The studies on the strangeonium state $\phi(2170)$ at BESIII are presented. The cross sections of the processes $e^+e^-\to K^+K^-$, $e^+e^- \to K^+K^-\pi^0\pi^0$, $e^+e^-\to K^+K^-K^+K^-$/$\phi K^+K^-$ and $e^+e^-\to \phi\eta^\prime$ have been measured precisely in the center-of-mass energy region of $2.0-3.08$ GeV, and the parameters of $\phi(2170)$ have been extracted from the lineshapes where applicable.
