4 FAQs about Blade battery energy storage system structure diagram

What is a blade battery?

Over the past several years, the Blade Battery has earned its place as one of the safest and most durable EV battery technologies in mass production. The defining feature of the Blade Battery is its distinctive long-cell structure. Each cell is designed in a slim, elongated format that resembles a blade—hence its name.

Are blade batteries thermally stable?

Regarded as the most stringent test for evaluating thermal runaway, the Blade Battery remains stable without smoke or fire even under direct puncture—an outcome that many NCM and standard LFP cells fail to achieve. Blade cells remain thermally stable at temperatures where other chemistries begin to decompose or emit gases.

What is the difference between a module and a blade battery?

The height of the Blade Battery is reduced by ~50 mm, compared with regular LFP battery back with modules, providing more space to the passengers and decreasing the coefficient of drag (0.233 cd for BYD Han). In the Z direction, the structure of the Blade Battery is completely different from conventional module-based battery packs (Figure 3).

What makes the blade battery unique?

The Blade Battery aligns naturally with global decarbonization goals thanks to both its chemistry and its manufacturing ecosystem. LFP chemistry avoids nickel and cobalt, reducing dependence on materials linked to higher mining impact.
