The interface between Li6.5La3Zr1.5Ta0.5O12 and liquid electrolyte

Researchers in the Peter Bruce Group  have published in Joule a new method for protecting lithium anodes in liquid cells using solid electrolytes. 

Their research found that LLZTo is not stable in contact with the carbonate-based liquid electrolyte currently used in commercial lithium-ion batteries, but that a LLZTO/LP30 interface has a significant associated resistance.  

Furthermore, they found the resistance between the ceramic and liquid electrolyte increases to undesirable values due to the formation of a solid electrolyte interphase.
