Capacity fade of Li-ion cells: comparison of DC and ENREV charging protocols
Sony 18650S Li-ion cells have been cycled using direct current and ENREV pulse charging (CC-CV) protocols. The influence of the charging protocol on the capacity fade of these batteries has been analyzed using cyclic voltammetry, galvanostatic charge-discharge and impedance spectroscopy. Batteries with different cycle numbers charged using ENREV pulse charging protocol showed superior charge transfer performance and rate capabilities and more than 90% retention of the initial capacity after 800 cycles compared with 64% retention of capacity observed for batteries charged using DC charge protocol.
