Abstract
An interlayer produced from an electrolyte additive carrying with a large amount of metal nitrates by subjecting a polymer solution, wherein metal nitrates are dissolved, to an electrospinning method, and also further includes the interlayer in a lithium metal battery using a carbonate electrolyte to thereby provide a lithium metal battery having significantly superior electrochemical performance and stability compared to lithium metal batteries using conventional commercially available carbonate electrolytes.
Claims11
An electrolyte additive comprising:
- a polymer nanofiber structure;
- and
- a metal nitrate carried on the polymer nanofiber structure,
- wherein the metal nitrate comprises lithium nitrate or rubidium nitrate.
A manufacturing method of a lithium metal battery, comprising the steps of:
- preparing an electrolyte additive comprising a mixture of a polymer and a metal nitrate;
- preparing an interlayer from an electrolyte and the electrolyte additive;
- and
- disposing a lithium metal anode at a lower part of the interlayer and sequentially disposing a separator and a cathode on an upper part of the interlayer.
