6.How does lithium iron phosphate battery work?

The working principle of the lithium iron phosphate battery involves the movement of lithium ions through the electrolyte. These ions passed across the polymer separator. When the battery is in the use, lithium ions from the anode go to the cathode and are collected at the cathode. This results in the production of free electrodes at the anode and also in the creation of charge at the current collector.
 
The electric current then passes from the current collector and goes to the device or machinery which consumes this electric current. After that, the electric current flows to a negative current collector. The separates prevent the movement of electrons within the battery. Charging/Discharging of Battery
In discharging mode, the battery is producing an electric current which is used to power a vehicle or device. The anode passes lithium ions to the cathode leading to the generation of electrons at the anode.
These electrons flow across the other side to the cathode. All lithium ions are intercalated at the cathode in full discharge.
When you charge your device, the opposite movement of lithium ions occurs. Oxidation reaction takes place at the cathode. It releases its electrons and to balance the charge, the lithium ions go from cathode to anode.

7.What is the difference between lithium-ion and lithium iron phosphate batteries?

Lithium-ion and lithium iron phosphate both are made up of same key element lithium-ion, but there are major differences between these two batteries.
