26 Apr 2012TL;DR: In this article, a gegenuberliegenden Oberflachen (121A, 121B) vorspringen und sich parallel zueinander entlang derselben erstrecken.
Abstract: Ein Batteriepaket weist Batteriemodule (130), die jeweils eine Batteriezelle (110) und einen Batteriemantel (120), der die Batteriezelle (110) darin haust, haben, auf. Die Batteriemodule (130) sind in einer Stapelrichtung gestapelt, sodass ein Kuhlkanal (140) zum Ermoglichen, dass ein Kuhlmedium fliest, zwischen gegenuberliegenden Oberflachen (121A, 121B) von benachbarten Batteriemanteln (120) definiert ist. Eine der gegenuberliegenden Oberflachen (121A, 121B) hat erste Rippen (123A), die zu der anderen der gegenuberliegenden Oberflachen (121A, 121B) vorspringen und sich parallel zueinander entlang derselben erstrecken. Die andere der gegenuberliegenden Oberflachen (121A, 121B) hat zweite Rippen (123B), die zu der einen der gegenuberliegenden Oberflachen (121A, 121B) vorspringen und sich parallel zueinander entlang der anderen erstrecken. In dem Kuhlkanal (140) schneiden die ersten Rippen (123A) und die zweiten Rippen (123B) einander, und Endabschnitte der ersten Rippen (123A) und Endabschnitte der zweiten Rippen (123B) sind in der Stapelrichtung in einer Beruhrung miteinander.

TL;DR: In this article, the authors proposed to reduce the temperature difference occurring in a battery cell when compared with prior art, while limiting the physical constitution, by making the battery cell thinner than conventional.
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature difference occurring in a battery cell when compared with prior art, while limiting the physical constitutionSOLUTION: In the heat transfer structure of a battery cell 11 having a battery cell 11, a plate 13 capable of heat transfer to the battery cell 11, and a heat exchange section 28 performing heat exchange by coming into direct or indirect surface contact with at least one surface of the plate 13, a thermal diffusion sheet 14 coming into direct or indirect surface contact with one or both of the battery cell 11 and the plate 13 is provided in lamination therewith Since the thermal diffusion sheet 14 is thin, the overall thickness can be made thinner than conventional, and since heat is transferred while being diffused, temperature of the battery cell 11 can be made uniform Consequently, the temperature difference occurring in the battery cell 11 can be made smaller than conventional, while limiting the physical constitution

Abstract: PROBLEM TO BE SOLVED: To enhance the battery performance when compared with prior art, by limiting temperature difference among a plurality of battery cells.SOLUTION: In the heat transfer structure of a battery pack performing heat transfer of the battery pack having a plurality of battery sub-modules 10 arranged while superimposed in a direction intersecting the plane direction, for the battery sub-modules 10 where a plurality of battery cells 11 are arranged side by side in the plane direction, a plate 13 capable of heat transfer by coming into surface contact with a surface corresponding to the plane direction for the plurality of battery cells 11 is provided. Since heat is transferred via the plate 13, the temperature difference in one battery cell 11 or the temperature difference among the plurality of battery cells 11 is limited. Consequently, battery performance can be enhanced when compared with prior art.

TL;DR: In this paper, it was found that there is a problem with the action of residual ion included in the polyarylene sulfide-based resin and the problem can be solved by reducing the residual ion concentration.
Abstract: PROBLEM TO BE SOLVED: To provide a sealed battery case capable of sealing a battery stably for a long time.SOLUTION: A sealed battery case has a sealing part for sealing a main body part by thermal fusion so as to store a power generation element inside, and the sealing part is made of a polyarylene sulfide-based resin with a residual ion concentration of 110 ppm or less by quantity reference. In the prior art, corrosion occurs at a juncture between the polyarylene sulfide-based resin and a metal component. Through the investigation of the cause of the corrosion, it is found that there is a problem with the action of residual ion included in the polyarylene sulfide-based resin and the problem can be solved by reducing the residual ion concentration. As a manufacturing method for the polyarylene sulfide-based resin commercially distributed, a polymerization method using sodium salt has been adopted as a practical method, and residual ion such as sodium ion is included at hundreds of ppm or more although the sodium ion is removed to some degree.
