Power supply circuit, charging-discharging circuit and intelligent terminal

A charging-discharging circuit, comprising a charging circuit and a power supply circuit,

• wherein the power supply circuit comprises:
• a power supply battery unit, comprising a lithium-ion battery unit having a silicon anode and a lithium-ion battery unit having a carbon anode, wherein the lithium-ion battery unit having the carbon anode is connected in series with the lithium-ion battery unit having the silicon anode, and the lithium-ion battery unit having the silicon anode and the lithium-ion battery unit having the carbon anode are capable of cooperatively supplying power to a to-be-powered unit;
• and
• an input end of the charging circuit is connected to a power source, and the charging circuit is electrically connected to the power supply battery unit to charge the power supply battery unit.

An intelligent terminal, comprising:

• a to-be-powered unit;
• and
• a power supply circuit, electrically connected to to-be-powered unit to supply power for the to-be-powered unit, wherein the power supply circuit comprises:
• a power supply battery unit, comprising a lithium-ion battery unit having a silicon anode and a lithium-ion battery unit having a carbon anode, wherein the lithium-ion battery unit having the carbon anode is connected in series with the lithium-ion battery unit having the silicon anode, and the lithium-ion battery unit having the silicon anode and the lithium-ion battery unit having the carbon anode are capable of cooperatively supplying power to a to-be-powered unit.
