| description | The invention aims to solve a problem that a lithium ion battery in the prior art has low porosity to influence electrolyte permeation and aims to solve a problem of poor high-temperature stability ina high-energy battery scheme in the prior art. The lithium ion battery comprises a positive plate, a negative plate, a diaphragm and a non-aqueous electrolyte, wherein the non-aqueous electrolyte contains CF3CHFCF2OCH2CF3, in addition, a negative electrode active material in the negative electrode is of a layered crystal structure, the interlayer spacing is 0.32-0.36 nm, and porosity of the positive electrode sheet and the negative electrode sheet is 25% or less. The lithium ion battery provided by the invention has higher volume energy density, not only can ensure that lithium is not separated out, but also has good high-temperature and normal-temperature cycle performance, and improving energy density and stability of the battery is facilitated.
