Li2MoO3 has a wide range of lithium deintercalation (lithiation / delithiation) reaction potentials, R-3m space group, unit cell parameters are a = 0.2874nm, c = 1.5038nm, Mo3 clusters exist in the single crystal, and the crystal structure is shown in Figure 1.1 As shown. It is of little significance to study its lithiation / delithiation behavior in the range of 0.0 ~ 3.0V; the amount of delithiation for the first charge can reach x = 1.2 (Li2-XMoO3), and the capacity can reach 150mA · h at 3C in the range of 1.0 ~ 4.5V / g, the lag is relatively large.

     Under the conditions of 2.0 ~ 4.5V, 10mA / g, the capacity is less than 100mA · h / g after 20 cycles. The synthesized sample should not be stored for a long time, and it will react with moisture in the air. Charge and discharge curve in the range of 1.5 ~ 4.3V, as shown in Figure 1.2.

     Li2MoO3 material has a low voltage and a stable capacity of about 90mA · h / g. It is unlikely to be applied in the field of classic liquid lithium-ion power lithium batteries.
