Abstract
A system includes a battery cell having a packaging and a coil disposed within the packaging. The battery cell further includes a first terminal electrically coupled to a portion the coil and protruding through an opening in the packaging, wherein the first terminal is hermetically sealed at the opening in the packaging using a compressive force.
Claims22
A system, comprising:
- a battery cell, comprising:
- a packaging having a first terminal port defined by a first cupped portion that extends outwardly from the surface of the packaging;
- a coil disposed within the packaging;
- a first terminal electrically coupled to a portion the coil and protruding through the first terminal port of the packaging;
- and
- a first press-fit ring that surrounds the first cupped portion and provides a first radially inward compressive force to the first cupped portion that hermetically seals the first terminal in the first terminal port.
3 more elements
A battery cell package, comprising:
- a first terminal port defined by a first cupped portion extending outwardly from a face of the package, wherein the first terminal port is configured to allow a first terminal to extend through the package, and wherein the first cupped portion is configured to be compressed inwardly toward the first terminal by a first press-fit ring to seal the first terminal in the first terminal port.
A method of manufacturing a battery cell, comprising:
- providing a battery package having a terminal port defined by a cupped portion extending outwardly from the battery package;
- disposing a coil assembly in the battery package, wherein the coil assembly comprises a coil coupled to a terminal;
- and
- disposing a press-fit ring around the cupped portion to inwardly compress the cupped portion and then passing the terminal through the terminal port with sufficient pushing and/or pulling force to hermetically seal the terminal in the terminal port.
