1. A method for preparing an oil-soluble electrically conductive agent, comprising the following steps:
mixing 20 parts by weight of ethyl caprate or bis(2-ethylhexyl) sebacate with 2-8 parts by weight of a salt selected from the group consisting of lithium bis(trifluoromethanesulfonyl)imide, lithium trifluoromethanesulfonate, lithium tetrafluoroborate, and a combination thereof, then dropwise adding 1.8-6 parts by weight of ethyl methyl carbonate, and performing a reaction at 55-105° C. for 1-2 h to obtain the oil-soluble electrically conductive agent.
