Insight into the Gassing Problem of Li-ion Battery
Since "4δLi + + δO 2 " in the product side of Eq. 6 is equivalent to "2δLi 2 O – 4δe −," the net result of the O 2 evolution is a loss of Li 2 O. In accompany with the O 2 evolution, the released Li + ions are incorporated into the SEI of the cathode, which results in the growth of the cathode SEI and contributes to the irreversible overcharging capacity.
