With the further promotion of new energy vehicles, new energy vehicles exposed problems also increasingly prominent, especially the high temperature or collision spontaneous combustion and low temperature range problems caused the attention, in order to overcome the problem of battery spontaneous combustion, byd r&d introduced a blade battery, appearance is very long and thin, looks like the blade, so named "blade battery", Here's a look at the pros and cons of blade batteries.
Is the blade battery lithium iron phosphate?
The blade battery is actually called a lithium iron superphosphate battery, so called because it is arranged in such a way that the blade is inserted into the battery pack.
Blade battery is essentially lithium iron phosphate battery, but its structure and ordinary lithium iron phosphate battery is different, remove the battery module, the use of new packaging technology, higher energy density than the traditional lithium iron phosphate battery, close to the energy density of three lithium batteries, so the battery life is also improved.
What's the difference between a blade battery and a ternary lithium-ion battery?
Ternary lithium battery is a lithium ion battery whose cathode material is composed of ni, Co, Mn or Ni, Co, al in a certain ratio. As a kind of super lithium iron phosphate battery, blade battery belongs to the category of lithium ion battery like ternary lithium battery, but its cathode material is iron phosphate. Therefore, the most essential difference between blade batteries and ternary lithium batteries is the cathode material. Different cathode materials, and divide them into two different battery types.
There is a great difference between blade battery and traditional ternary lithium battery in manufacturing process. Blade battery is a kind of battery manufactured by modular process. Compared with the traditional three-element lithium battery consisting of modules, blade battery is simpler in manufacturing process, better in battery space utilization and lower in manufacturing cost.
Blade batteries are not as dense as ternary lithium batteries, but they are safer than ternary lithium batteries. Compared with the instability of ternary lithium battery, blade battery has more sufficient safety factor, and its service life is longer.
To sum up, the difference between blade battery and ternary lithium ion battery is mainly reflected in cathode material, manufacturing process, cost, mass and energy density, safety performance, service life, environmental performance and other aspects. It can be said that blade battery is superior to ternary lithium ion battery in all aspects.
