Abstract(E)	Improving the ion conductivity across various kinds of interfaces inside all solid state battery (ASSB)-related materials, is one of the key issues in optimizing the performance of ASSB. To support the research and development of ASSB, we have been developing various characterization methods to evaluate electrolyte structures and ionic conductivities. In this paper, we present our analysis technologies applied to optimize electrolyte structure and interface control in ASSB. Firstly, as approach of structure optimization, simulation of solid electrolyte in compressed state is introduced. By using simulation together with analysis which is difficult to realize experimentally, it provides us unique ways to reproduce the state in the battery. Secondly, as techniques of interface control, it is known that the cell performance could be greatly improved by coating the positive electrode surface with LiNbO3 (LNO). The condition of the coating distribution was investigated and the performance improvement was understood by electrochemical measurements of the cell.

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".
