View moreThe research team knew that aluminum would have energy, cost, and manufacturing benefits when used as a material in the battery’s anode—the negatively charged side of the battery that stores lithium to create energy—but pure aluminum foils were failing rapidly when tested in batteries. The team decided to take a different approach.
“Our new aluminum foil anode demonstrated markedly improved performance and stability when implemented in solid-state batteries, as opposed to conventional lithium-ion batteries.” The team observed that the aluminum anode could store more lithium than conventional anode materials, and therefore more energy.
foils have shown poor performance in batteries with non-aqueous electrolyte solutions under practically relevant conditions17–20. Degra-dation of aluminum electrodes is thought to occur due to porosity formation and SEI growth in liquid electrolytes21–24, diffusional trap-ping of lithium25–28, and mechanical fracture14,29–33.
Cathodes in solid state batteries often utilize lithium cobalt oxide (LCO), lithium iron phosphate (LFP), or nickel manganese cobalt (NMC) compounds. Each material presents unique benefits. For example, LCO provides high energy density, while LFP offers excellent safety and stability.
This perspective discusses key advantages of alloy anode materials for solid-state batteries, including the avoidance of the short circuiting observed with lithium metal and the chemo-mechanical stabilization of the solid-electrolyte interphase.
