Abstract(J)	リチウムイオン電池は，電池内部で導電性異物による短絡が発生した際の安全性を確認することが重要である．現在の強制内部短絡試験方法は，電池を解体した上で微小金属片を電極内部へ組み込む必要があるため，専門知識と技術が必要であった．そこで，電池の解体が不要な簡便な内部短絡試験手法を開発した． Translation
Abstract(E)	For lithium-ion cells, it is very important to confirm the safety in the event of an internal short-circuit caused by the contamination of conductive particle inside the cell. In the current forced internal short-circuit test method, it needs to disassemble the cell and insert a minute metal particle inside the electrode. This test can not be carried out without expertise and skill. Therefore, we have developed a simple method that does not require cell disassembly.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
