6 FAQs about [Illustration of the corrosion principle at both ends of the battery pack]
What is battery corrosion?
Battery corrosion refers to the electrochemical process that occurs within batteries, similar to other electrochemical cells. It involves at least one anodic and one cathodic half reaction, where the anodic reactions generate electrons and the cathodic reactions consume electrons. You might find these chapters and articles relevant to this topic.
What is Cyclic Corrosion in lithium ion cells?
Understanding the cyclic corrosion processes that occur within a lithium-ion cell plays a critical role in the design of a battery pack. While the redox reactions of the lithium and electrolyte with the anode and cathode during cycling are fundamentally important to cell operation, they are not a threat to long-term reliability and safety.
What are the electrolyte corrosion reactions in a battery?
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.
How does corrosion occur in a closed electrochemical cell?
Like other electrochemical cells such as batteries, corrosion requires at least one anodic and one cathodic half reaction, where anodic reactions generate electrons and cathodic reactions consume electrons. In closed electrochemical cells, charge is consumed; there is no net generation or consumption of electrons.
How can a battery be protected from corrosion?
If batteries are not adequately protected from corrosion, they will be vulnerable to failure, including catastrophic thermal events. Corrosion risk can be greatly reduced by adhering to design principles that mitigate vapor ingress (e.g., road salt spray, humidity) into the battery pack.
Why does a pouch battery need to be corroded?
The above-mentioned electrode corrosion eventually would point to the rapid failure of a battery. Especially, galvanic corrosion with gas generation can be a serious issue at the battery level, especially for the pouch battery with low-operating pressure demand .
