lifepo4 batteries Advantages:

1. Improvement of safety performance

The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat up like lithium cobalt oxide or form strong oxidizing substances, so it has good safety.

2. Improved cycle life

The cycle life of a long-life lead-acid battery is about 300 times, the highest is 500 times, while the cycle life of a lifepo4 batteries power battery is more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. Lead-acid batteries whole cycle life is 1 to 1.5 years at most, while the lifepo4 batteries used under the same conditions will have a theoretical life of 7 to 8 years.

3. Good high temperature performance

The peak value of lifepo4 batteries electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20C-75C), with high temperature resistance, lithium iron phosphate electric heating peak can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

4. Large capacity

The capacity of the battery will quickly fall below the rated capacity value when the battery is always fully charged and not discharged. This phenomenon is called the memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lifepo4 batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used at any time without having to discharge it before charging.

6, light weight

The volume of the lifepo4 batteries of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.

Disadvantages:

lifepo4 batteries also have their shortcomings: for example, poor low-temperature performance, low tap density of the cathode material, and the volume of a lithium iron phosphate battery of equal capacity is larger than that of lithium-ion batteries such as lithium cobalt oxide, so it has no advantage in miniature batteries.
