Blade battery is lithium iron phosphate

Blade battery is lithium iron phosphate. BYD officially released the blade battery, the battery will first be mounted on the "Han" model officially launched. The battery cells will be installed in an array directly on the battery pack shell, eliminating the need to install the battery cells on the module and improving the efficiency of the space inside the battery pack. BYD has been on the lithium iron phosphate battery than Cook's head of the "much loved", but the blade battery also uses lithium iron phosphate technology.

"Blade battery" through structural innovation, in the grouping can skip the "module", greatly improving the volume utilization, and ultimately achieve the design goal of putting more cells in the same space. Compared with the previous battery pack, the volume utilization rate of the "blade battery" has increased by more than 50%, which means that the range has increased by more than 50%, equivalent to the high energy density ternary lithium battery. Blade battery has high safety, long life and long range.

When the new energy market first emerged, the power battery-related route choice is actually very diverse, the mainstream choice of two types of lithium iron phosphate and ternary lithium batteries. The advantage of lithium iron phosphate batteries is high safety and long cycle life, while low energy density lithium ternary batteries are the opposite, higher energy density, but poor safety and cycle life. As one of the most important components of new energy vehicles, the power battery must of course choose the type with high safety. However, as consumers and manufacturers haphazardly shorten the range, low energy density lithium iron phosphate batteries are gradually being colded by the market, and even BYD has had to divide part of its production capacity to produce ternary lithium batteries, which is also true.

Blade type battery is a kind of lithium iron phosphate battery, but different from the past lithium iron phosphate battery. The first solution is the disadvantage of low energy density of lithium iron phosphate batteries. Energy density is actually divided into battery energy density and battery pack energy density, especially the volume of the battery pack than energy density is particularly important for cars. Previous battery pack using the "cell - battery pack - battery pack" of the layered assembly method, a variety of structures and additional components occupy a lot of space. The house we live in is full of columns and various pipes, and the space utilization rate is about 40%. On the other hand, the blade battery adopts the layered assembly method of "cell-cell", in which the cell itself is a structure, and the cell and cell can form a honeycomb aluminum' structure, so the overall strength of the cell is improved again, and the space efficiency also reaches about 60% The same space can be put into many cells, and the overall energy density is also Significantly increased.

Lithium phosphate battery without open flame, smoke, and burnt eggs on the surface of the battery; Blade type battery without open flame, no smoke, and no change in eggs on the surface of the battery. The protein solidified at 60 degrees Celsius. This means that the surface temperature of the blade cell was below 60 when the pinprick test was performed.
