Battery failure analysis using EIS (electrochemical impedance spectroscopy) testing is a non-destructive method that identifies lithium-ion battery degradation modes — including S…
1. Preface A lithium-ion battery operates as a “rocking-chair” system, where lithium ions shuttle between the cathode and anode through the electrolyte (Figure 1). During charging…
Battery cell consistency is one of the difficulties that the major battery cell manufacturing companies are focusing on. In the manufacturing process of battery cells, due to fluc…
1. Introduction — Why Consistency Screening Matters In electric vehicles and energy storage systems, lithium-ion batteries are connected in series and parallel to form modules and…
Electrochemical Impedance Spectroscopy (EIS) is a non-destructive frequency-domain technique for characterizing the internal electrochemical processes of lithium-ion batteries. A …
1. Abstract High precision battery test equipment is central to credible electrochemical research and to quality-controlled production of lithium-ion cells. Precise control and me…
Cyclic voltammetry (CV) is an electrochemical technique in which a linearly changing (triangular) potential waveform is applied to a working electrode and the resulting current is…
1. Background As lithium batteries are gradually being applied in various aspects of life, the demands placed on them by people are increasing, such as longer lithium ion battery …
Have you heard of the three electrode system (3 electrode system)? Unlike the two-terminal batteries we use daily, the three electrode cell is a laboratory configuration designed …
