Machining electrical power supply device for wire electrical discharge machining apparatus

Abstract

Improved battery packaging and constructions for batteries, particularly thin, flat-profile packaged batteries are provided. The battery packaging constructions may eliminate the need for soldering by providing current collector tabs coated by electrically conductive adhesive tape such as z-axis conductive tape and may provide support for current collector tabs and a regular battery perimeter by providing supportive battery packaging and/or frame materials. Better fabrication results, particularly when the batteries are used in smart cards, RFID tags, and medical devices.
