There is a critical need to develop new energy systems that
operate both efficiently and economically on renewable sources.  In order to utilize
these systems effectively, it is necessary to develop batteries that store the
produced energy that are stable in extreme conditions and have enhanced high-voltage
and high-capacity capabilities.  One proposed alternative to the current
Li-ion based batteries is an all-ceramic
battery with higher energy density and cyclability.
One potential electrolyte for use in these types of batteries is the
Li0.35La0.55TiO3 (LLT) composition. In this work, the compatibility of LLT with electrodes such as LiCoO2,
LiMn2O4, and Li 4Mn5O12 was investigated.  The single problem yet to be successfully addressed is
the poor contact between the electrolyte and electrode which leads to high
charge transfer resistance and lower battery performance.  This work will focus on
 developing and testing novel electrode architectures in order to improve the
electrolyte–electrode interface and therefore improve battery performance.
