Provided by the Springer Nature SharedIt content-sharing initiative Reactive negative electrodes like lithium (Li) suffer serious chemical and electrochemical corrosion by electrolytes during battery storage and operation, resulting in rapidly deteriorated cyclability and short lifespans of batteries.
All in all, electrode corrosion urgently needs to be taken into great consideration in battery degradation. The modification of electrolyte components and electrode interface are effective methods to improve the corrosion resistance for electrodes and the lifetime performances.
On the cathode side, the corrosion of the Al current collector and the generation of the cathode electrolyte interface (CEI) are electrolyte corrosion reactions in the battery. On the anode side, the solid electrolyte interface (SEI) and galvanic couple between the anode materials and the Cu current collector are shown in Fig. 2 d-e.
In addition, the metal anode would suffer self/galvanic corrosion failure when it is contacted with the electrolytes. It has been indicated that galvanic corrosion in aqueous electrolytes is more severe compared to organic electrolytes. The above-mentioned electrode corrosion eventually would point to the rapid failure of a battery.
The main purpose of electrolyte research is to optimize battery performance, and electrode corrosion is only one assessing aspect of the investigation. Interface modification (especially from carbon derivatives) may be the most promising strategy to reinforce the protection of electrodes.
In general, electrode corrosion results in the dissolution of active materials/current collectors, oxidation/passivating of current collectors, and defects of electrodes. Gradually, the adherence between electrode materials and current collectors is diminished.
