NOVELTY - Lithium-ion battery comprises e.g. at least a first electrode comprising at least a first metal support and a first active material, with which a first metallic support is coated, where a first barrier layer is formed between the first metal support and the first active material, a second electrode, and a separator for separating the first electrode and the second electrode from each other, and with which the first active material and the second active material is coated, where a layer of a third material comprising graphene, extends at least partially into at least one of the barrier layers.    USE - The lithium-ion battery is useful for supplying energy to mobile information devices, tools, electrically powered automobiles, for automobiles with hybrid drive and/or for stationary energy storage, and the material comprising graphene is useful for coating at least an arrester for a positive electrode of a lithium ion battery, an arrester for a negative electrode of a lithium ion battery, a positive electrode of a lithium ion battery, a negative electrode of a lithium ion battery, or a lithium ion battery separator (all claimed).    ADVANTAGE - The lithium-ion battery makes use of: a material with graphene, which improves shelf-life of the battery, and which ensures reduced internal resistance, and thus it improves electrical performance of the battery; and a separator, which improves dissociation, and thus it provides better ionic conductivity in high current range.    DETAILED DESCRIPTION - Lithium-ion battery comprises at least (i) a first electrode comprising at least a first metal support and a first active material, for intercalating metallic lithium or lithium ions or for conducting lithium ions, and with which a first metallic support is coated, where a first barrier layer is formed between the first metal support and the first active material, (ii) a second electrode comprising at least a second metal support and a second active material, for intercalating metallic lithium or lithium ions or for conducting lithium ions, and with which a second metallic support is coated, where a second barrier layer is formed between the second metal support and the second active material, and (iii) a separator for separating the first electrode and the second electrode from each other, and with which the first active material and the second active material is coated, where a third barrier layer is formed between the first active material and separator, and a fourth barrier layer is formed between the second active material and separator, where a layer of a third material comprising graphene, extends at least partially into at least one of the barrier layers.
