### Q3. For lithium ion batteries(a) Find the theoretical value for g.pdf

• 1. Q3. For lithium ion batteries: (a) Find the theoretical value for graphite anode. (b) Find the theoretical value for silicon anode. (d) A lithium ion battery module consists of 10 cells connected in series. For each cell, assume the resistance of each electrode is 10 mohm including kinetic as well as electronic and ionic resistances. Assume that an ionic resistance of 2 mohm is associated with each positive and negative electrode pair. Assume that each tab resistance is 1 mohm. Assume each terminal resistance is 0.05 ohm. What is the resistance of the cell and what is the peak power if the open circuit voltage is taken as 3.6 V? (Use USABC definition of peak power = 2/9 x Voc2/R.) Solution the theoretical value for graphite anode in lithium ion batteries : 372 mAh/g the theoretical value for silicon anode in lithium ion batteries : 4,200 mAh/g Total resistance is :1.9 ohms peak power is: 0.87watts
