The Structural Role of Carbon Black in Dry Electrode Processing

carbon black role in dry electrode

The conventional framing of carbon black in lithium-ion battery electrodes is electrochemical – it is an electronic conducting agent that enables the formation of the electrical wiring within an electrode. It has typically been specified by loading, surface area and subsequent powder or electrode resistivity. For wet slurry coating, this framing is broadly adequate. The … Read more

Cylindrical Cell Electrode Estimation

Cylindrical Cell Electrode Estimation: An alternative geometric approach. Here we present a simple method for estimating electrode length in a cylindrical cell. The method is equally applicable to other formats since we make an estimation of the total active electrode area. Results require knowledge of one electrode Active Material (AM) chemistry, electrode porosity and thickness … Read more
