使用中子射线照相术对 ICP-340848 型商用棱柱形锂离子电池（Renata AG，瑞士）进行了研究。测量结果表明，电池中最初存在的过量电解质在第一次电池充电和固体电解质界面形成后被消耗。在第一次充电/放电循环期间，锂离子电池的原位中子射线照相显示，由于电极组件的体积变化以及第一次充电循环中气体的逸出，过量电解质发生了位移。 (C) 2001 Elsevier Science B.V. 保留所有权利。
Commercial, prismatic lithium-ion cells, type ICP-340848 (Renata AG, Switzerland), were investigated using neutron radiography. The measurements revealed that an excess of electrolyte initially present in the cell was consumed after first cell charging and solid electrolyte interphase formation. In situ neutron radiography of the lithium-ion cells during the first charge/discharge cycles showed a displacement of such excess electrolyte owing to volume changes of the electrode assembly as well as to an evolution of gases in the first charging cycle.
