The binder material—a novel aqueous borate type bio-based polymer with inherent Li + ions designed as an SEI forming binder for graphite—leads to improved diffusion of desolvated Li + ions across the solid electrolyte interface (SEI) and within the anode material and yields high conductivity, low impedance, and good stability.

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

Using alkaline metal anodes, such as lithium (Li) and sodium (Na) poses a particular challenge because the metal deposition is associated with severe electrolyte decomposition due to the high reactivities of these metals, which promotes a non-uniform nucleation and the severe growth of mossy dendritic metal.

Researchers led by a team from Griffith University in Australia have developed a multifunctional polymer binder that not only maintains the outstanding binding capabilities of sodium alginate but also enhances the mechanical integrity and lithium-ion diffusion coefficient in a LiFePO 4 (LFP) electrode during the operation of the batteries.

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

In a paper in Nature Materials , the Penn State team reports a molecular-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5 Kim, Thomas E.
