Abstract
A power supply circuit, a charging-discharging circuit and an intelligent terminal are provided. The power supply circuit includes a lithium-ion battery unit having a silicon anode and a lithium-ion battery unit having a carbon anode. The lithium-ion battery unit having the silicon anode is connected in series with the lithium-ion battery unit having the silicon anode, cooperatively supplying power to the to-be-powered unit. A battery system of the intelligent terminal is formed by the lithium-ion battery unit having the silicon anode and the lithium-ion battery unit having the carbon anode and supplies power to the to-be-powered unit. Therefore, constant voltage performance of the lithium-ion battery unit having the carbon anode is utilized effectively, further large capacity and large power margin at low supply voltage of the lithium-ion battery unit having the silicon anode is utilized effectively.
