This section focuses on the corrosion investigation of LIBs based on nonaqueous liquid electrolytes, partially about LMBs. Fig. 2 a-d depict an overview of potential and facultative corrosion-related reactions of nonaqueous electrolytes in comprehensively investigated lithium-based batteries [14, 29].].
The results indicate that the addition of these three chemicals into the electrolyte can greatly improve the quality of the SEI layer, promote the battery …
Porosity is frequently specified as only a value to describe the microstructure of a battery electrode. However, porosity is a key parameter for the battery electrode performance and mechanical properties such as adhesion and structural electrode integrity during charge/discharge cycling. This study illustrates the importance of using more than one …

Redox flow batteries (RFBs) are a promising technology for long-duration energy storage; but they suffer from inefficiencies in part due to the overvoltages at the electrode surface. In this work, more than 70 electrode treatments are reviewed that are previously shown ...
Carbon electrodes are one of the key components of vanadium redox flow batteries (VRFBs), and their wetting behavior, electrochemical performance, and tendency to side reactions are crucial for cell efficiency. Herein, we demonstrate three different types of electrode modifications: poly(o-toluidine) (POT), Vulcan XC 72R, and an iron-doped …

Lithium Corrosion (in Lithium–Air Batteries): Lithium anode corrosion in lithium–air batteries can result from reactions with the electrolyte or impurities in the battery environment. Corrosion products, such as lithium hydroxide (LiOH) or lithium peroxide (Li 2 O 2 ), can form on the anode, affecting battery performance and cycling stability.
In our previous research, a commonly employed surface-treated graphite felt electrode was utilized as the positive electrode for the iron‑lead single-flow battery to fully exploit the cathode''s capabilities and thereby enhance the …
