Are aluminum iron phosphate batteries blade batteries?

The Pacific Automotive Network iron aluminum phosphate battery is a blade battery. The blade battery is actually a long-shaped power battery with each battery cell, compared to the box-shaped cube of the traditional power battery cell. The shape of the blade battery cell is long and thin and looks like a watermelon knife, so it is called a blade battery.

The blade battery is a lithium iron phosphate battery, so there are three basic structures inside each battery: cells, modules, and batteries. The cells and modules of traditional lithium iron phosphate batteries require the attachment of supports, so the volume is relatively large. However, the blade battery eliminates these carriers and directly packs the cells, which makes the energy density of the blade battery higher than that of the blade battery. same volume. Generalent, the energy of lithium iron phosphate batteries is 50% higher.

Easy to pass the acupuncture test. Since the blade battery has a long strip structure, there is a long distance between the positive and negative electrodes, which can effectively reduce the heat generated during internal reactions and the probability of internal short circuit. Even weaker.

When the blade battery was launched, BYD officials released acupuncture test videos on ordinary lithium iron phosphate batteries and blade batteries: test results of the ternary battery lithium were violent combustion, with a surface temperature above 500 ° C, the eggs on the surface of the battery were blown away.

The test results of the lithium iron phosphate battery showed that there was no open flame or smoke, the surface temperature rose to 200°C ~ 400°C, and that the eggs onthe surface of the battery was burned.

The test result of the blade battery is that there is no open flame, no smoke, the surface temperature is 30°C ~ 60°C, and it does not There is no change in the eggs on the surface of the battery.

Such a result means that if a traffic accident damages the power battery, the blade battery will have a lower probability of explosion and spontaneous combustion than ordinary lithium iron phosphate batteries.
