1. The reason is that magnesium-ion batteries have outstanding advantages, but the disadvantages are also obvious. On the one hand, according to research, although magnesium-ion batteries have high energy density, their theoretical specific capacity is nearly 60% lower than that of lithium-ion batteries, making them difficult to apply to high-speed vehicles. new energies.
2. The selection of electrode materials is limited. The industry generally believes that the important reason limiting the rapid development of magnesium ion batteries at this stage is electrode materials, because magnesium ions have the characteristics of high charge density. , strong polarization and small size, it is difficult to insert into the matrix to form integrated compounds, leading to greater limitations in the selection of positive and negative electrode materials.
