Lithium iron phosphate battery (LiFePO4) has a nominal voltage of 48VDC. It is comprised of 16 cells of 3.2V each. The internal structure of the LiFePO4 battery cell is shown in the figure on the right. Shown is the olivine structure of LiFePO4 as the positive electrode of the cell. Aluminum foil functions as a current collector of the positive pole. A polymer membrane separates positive and negative electrodes of the cell. The electron (e-) can't pass through the polymer separator but Li+
Features of Lifepo4 Battery
- Long cycle life: Offers to 20 times longer cycle life and five times longer float/calendar life than a lead-acid battery, helping to minimize replacement cost and reduce total cost of ownership
- Lighter Weight: About 40% of the weight of a comparable lead-acid b battery. A" drop-in" replacement for lead-acid batteries.
- Higher Power: Delivery Twice power of the lead-acid battery, even high discharge rate, while maintaining high energy capacity.
- Wide Temperature Range: -20℃-60℃
Superior Safely: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging, or short circuit situations.
- Increased Flexibility: Modular design enables deployment of up to four batteries in series and up to ten b batteries in parallel.

FAQ:
Q:What is special about lithium batteries?
A:With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume
Q:What is a lithium battery used for?
A:Lithium battery use for power and energy storage. Like emergency power backup or UPS. Dependable electric and recreational vehicle power,golfcart,reliable and light-weight marine,solar power storage,surveillance or alarm systems in remote locations.
Q:What is the difference between a lithium battery and a lithium-ion battery?
A:It mostly comes down to the fact that lithium-ion batteries are rechargeable while lithium batteries are single-use. Lithium battery have a higher energy density than lithium ion batteries.
Q:Which battery is better alkaline or lithium?
A:Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.A lithium battery can be used as a high-performing alternative to a standard alkaline battery. Lithium battery designed to last longer,making them a good choice for high-tech and smart devices. They can withstand extreme low temperatures. Lithium can operate without failing in a very cold climate, so it’s ideal for outdoor applications.
