The actual life of lithium iron phosphate battery is 3000 times.
According to relevant experiments, it can be known that lithium iron phosphate batteries still have 95% capacity after being charged 2,000 times, and their design life reaches more than 3,000 times. considering that phosphoric acid The actual life of lithium iron battery is 3,000 times. Of course, improper charging or use will affect the life of most lithium iron phosphate batteries.
On the left side of the lithium iron phosphate battery is the positive electrode made of LiFePO4 material with an olivine structure, which is connected to the positive electrode of the battery by an aluminum foil. On the right is the negative electrode of the battery made of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil. In the middle is a separator ppolymer which separates the positive electrode from the negative electrode. Lithium ions can pass through the separator but electrons cannot pass through the separator. The battery is filled with electrolyte and the battery is sealed by a metal case.
Characteristics of lithium iron phosphate batteries
1 High energy density
According to reports, square aluminum is produced in series in 2018. The energy density of a lithium iron phosphate battery is approximately 160 Wh/kg. In 2019, some excellent battery manufacturers can probably achieve 175-180 Wh/kg. Some powerful manufacturers use lamination technology to increase capacity, or can achieve. 185 Wh/kg.
2. Good safety performance
The electrochemical performance of the cathode material of the lithium iron phosphate battery is relatively stable, which determines that it has astable charging and discharging platform. the process of charging and discharging, the battery structure will not change, it will not burn or explode, and it remains very safe even under special conditions such as short circuit, overcharge, extrusion , acupuncture, etc.
3. Long lifespan
The 1C lifespan of lithium iron phosphate batteries generally reaches 2,000 times, or even more than 3,500 times, while the energy storage market requires more than 4,000 times. 5,000 times. It guarantees a lifespan of 8-10 years, which is more than 1000 times the lifespan of ternary batteries, while the lifespan of long-life lead-acid batteries is about 300 times .
