What is 1.5V Li-FeS2 Battery
The 1.5V Li-FeS2 battery uses lithium as the anode, iron disulfide as the cathode, and a lithium salt in an organic solvent mixture as the electrolyte. Working voltage 1.5V, high energy, light weight, good performance under high and low temperature conditions. Its operating voltage is 1.5V and is commonly used in low-power devices such as remote controls, electronic toys, and alarms. Li-FeS2 batteries have a long shelf life and can operate over a wide temperature range.
Advantages of 1.5V Li-FeS2 Battery
Low temperature resistance
This type of battery has greater effect advantages at low temperatures and has excellent low-temperature performance. Making it an ideal battery choice for extremely low temperatures.
Wide operating temperature range
Suitable for use in extreme environments due to wider operating temperature range and low weight. The 1.5V Li-FeS2 battery can operate in a range of temperatures, from as low as -40°C to as high as 60°C.
High energy density
1.5V Li-FeS2 battery offer a high energy density, meaning they can store more energy per unit mass or volume. This allows for longer run times and smaller form factors.
Low self discharge rat
These batteries have a low self-discharge rate, which means they lose very little charge over time when not in use. This improves their overall reliability and performance.

Material of 1.5V Li-FeS2 Battery
The cathode of a 1.5V Li-FeS2 battery is typically made from iron disulfide (FeS2). The anode is made from lithium metal. The electrolyte used in the battery is typically a solution of lithium perchlorate (LiClO4) in a mixed solvent of propylene carbonate (PC) and dimethyl carbonate (DMC). The outer casing of the battery is usually made from a combination of plastic and metal.


Components of 1.5V Li-FeS2 Battery
It consists of positive electrode, negative electrode, electrolyte, separator, positive electrode lead, negative electrode lead, center terminal, material, safety valve, sealing ring, positive electrode temperature control terminal, battery shell, etc.
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.

What You Should Know When Use 1.5V Li-FeS2 Battery
Avoid direct sunlight
Batteries should be stored in a dry, cool place away from direct sunlight and extreme heat or cold. The recommended storage temperature range is -20℃ to 25℃.
Pay attention to the discharge time
Avoid completely discharging the battery as this will shorten battery life. Discharging a battery beyond recommended levels may also cause leakage, fire, or explosion.
Pay attention to the temperature range
The optimal operating temperature range of 1.5V Li-FeS2 battery is -40℃ to 60℃. Using the battery outside this temperature range may damage the battery and reduce its performance.
Recycling
Dispose of the battery properly by recycling it through a qualified recycling facility. Do not dispose of the battery in fire or water as it may cause harm to the environment.
