Abstract(J)	本発表では，硫化物系全固体LIBの寿命試験結果と劣化メカニズムの検討について報告する．全固体LIB（SOLiD-EV 標準電池）および比較用液LIBに対し，車載用LIBの標準寿命試験法 IEC62660-1により寿命特性を評価した．また，別条件で行なったサイクル試験および保存試験の解体分析結果をもとに，全固体LIBの劣化メカニズムの検討を行った． Translation
Abstract(E)	We conducted IEC62660-1 cycle test of a sulfide-based all-solid-state battery and a conventional liquid-based lithium ion battery to evaluate and compare the durabilities of each battery. Based on the results of the cycle tests and analysis of cycle-tested electrode in the all-solid-state battery, we investigated the degradation mechanism of the sulfide-based all-solid-state battery.

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".
