving device, vehicle, and elevator

A semiconductor device according to an embodiment includes a metal layer; an n-type first silicon carbide region; and a second silicon carbide region of metal containing at least one element selected from the group consisting of nickel (Ni), palladium (Pd), and platinum (Pt) and positioned between the metal layer and the first silicon carbide region.

A battery case provided with a safety valve () in which a breakage groove () is used, wherein in order to stabilize the operation pressure, a lid () of the battery case has formed thereon: a thin plate portion () obtained by thinning a plate part (); and a first recessed part () comprising a curved part () in which the thin plate portion () is indented inward, with respect to the case, in a curved shape. The breakage groove () for the safety valve () is formed at the bottom part () of the curved part (). A first connecting portion () and a second connecting portion () of the plate part (), which connect to the curved part () on both sides flanking the curved part (), are at positions protruding toward the outside of the case from the plate part ().
