Abstract

In this paper, we report the surprisingly low electrolyte/electrode interface resistance of 8.6 ω cm² observed in thin-film batteries. This value is an order of magnitude smaller than that presented in previous reports on all-solid-state lithium batteries. The value is also smaller than that found in a liquid electrolyte-based batteries. The low interface resistance indicates that the negative space-charge layer effects at the Li₃PO_4-xN_x/LiCoO₂ interface are negligible and demonstrates that it is possible to fabricate all-solid state batteries with faster charging/discharging properties.
