Abstract:
An electrochemical energy storage device includes a housing (102), at least one energy storage element (103) in the housing (102) and operable with an electrolyte, a cap (104) coupled to the housing (102), at least one electrolyte impregnation hole (130) formed in the cap (104), and a first terminal lug (106) attachable to the cap (104) via the electrolyte impregnation hole (130).
Abstract:
Electrochemical energy storage devices such as electric double layer capacitors include a flexible metal contact current collector establishing electrical contact with a conductive housing at numerous contact points. The flexible current collector simplifies manufacturing of the device and avoids laser welding on the conductive housing. The manufacture devices are operable with a reduced direct current resistance by virtue of the flexible current collector.
Abstract:
Moisture barrier packages for electrical components mountable to a circuit board include a cover and a base configured to provide a metal to metal joint that hermitically seals an electrical component in an enclosure defined by the cover and the base. The base may include patterned metallizations using circuit board printing techniques that facilitate connection of the electrical component to the circuit board. The base of the moisture barrier package may be configured for surface mounting of the electrical component or through-hole mounting to complete the electrical connection to the board through the base.
Abstract:
Electric double layer capacitor (EDLC) devices include sealing conductor establishing a series connection between multiple storage cells in a single package, which may be operable at higher voltages than conventional EDLC devices.
