LiFePo4 Battery

Lithium iron phosphate batteries generate heat normally, but cannot lose control of heat. If thermal runaway occurs. The main reason is that the battery selection and thermal design are unreasonable, or there is an external short circuit.

1. The battery management system has incomplete safety functions for overcharged circuits, resulting in the BMS losing control and still charging.
   
   
2. Impurities in battery production, metal particles, contraction caused by charging and discharging expansion, lithium precipitation, and other factors can lead to internal short circuits.

Not same. Each lithium iron phosphate battery manufacturer is different, with different production processes, capacities, and sizes. In addition, even for the same model of battery, there are different specifications of batteries such as A grade, B grade, and disassembled batteries from other equipments.

Sure, many cars are trending to use 12V lithium iron phosphate battery pack as their starting power. Due to its high energy density and low self discharge, the car can be parked for a long time in a certain location, so don't worry about not being able to start the car.

Firstly, we need to clarify that the main causes of battery explosions are overcharging, over discharging, and short circuit. If used correctly, stored, and charged and discharged, lithium iron phosphate batteries are less likely to explode.

Secondly, lithium iron phosphate batteries have the characteristic of higher safety compared to other lithium-ion batteries. Compared with lithium cobalt oxide batteries, lithium iron phosphate batteries have a higher thermal runaway temperature, as well as better stability and shock resistance. Compared with ternary material batteries, lithium iron phosphate batteries have lower costs, making them a lithium-ion battery with excellent safety and cost performance.

Finally, even if there are abnormal situations in lithium iron phosphate batteries, there are some measures to avoid or reduce the risk of explosion. For example, for chargers, products that meet the specifications of lithium iron phosphate batteries should be selected. For storage, overcharging and discharging should be avoided to avoid deformation and short circuits. In case of abnormalities during use, the battery should be quickly stopped and not discarded or burned directly.

In summary, although lithium iron phosphate batteries are not 100% safe, as long as they are used, stored, charged and discharged correctly, and maintained regularly, the risk of explosion is relatively small.

#1. Ensure that the lithium iron phosphate battery cell matches the voltage, internal resistance, and capacity.

#2. Connect all positive poles together and all negative poles together.

#3. Connect BMS to monitor the status of each battery, ensuring safety and performance.

#4. Check the status of parallel batteries to ensure that the battery pack is working properly.

Lithium iron phosphate battery, also known as lithium iron phosphate lithium-ion battery, refers to a lithium-ion battery that uses lithium iron phosphate as the positive electrode material. Lithium iron phosphate is mainly composed of lithium iron phosphate, which has much more Earth reserves and lower costs compared to rare metals such as nickel, cobalt, manganese, phosphorus, and iron. Therefore, why is it called lithium iron phosphate battery? It's because its positive electrode material is lithium iron phosphate.

Advantages: The charging and discharging rate is also relatively high, with good safety and high temperature resistance. Another major advantage is that the cost is relatively low.

The disadvantage is that the energy density is relatively low, the volume density is relatively low, and at the same time, in cold weather conditions, its range attenuation may be more.

Safety: The natural temperature of lithium iron phosphate batteries is 800℃. The reason why lithium iron phosphate is safer is that the ignition point of this material is higher.

Typically last 5 to 10 years when properly used, with approx 6000+ charge cycles.

Yes, in the long run it is worthy because the Lifepo4 battery pack has many advantages over traditional batteries.
