Hello,
In numerous research papers, they mention N/P ratios, measured in mA/cm2 units. I am curious about the specific area considered in a coin cell. When envisioning the cathode as a cylinder, do you include the entire surface area, or only the cross-sectional area (a circle)? For instance, if we have an NMC cell with a Li Anode, how would we calculate the N/P ratio? Also, what essential information can be derived from this value?
Thank you in advance.
Dear Joao, when you use half cell which means Li metal is a opposite electrodes, you dont need to use N/P ratio, this calculation is for full cells and during the design of the full cell, you should adjust optimum number of Li-ion and due to this reason you use N/P ratio, you can find a lot of information on the web for more details
