The PECVD technique appears to be a unique method that allows for the implementation of Li-ion batteries with particularly sophisticated architecture. A new type of 3D microbatteries with anode or cathode post-arrays has been recently developed in the Tolbert Lab at University of California (Los Angeles). However, such systems require a solid electrolyte in the form of conformal coatings that will evenly cover the high aspect ratio electrodes. Plasma deposited polyethyleneoxide-hke electrolyte films, which are electronic insulating and can be intercalated with lithium ions, have been chosen to this end. Currently, these films are intensively investigated (Dudek, 2011). 

Direct deposition of a layer of ion-conductive ceramic - LiPON, which has the formula Li cPOyNz, often used as a solid electrolyte in lithium microbatteries - and a (softer) polymer, on the surface of the lithium. In this latter case, a solution of macromonomers of poly(ethylene glycol) dimethacrylate, mixed with a radical initiator and a liquid electrolyte (which also guarantees ionic conductivity in the polymer layer), is deposited on the surface of the negative electrode. After UV activation, a layer of some ten micrometers in thickness is formed, covering the strip of metal lithium, which helps to...
