FAQS about Blade battery energy storage system composition diagram

What is a blade battery?

The structure of the Blade Battery from cell to pack. At the center of the design of the Blade Battery is the cell geometry, which has a much lower aspect ratio compared with conventional cylindrical or prismatic cells. According to BYD’s patents, the cell depth (Z axis) is 13.5 mm while the cell length (X axis) can range from 600 mm to 2500 mm.

Why did BYD create a blade battery?

Believing this an impractical path, BYD puts the spotlight back on safety and stability in presenting the Blade Battery. In pushing toward a safer electric vehicle battery design, BYD realized that it needed to package LiFePO4's inherent stability and safety advantages into a battery pack with energy capabilities comparable to lithium-ion.
