The blade battery, a power cell that Warren Buffett-backed Chinese electric car company BYD claims won't catch fire, was first used in its flagship Han EV model. It is now available in all BYD's all-electric models.
In addition to the Han EV, BYD's entire pure electric car lineup is now equipped with the blade battery, jiemian.com reported Sunday, citing a company meeting transcript.
BYD also said it is now aggressively expanding its production capacity to cope with future sales increases and supply to external customers, the report said.
Last March, BYD unveiled its new lithium iron phosphate battery - the Blade Battery - which passes all safety tests, even the most difficult pinprick test done by the company.
Because of its narrow profile, the blade battery dramatically improves battery volume utilization and allows for more battery capacity to be installed in a limited space.
Lithium iron phosphate as the electrode material is safer compared to 811 ternary lithium battery material.
In the past few years, China's pure electric vehicle models in the battery selection will generally choose a higher energy density of ternary lithium batteries, lithium iron phosphate is more often found in the commercial vehicle sector.
In the past two years, the safety of ternary lithium batteries has been questioned as the number of electric vehicle fires has increased.
BYD's unique packaging mode allows the blade battery energy density to catch up with the mainstream ternary lithium battery.
Compared with ternary lithium batteries, lithium iron phosphate batteries have lower cost and better safety. Driven by BYD's blade battery usage, several car companies have now chosen lithium iron phosphate batteries.
