Here is 4 question about battery, need 2-3 lines answers. no copy from internet, no other people work.. need it to be perfect and not more than 3 lines. Also, attached the class lecture.

1) What are the four material components of the cathode, why are they included in the cathode composition?

2) Why are electrodes calendared / compacted? What is the benefit?

3) Given a cathode weighs 7.6g, is 96% LCO, and the LCO has a specific capacity of 150 mAh/g. What is the capacity of the cathode?

4) What are “cell formation cycles” and why would one want to use them?
