A power supply assembly composed of an electric storage device and an electric energy conversion device. The electric storage device includes two electrodes. The electric energy conversion device includes at least one lithium iron phosphate battery. The at least one battery is electrically connected with the electrodes. In light of this, the power supply assembly can have denser electric storage and higher discharge rate, such that power supply assembly can discharge stably, have a longer working life, and have preferable discharging effect under the low-temperature environment.
