Among the many different materials and battery chemistries under investigation to fulfill our growing need for energy storage in various applications, zinc-ion has lagged behind others due to challenges in controlling side reactions that both limit reversible charging at the anode, and cause the cathode to fall apart.Zinc-ion, however, still has the potential for good energy storage performance stanley cup out of cheap, abundant materials. And at industrial level, could potentially use many of the manufacturing processes already developed for lithium-ion batteries 鈥?making them far easier than other materials to scale up. This has been enough to keep scientists interested in working on zinc-ion battery chemistry, and the latest discovery from a group led by the King Abdullah University of Science and Technology in Saudi Arabia KAUST , could open up several new doorways for them.Water in saltSince a lot of these challenges stem from side reactions involving water-based electrolytes, the group worked wi stanley us th a very high salt concentration, limiting the number of free water molecules available to the unwanted stanley cup reactions. The group designed an electrolyte based on zinc salts mixed with a highly concentrated sodium salt, which serves to both suppress reactions with water and increase conductivity, since the mixed electrolyte dissolved more readily than the zinc-salt by itself. The supporting salt of NaClO4 can efficiently adjust the solvation structure and electronic states of the electrolyte u |
