The advantages of lithium manganese oxide are good rate performance, easy preparation, and low cost. The disadvantage is that the dissolution of manganese leads to poor high-temperature performance and cycling performance. By doping aluminum and sintering granulation, the high-temperature perf...

4. Long lifespan, more charging and discharging cycles are better As a general requirement, lithium iron phosphate battery packs still have 85% capacity after 2000 1C discharges, and 80% capacity after 3000 discharges. Of course, each manufacturer sets different standards du...

2. Self discharge rate of lithium iron phosphate batteries Due to the high power consumption of lithium iron phosphate batteries, it is required that the self-discharge rate of the battery pack should be less than 2% per month. To achieve this, the above consistency requirem...

1. Consistency of battery cells in lithium iron phosphate batteriesIf there is a protective plate with poor consistency in the battery cells of lithium iron phosphate batteries, according to the water bucket principle, its capacity will be manifested as the overall capacity of the lowest capacity ba...

▲ Check the battery casing. In many cases, the damage to the battery casing is due to improper battery installation, welding slag in the frame of the battery box, and low chassis caused by collision.▲ Open the cover plate to check for any traces of acid leakage around the safety valve, and then op...

1、 During the battery manufacturing process, if the following problems occur, it may lead to battery leakage: 1. When welding the battery shell and battery cover, the welding is not firm, the sealing is not good, and there are problems such as missed welding, false welding,...

Taking the preparation of electrode paste in the production process of lithium-ion batteries as an example, this is the most important step in the entire production process, as the mixing and dispersion process of electrode paste has an impact on product quality of over 30%. Why?...

Reasons for leakage of lithium-ion batteries. With the further expansion of the electric vehicle market and the continuous improvement of driving range requirements, automobile manufacturers have put forward higher requirements for power lithium batteries in terms of energy density, manufactur...

Lithium iron phosphate batteries used for communication energy storage must be combined with excellent battery management systems in order to be used safely and stably. The theoretical characteristics of lithium-ion batteries determine their sensitivity to overcharging and discharging. Due to...

Long cycle life: Charge and discharge at room temperature of 1C, and after 2000 cycles, the monomer capacity is still greater than 80%; Environmental protection: The entire production process is clean and non-toxic, and all raw materials are non-toxic. Lit...
