Dead lithium formed in the stripping process significantly contributes to the low efficiency and short lifespan of rechargeable lithium metal batteries. This review displays a critical review on the current research status about the stripping electrochemistry of lithium metal anode.
Therefore, the inhomogeneous coverage of SEI results in the uneven deposition and dissolution of Li electrode. 50, 189, 190 It is realized that an SEI is the key to the stripping process of Li electrode, because it serves as the conductor of Li + which is the oxidation product of Li metal during the stripping process.
Li metal in rechargeable batteries is plated and stripped from the substrate repeatedly. Several models of Li dendrite formation and growth have been proposed with the aim to understand the deposition process and mitigate or further eliminate the growth of dendrites.
During dissolution, the SEI formed at the stage of deposition has an obvious influence on the stripping process of Li anode. Steiger et al. 230 found that the thinning process of dendrites during the electrochemically stripping process started at its tip where the corresponding SEI mainly consisted of metal oxides or Li salt (Figure 13).
This finding challenges the conventional belief that high stripping rate of Li-metal battery results in the rapid decrease of Coulomb efficiency because of the formation of inactive Li. The high concentrated Li ions formed during high C-rate discharge process were immediately solvated by the adjacent solvent molecules.
The electrochemical reaction of Li metal anode during the stripping process is shown in Equation 4. As discussed above, electrochemical reaction rate (C-rate) regulates the formation of dead Li. Consequently, the understanding of interfacial reaction mechanism of Li electrode is beneficial to restrain or eliminate the formation of dead Li.

Compared to other conventional battery systems, lead-acid batteries (LABs) are often overlooked and viewed as an outdated technology with minimal technical potential. Nonetheless, research on LABs have continued from the viewpoint of new features, reliability, and fuel and cost savings, including developments of absorbent glass materials [ [1], [2], [3] ], …
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable. Desulfation is the process of reversing sulfation …

The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage …
