SCs capacitance can reach 0.260 kF/g and 0.190 kF.cm −3, respectively, by a high mass loading of 10 mg.cm −2. A high EDs of 35 Whkg −3, which is near to lead-acid accumulator, can be achieved by the combined symmetric SCs. To conclude, SCs have high PDs and rechargeable batteries have high EDs.
The electrode passivation and corrosion effects can emerge in the other rechargeable batteries and deteriorate the battery charge and discharge performance (Fig. 4) [47, 68, 70, , , , , ].
As reported, the enhanced roughness of the current collectors may improve the adhesion between electrode materials and the current collectors, which can facilitate the electrochemical performance of batteries . This implies that the electrode prepared on the surface roughened current collectors is less polarized.
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 .
Outstanding sodium storage performance is displayed by the optimized Co 1 Zn 1-S electrode, which also has a high capacity of 0.54 Ah/g at 0.1 A/g, strong rate capability at 10 A/g, and good cycle stability up to 500 cycles. Additionally, in full-cell arrangement, it exhibits promising electrochemical performance.
The chemical/mechanical spoilage of electrode materials may be ascribed to the anisotropic transformation in lattice parameters behaving as stress corrosion crack during charging/discharging. This failure results in transforming low-valence metal ions into high-valence ones.
