Olefin separator free Li-ion battery

A method of forming a battery, comprising:

• depositing a ceramic separator layer on a surface of a negative electrode structure, comprising:
• exposing a metallic material to be deposited on the surface of the negative electrode structure positioned in a processing region to an evaporation process to form an evaporated metallic material;
• flowing a reactive gas into the processing region, comprising:
• exposing oxygen to water vapor to form moist oxygen;
• and
• introducing the moist oxygen into the processing region;
• and
• reacting the reactive gas and the evaporated metallic material to deposit the ceramic separator layer on the surface of the negative electrode structure;
• and
• joining the negative electrode structure with a positive electrode structure with the ceramic separator layer therebetween.
