Working Principle of 1.5V Li-FeS2 Battery

 

The 1.5V Li-FeS2 battery works based on the principles of electrochemistry. The battery consists of a cathode, an anode, and an electrolyte. The cathode is made up of iron disulfide (FeS2), and the anode is made up of lithium metal (Li). When the battery is connected to a circuit, the lithium ions from the anode migrate towards the cathode, while electrons flow through the circuit. The lithium ions react with the FeS2 in the cathode, releasing energy and forming lithium sulfide (Li2S) and iron (Fe) as the products of the reaction.
