where t (µm) is the total thickness of the electrode-separatorcurrent collector stack (Figure ). 𝑡 = 2 × 𝑡 + 𝑡 ( ) + 𝑡 ( ) + 𝑡 ( ) + 𝑡 ( ) (14) where 𝑡 /( )/( )/ ( )/ ( ) is the thickness of separator, positive electrode, negative electrode, current collector of the positive electrode, and current collector of the negative electrode, respectively. However, if the electrodes are smaller than the maximum possible length, the length of the stack can simply be taken to be the length of the shortest electrode. Once the length and the thickness of the electrodes are determined, the volume of the electrolyte (𝑉 ) in mm , is estimated by finding the volume of the pores in the electrode stack with an additional 10 % of electrolyte to ensure that the electrode is properly soaked.
