在电池单元操作期间，通过运行中中子反射计实时监测锂离子并入非晶硅电极中。循环伏安法实验的最新结果。这些实验使我们能够监测在循环过程中的巨大体积膨胀、固体电解质界面相（SEI）的形成和演变、不可逆容量损失的测定和耐电压效应。
Lithium ion incorporation into amorphous silicon electrodes was monitored via in-op-erando neutron reflectometry in real-time during battery cell operation. Recent results of cyclic voltammetry experiments are presented. These experiments enable us to mon-itor the enormous volume expansion, the formation and evolution of the SEI (solid elec-trolyte interphase), the determination of irreversible capacity losses and voltage hyste-resis effects during cycling.
