Discharge and charge reactions at the positive electrode correspond to the intercalation and deintercalation of Li + ions, respectively. A large Rct during the discharging process means that the Li + intercalation resistance is greater than the deintercalation resistance. Moreover, the hysteresis increased with increasing C-rate.
The anode is one of the essential components of the battery. It is a negative electrode which is immersed in an electrolyte solution. So, when the current is allowed to pass through the battery, it oxidizes itself, and the negative charges start to lose and travel towards the positive electrode. What is the Battery Cathode?
