In $e^+e^-$ collisions between 2 and 3~GeV, excited states of $\rho$, $\omega$ and $\phi$ can be produced directly. Especially the resonances around 2~GeV like $\rho(2000)$, $\rho(2150)$ and $\phi(2170)$ are not fully understood yet. Theorists describe the $\phi(2170)$ as a traditional $s\bar{s}$ state, an $s\bar{s}$ gluon hybrid, a tetraquark state, a $\Lambda\bar{\Lambda}$ bound state, or a $\phi KK$ resonance. The predicted decay widths vary strongly depending on the assumed nature of $\phi(2170)$. With energy scan data collected by the BESIII collaboration between 2.0~GeV and 3.08~GeV, the properties of $\phi(2170)$ are studied systematically in its expected decay modes, such as $e^+e^- \to K^+K^-$, $K_{S}^{0}K_{L}^{0}$, $\phi K^+K^-/K^+K^-K^+K^-$, $\phi\eta$, $\phi\eta'$, $\omega\eta$ and $K^+K^-\pi^0\pi^0$.
