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.

What is a module-free blade battery?

The module-free Blade Battery, however, takes advantage of its blade cells to increase the volumetric energy density by up to 50%, suggesting a potential VCTPR and GCTPR of 62.4% and 84.5%, respectively. Although the Blade Battery shows a lot of promise, the blade geometry is not perfect .

Does BYD use a blade battery?

BYD is starting to use its signature blade battery in its energy storage systems, marking another major use of the battery technology in the company's business after passenger cars and electric buses.

Are blade batteries safe?

The Blade Battery’s design minimizes the risk of thermal runaway, a phenomenon that can lead to fires or explosions in lithium-ion batteries. By integrating multiple safety features, such as ceramic separators and thermal management systems, Blade Batteries offer unparalleled levels of safety for EVs and their passengers.

How does blade battery technology impact the environment?

The adoption of Blade Battery technology has far-reaching implications for the environment. As governments and industries worldwide strive to reduce greenhouse gas emissions and combat climate change, electric vehicles represent a sustainable alternative to traditional combustion engine vehicles.

Does a module-free blade battery increase volumetric energy density?

Even worse, this low volumetric energy density often requires car designers to make room for a larger pack. The module-free Blade Battery, however, takes advantage of its blade cells to increase the volumetric energy density by up to 50%, suggesting a potential VCTPR and GCTPR of 62.4% and 84.5%, respectively.
