After the first observation of ϕ(2170) in the process , several theoretical interpretations have been proposed to explain the nature of ϕ(2170). Aspects of ϕ(2170) are still not fully understood until now. Large J/ψ events and energy scan data samples collected by the BESIII detector provide the opportunity to perform the further study to ϕ(2170). In this presentation, and are studied to improve the measurements of mass and width of ϕ(2170). e+e− → K+K−, and K+K−K+K− are investigated to search for the new decay mode of ϕ(2170). Those studies would be useful for improving the understanding of the nature of ϕ(2170).
