摘要 |
An electrolyte-based battery cell, having a positive electrode active material layer formed adjacent to a positive electrode collector, a negative electrode active material layer formed adjacent to a negative electrode collector, a separator which has surfaces facing respective surfaces of said active material layers, an electrolyte kept within the separator, the active material layers and there between, and a conductivity measuring means for measuring an electric conductivity of the electrolyte. Also disclosed are a system, and method, for determining the state of charge of an electrolyte-based battery. |
