In accordance with at least certain embodiments, the present disclosure or invention is directed to improved or novel separators such as a separator for a high energy and/or high voltage lithium ion battery which is stable up to a 4.5 volt, or preferably up to a 5.0 volt or higher charging voltage, such as a novel or improved single or multilayer or multiply microporous separator membrane.
Dopant-driven phase transitions in correlated metal oxides
Reversible phase transitions of exceptional magnitude may be induced in correlated metal oxides by altering their chemical compositions through reversible introduction of dopant ions and electronic carriers into the correlated metal oxides. One or more catalyst electrodes may be deposited onto a surface of a film of a correlated metal oxide such as a perovskite or a transition metal oxide.
