Effect of substitution (Ta, Al, Ga) on the conductivity of Li7La3Zr2O12
TL;DR: In this paper, the authors show that cubic stabilizing substitutions outside of the Li-ion sub-lattice are preferable to obtain faster Li ion conductivity, and they also suggest that cubic stabilization substitutions are preferable for obtaining faster Liion conductivity.
Journal ArticleDOI
Understanding Solid Electrolyte Interface Film Formation on Graphite Electrodes
TL;DR: In this paper, the formation process of solid electrolyte interface (SEI) film on graphite electrode during initial cycles was studied using ac impedance, and it was shown that the SEI formation takes place through two major stages.
Journal ArticleDOI
An Attempt to Formulate Nonflammable Lithium Ion Electrolytes with Alkyl Phosphates and Phosphazenes
TL;DR: Using alkyl phosphates and a cyclophosphazene as cosolvents, the possibility of formulating a non-flammable electrolyte for lithium-ion batteries was explored in this paper.
Journal ArticleDOI
Tetragonal vs. cubic phase stability in Al – free Ta doped Li7La3Zr2O12 (LLZO)
Travis Thompson,Jeff Wolfenstine,Jan L. Allen,Michelle Johannes,Ashfia Huq,Isabel N. David,Jeff Sakamoto +6 more
TL;DR: In this article, Al-free subcritically doped (Li6.5La3Zr1.5Ta0.25O12) and critically doped compositions are investigated.
Journal ArticleDOI
Electrical conductivity and charge compensation in Ta doped Li4Ti5O12
Jeff Wolfenstine,Jan L. Allen +1 more
TL;DR: Ta doping in Li4Ti5O12 (Li4Ti4.95Ta0.05O12) as function of different heat-treat atmospheres (oxidizing/reducing) was investigated as mentioned in this paper.
