Understanding LithiumSponsored post: The area of battery technology that has attracted the most research is a class of batteries with a lithium anode. Read this to know why! Lithium has a high chemical activity, nonaqueous (organic or inorganic) electrolytes have to be used. Such electrolytes include selected solid crystalline salts. This whole new science has encouraged the commercial production of some batteries having no separator layer between the anode and the liquid cathode, an unlikely condition for success in aqueous systems.
A stable protective layer automatically forms on the lithium and serves as a separator. The protective layer becomes more porous on discharge to permit high-current operation at nearly constant voltages near 3.6 volts. Check Disclaimer on Profile and landing page.
