▎ 摘　　要

NOVELTY - The material comprises branched or linear unsaturated aliphatic hydrocarbons comprising 10-50C and carbon-carbon double or triple bonds for use in an electrochemical cell. A boiling point of unsaturated hydrocarbon is above 150 degree Celsius. The unsaturated hydrocarbon is selected from decene, dodecene, undecene tridecene, tetradecene, pentade cene, hexadecane, heptadecen, octadecne, 1,9-decadiene, docosene, hexacosene, eicosene, tetracosene, squalene, farnesene, b-carotene, pinenes, dicyclopentadiene, camphene, a-phellandrene, b-phellandrene, terpinenes, b-myrcene, limonene, 2-carene, sabinene, a-cedrene, copaene, b-cedrene, decyne, dodecyne, octadecyne, hexadecyne , tridecyne, tetradecyne and docosyne. USE - Potting/coated material e.g. silicon monoxide, lithium tantalate, lithium aluminate, zirconium dioxide, lithium nbiobium monoxide, electronically conductive material such as carbon black, acetylene black, graphite, graphene, carbon fiber, carbon nanofiber and carbon nanotube, for use in an electrode material e.g. positive electrode material and negative electrode material, an electrolyte e.g. liquid electrolyte such as salt in solvent, and solid polymer electrolyte such as salt in solvating polymer, polymer-ceramic hybrid solid electrolyte, inorganic solid electrolyte and ceramic type inorganic solid electrolyte, a current collector and an electrochemical cell or electrochemical battery e.g. solid-state electrochemical cell such as all-solid battery, lithium battery, lithium-ion battery, sodium battery, sodium-ion battery, magnesium battery and magnesium-ion battery (all claimed). ADVANTAGE - The material has high ionic conductivity at room temperature, and provides the electrochemical cell having excellent electrochemical stability, high transport number and low dispersion problems. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for manufacturing coated particles; and an electrode material; and an electrochemical cell. DESCRIPTION OF DRAWING(S) - The drawing shows a photo of images obtained by a scanning electron microscopy.
