Criteria for quality control: The influence of electrode defects on the performance of lithium-ion batteries is reviewed. Point and line defects as well as inhomogeneities in microstructure and composition and metallic impurities are addressed.
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.
All chemical/electrochemical reactions at the interface will introduce defects and abnormal deposition on the current collectors, desquamation of active materials from current collectors, and structural deformation of batteries. Eventually, the resultant corrosion will lead to the degradation of the battery performance and lifetime.
But the results still show that electrode corrosion is the main factor to shorten the working life of batteries. In general, electrode corrosion results in the dissolution of active materials/current collectors, oxidation/passivating of current collectors, and defects of electrodes.
In this review, we first summarize the recent progress of electrode corrosion and protection in various batteries such as lithium-based batteries, lead-acid batteries, sodium/potassium/magnesium-based batteries, and aqueous zinc-based rechargeable batteries.
Although not backed up with electrochemical data it is most likely, that such strong local variations will also locally affect the electrochemical behavior of electrodes. The rate performance of battery electrodes is significantly affected by the microstructure of the composite layer.
