▎ 摘　　要

NOVELTY - The electrode sheet has a current collector (101) and an isolating layer (103). The current collector is comprised of a first surface and a second surface. The isolation layer is arranged on one of the first surface or second surface, and the component of the isolation layer is comprised of hexagonal boron nitride. The flexible material is comprised of graphene oxide, two-dimensional material, polyethylene oxide, resin polyester fiber paper, nonwoven fabric and nano-cellulose. The adhesive is comprised of polyvinyl alcohol, acrylonitrile, acrylic acid, styrene-butadiene rubber, carboxymethyl cellulose, polyvinylidene fluoride, polyvinyl pyrrolidone and polyimide. The lithium salt is comprised of lithium perchlorate, lithium chloride, lithium hexafluoroarsenate, lithium hexafluorophosphate, lithium tetrafluoroborate and lithium bis fluorosulfonyl imide. USE - Electrode sheet for battery (claimed) such as lithium ion battery, used in consumer electronics and new energy automobile. ADVANTAGE - The electrode sheet with different polarities in the preparation process of the battery can be directly laminated or wound to form an electric core. The sheet simplifies the battery structure, reduces the process of setting the diaphragm, avoids the diodes dislocation, falling and so on caused by short circuit in the battery, so as to improve the safety of battery. Because the battery cancels the setting of the dongs, interval the distance between the electrode sheet, increasing the ratio of the active material in the sheet under the condition of not changing the thickness of battery, improving the energy density of battery and improving the battery safety. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a battery; and a battery preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode sheet for battery. 101Current collector 102Active layer 103Isolating layer
