摘要 |
Lithium micro-battery comprises a substrate (2) on which is arranged a stack including successively a cathode (4), an electrolyte (5) containing lithium and an anode (6) of lithium metal and a protective envelope incorporating at least two distinct superposed layers (7, 8) covering the stack in order to protect it against external contamination. The first layer, deposited over the whole of the anode, comprises at least one material chemically inert with respect to lithium, chosen from amorphous hydrogenated silicon carbide, amorphous hydrogenated silicon oxycarbide, amorphous hydrogenated carbon, amorphous fluoridated carbon or amorphous hydrogenated silicon. The second layer comprises a material chosen from amorphous hydrogenated silicon carbonitride, amorphous hydrogenated silicon nitride or amorphous fluoridated carbon. An independent claim is also included for the fabrication of this lithium micro-battery. |
