BYD's Breakthrough in Extending the Range of LiFePO4


In the realm of electric vehicles (EVs), the choice between long-range but safety-compromised ternary lithium batteries and safe yet short-range lithium iron phosphate (LiFePO4) batteries has long been a challenge for automakers. However, BYD's introduction of blade battery technology in March 2020 has transformed the landscape of EV battery technology. With claims of overcoming the low energy density disadvantage of traditional LiFePO4 batteries, BYD aims to shift the industry's reliance away from ternary lithium batteries.

BYD Vice President and Chairman of Blade Battery, He Long, stated, "All major automotive brands are discussing cooperation plans with us based on the 'blade battery' technology." Indeed, BYD's blade batteries began supplying Tesla in August 2022 and were installed in Model Y vehicles at the German factory by the end of August.

This collaboration between competitors underscores the competitive edge of blade batteries. In late October of the same year, BYD once again broke through the range limitation with vehicles equipped with blade batteries achieving a range of up to 700 kilometers, making them suitable for medium to long-distance travel.

The key to BYD's success lies in the redesign of the battery's energy density, eliminating the module frame and reinforcement beams to increase the utilization rate of the battery pack. This innovation minimizes wasted space and bulkiness, allowing BYD to achieve longer ranges with LiFePO4 batteries.

BYD also claims that vehicles on its 3.0 platform equipped with blade batteries will achieve a range of up to 1000 kilometers, challenging the conventional perception of LiFePO4 battery range limitations.

Powerful and reliable batteries are the cornerstone of EVs and energy storage devices, akin to the heart that determines the performance of the equipment. CTECHI's portable emergency energy storage stations, utilizing the same standardized blade batteries as BYD electric vehicles, offer enhanced safety, sophistication, and coordination. With meticulous attention to detail and rigorous testing, CTECHI's products represent a fusion of technology and artistry, delivering surprises in every aspect.
