In a nonaqueous electrolyte battery, a negative electrode terminal is fixed to an insulating ceramic material with filler materials for brazing mainly composed of copper and insulation-sealed to an opening of a metallic exterior member with the ceramic material being provided interposed therebetween. A positive electrode terminal fixed to an insulating ceramic material with an aluminum alloy-based filler materials for brazing and insulation-sealed to the opening in the metallic exterior member.
摘要:
In a battery having a aluminum or aluminum alloy casing welded to and aluminum or aluminum alloy cover, a film of a synthetic resin and a corrosion preventing agent is formed on the outer surface of the battery raising and an electrolyte comprising hydrofluoric acid is placed in the casing. The film is capable of absorbing hydrofluoric acid. In an alternative embodiment, the exterior film may be a ceramic material capable of absorbing hydrofluoric acid.
摘要:
A metallic ring is insulatedly sealed around each of the positive electrode terminal and negative electrode terminal, previously, by the glass hermetic seal and ceramic hermetic seal in such a manner that it is sealed into the opening hole of the cover plate of a battery case. In this case, in order to prevent the corrosion of a metallic brazer which may occur in the ceramic hermetic seal and improve the workability, the ceramic material is brazed around the negative electrode terminal through a Au—Cu brazer or P—Cu brazer.

A non-aqueous electrolyte secondary battery includes a positive electrode containing a positive-electrode active material, a negative electrode containing a negative-electrode active material, and a non-aqueous electrolyte, and is characterized in that the non-aqueous electrolyte contains 1.0 wt % or less of a compound represented by formula (1) and 2.0 wt % or less of a cyclic sulfate ester represented by formula (2), based on the total weight of the non-aqueous electrolyte. By using the non-aqueous electrolyte including a specified amount of the compound represented by formula (1) and a specified amount of the cyclic sulfate ester, when the battery is used at a low temperature after being stored at a high temperature, the increase of the internal resistance is inhibited.
摘要:
A process for the production of a non-aqueous electrolyte battery which comprises a polymer layer forming step of forming a polymer layer on one side of at least one of a positive electrode, a negative electrode and a separator and an electricity-generating element preparing step of laminating or winding the positive electrode, the negative electrode and the separator to prepare an electricity-generating element. The process for the production of a non-aqueous electrolyte battery further comprises battery preparing step of receiving the electricity-generating element in a battery case, injecting an electrolyte into the battery case and then hermetically sealing the battery case to prepare a non-aqueous electrolyte battery and a heating and cooling step of heating and cooling the non-aqueous electrolyte battery while the battery case is under pressure.
摘要:
A non-aqueous electrolyte secondary battery is described, capable of inhibiting the raise of the internal resistance at a low temperature after use in a high-temperature circumstance, and having a good power performance at a low temperature. The non-aqueous electrolyte secondary battery has a non-aqueous electrolyte, and is characterized in containing a sulfate ester with a specific structure in an amount of 4.0 wt % or less relative to the total weight of the non-aqueous electrolyte.

摘要:
In a searching step, a laser beam by a laser beam projector is projected toward an object to be detected, which is previously disposed at a delivery position, while moving a holding member which is positioned apart from the object to be detected. In a delivery position data acquiring step, delivery position data is acquired by obtaining member position data provided by a member position data detecting unit when a laser beam reflected by the object to be detected is received by a laser beam receiver and calculating the delivery position data based on the member position data obtained by the member position data detecting unit.
