| Abstract(J) | 二つのラボ試験を行い，リチウム析出の熱連鎖への影響と機械的拘束によってセル内にリチウム析出が起こることを明らかにした．熱連鎖試験では，リチウム析出があるセルへの熱連鎖はより短い時間で発生した．拘束を行ったセルは拘束を行わないセルと比較して，少ない充放電回数で容量低下し，内部にリチウム析出が発生した． Translation |
| Abstract(E) | Two laboratory-level tests were conducted to reveal the impact of lithium plating on thermal propagation and to demonstrate that mechanical constraint for a cell causes lithium plating within cells. In a thermal propagation test, thermal runaway propagated to an adjacent cell with lithium plating in a shorter period than to an adjacent cell without lithium plating. Compared to unconstrained cells, constrained cells exhibited capacity degradation after fewer charge-discharge cycles and caused lithium plating on the negative electrode. |
