We studied phonon and scintillation properties of Li$_2$MoO$_4$ crystals for the AMoRE-II (Advance Molybdenum based Rare process Experiment - phase II), an experiment aiming at detecting neutrinoless double beta decay of $^{100}$Mo. The Li$_2$MoO$_4$ is one of promising crystal candidates among molybdate crystals containing Mo element for a simultaneous detection of heat and light signals at mK temperatures. It is advantageous to use the crystal in terms of crystal growth and internal background control. We tested Li$_2$MoO$_4$ crystals in a low-temperature detection system for high resolution phonon-scintillation measurement based on a metallic magnetic calorimeter (MMC) readout technology. We will present tests results of the Li$_2$MoO$_4$ crystals as target material and discuss a feasibility for the large scale experiment, AMoRE-II, with about 200 kg of molybdate crystals.
