What is the difference between lithium iron batteries and alkaline batteries?

One: weight

Lithium iron batteries are lighter in weight than alkaline batteries.

Two: Voltage

The initial voltage of lithium iron batteries is as high as 1.8V, which is much higher than the 1.5V of alkaline batteries and the 1.2V of nickel-hydrogen batteries.

Three: Discharge

The voltage of traditional alkaline batteries decreases significantly with the extension of use time; while the discharge of lithium iron batteries has a rising situation during use.It was followed by a relatively stable discharge, but the overall voltage was still a bit higher.
