Blade batteries for energy storage

What is a blade battery?

Blade Battery 2.0 increases energy density by 30% through advanced cell-to-pack (CTP) design, eliminating bulky modules. This innovation allows more active material within the same space, boosting capacity to 204 Wh/kg.

What is a BYD blade battery?

Electrolyte additives reduce viscosity at -30°C, minimizing performance drops. BYD's Blade Battery 2.0 enhances electric vehicle (EV) performance with improved energy density, thermal stability, and safety. Using lithium iron phosphate (LFP) chemistry and structural innovations, it reduces fire risks and extends driving range.

How does blade battery work?

Blade Battery 2.0 supports 800V ultra-fast charging, achieving 10-80% charge in 18 minutes. Silicon-carbon anodes and high-purity electrolytes minimize resistance, sustaining 2C charging rates without degradation. Preheating systems adjust temperatures for optimal charging efficiency in cold climates, reducing downtime for commercial fleets.

What is a blade battery reborn?

The company’s “Battery Reborn” program enables second-life applications where retired EV batteries power solar farms and grid storage. Each recycled Blade Battery reduces CO₂ emissions by 2.3 metric tons compared to mining new materials.

How is a BYD blade battery disassembly performed?

The BYD Blade cell was opened at multiple incision points using pliers. The cells were discharged to 0% SOC before disassembly with a CCCV 0.1 C discharge procedure utilizing the AMETEK SI-9300R Battery Analyzer. Electrode probes were taken and sealed into pouch foils under an argon environment for later material analysis.

How do BYD blade cell electrodes work?

The BYD Blade cell electrodes have typical contacting flags extending out of the stack. On both sides, they are welded to a busbar, which is, in turn, connected to the outside terminal.
