多壁碳纳米管(MWCNTs)在电化学插锂过程中的剥离与其内径和壁厚有关。芯径为10 nm、壁厚为5 nm的样品在以碳酸亚乙酯(EC)为基础的电解液中无剥落现象，在以碳酸亚丙酯(PC)为基质的电解液中也无剥落现象。多壁碳纳米管插入锂时石墨烯层的剥离不仅取决于溶剂化的Li+离子的大小，还取决于壁上石墨烯层之间的溶剂化Li+离子的浓度。
Exfoliation from multiwalled carbon nanotubes (MWCNTs) during electrochemical insertion of lithium is shown to depend on the inner diameter of the tubes and the wall thickness. Those with core diameters of 10nm and walls 5nm thick showed no incorporation of solvated Li+ions into the core and exfoliation as a result of solvated Li+ions entering the walls; those with core diameters of 40nm with walls 30nm thick showed no exfoliation in an electrolyte based on ethylene carbonate (EC) and little exfoliation even in electrolytes based on propylene carbonate (PC). Exfoliation of graphene layers from a MWCNT on lithium insertion depends not only on the size of the solvated Li+ions, but also on the concentration of the solvated Li+ions between the graphene layers in the walls.
