Materials

Exsolved perovskites can be obtained from lanthanum ferrites, such as La0.6Sr0.4Fe0.8Co0.2O3, as result of Ni doping and thermal treatments. Ni can be simply added to the perovskite by an incipient wetness method. Thermal treatments that favor the exsolution process include calcination in air (e.g., 500 deg;C) and subsequent reduction in diluted H2 at 800 deg;C. These processes allow

Lithium storage in perovskite lithium lanthanum titanate

2013/7/11. Introduction Perovskite lithium lanthanum titanate (LLTO) has long been studied as an inorganic solid electrolyte for lithium ion batteries (LIBs) due to its ionic conductivity up to 10 − 3 S cm − 1 at room temperature .However, the reaction with lithium below 1.50 V changes it from an electronic insulator to a conductor,,,, similar to the behavior of spinel Li 4 Ti 5 O 12.

Anode Material for Safe Batteries with a Long Cycle Life

The drawback is that lithium-ion batteries with lithium titanate oxide tend to have a lower energy density. The team around Professor Helmut Ehrenberg, head of the Institute for Applied Materials – Energy Storage Systems (IAM-ESS) of KIT, now investigated another highly promising anode material: lithium lanthanum titanate with a perovskite crystal structure (LLTO).

Solid lithium electrolyte

However, the composites are rich in lithium lanthanum titanate and Li4Ti5O12 dual phase boundaries due to intimate nanoscale mixing of the two phases. The apparent lithium-ion conductivity of the composite electrode gets significantly improved as compared to pristine Li4Ti5O12 due to the incorporation of lithium lanthanum titanate phase, a high lithium ionic conductor.
