BYD Blade Battery Technology for Enhanced Safety and Longevity

Lithium iron phosphate (LFP) batteries face persistent challenges in achieving both high energy density and long-term stability. Traditional LFP cells typically achieve specific capacities of 140-150 mAh/g, with particle morphology and conductivity limitations affecting their performance. BYD's blade battery technology represents a systematic approach to these fundamental constraints.

The core challenge lies in optimizing particle density, uniformity, and conductivity while maintaining the inherent safety advantages of LFP chemistry.

This page brings together solutions from recent research—including mixed-morphology particle engineering, controlled atmosphere sintering processes, and novel carbon-composite structures. These and other approaches demonstrate how manufacturing innovations are enabling higher energy density while preserving LFP's thermal stability advantages.
