The BYDblade battery is a lithium iron phosphate (LFP) battery for electric vehicles, designed and manufactured by FinDreams Battery, a subsidiary of Chinese manufacturing company BYD. [1] [2] [3]

The blade battery is most commonly a 96 centimetres (37.8 in) long and 9 centimetres (3.5 in) wide single-cell battery with a special design, which can be placed in an array and inserted into a battery pack like a blade. It is made in various lengths and thicknesses. The space utilization of the battery pack is increased by over 50% compared to most conventional lithium iron phosphate block batteries.

The blade battery was officially launched by BYD in 2020. BYD claims that compared with ternary lithium batteries and traditional lithium iron phosphate batteries, the blade battery holds advantages in safety, range, longevity, strength and power.

Safety

BYD claims that, in the nail penetration test, the blade battery emitted no smoke or fire after being penetrated, and its surface temperature reached only 30 to 60 °C (86 to 140 °F). The blade battery also passed other extreme test conditions, such as being crushed and bent, being heated in a furnace to 300 °C (572 °F), and being overcharged by 260%. None of these resulted in a fire or explosion. [4]

BYD claims that "EVs equipped with the blade battery would be far less susceptible to catching fire – even when they are severely damaged." [1] [4]

In July 2021, a BYD Han EV with blade batteries was crash-tested in China (car-to-car crash test) versus an Arcfox Alpha-S. About 48 hours after the test, the BYD Han was producing smoke and allegedly caught on fire. BYD argued that the fire was due to the misuse of battery coolant. Specifically, the "red" coolant used was identified as electrically conductive, which caused further reaction when the blade battery and wirings were damaged. The standard battery coolant used in the Han is "purple", which is not conductive. BYD also stated the testing was "not mainstream, non-authoritative, and not within the industry standard", and wishes for the media to communicate with the company to understand the specification to the car before testing for a more objective and reasonable result.

<span class="mw-page-title-main">Lithium iron phosphate battery</span> Type of rechargeable battery

The lithium iron phosphate battery or LFP battery is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% were from EV makers Tesla and BYD alone. Chinese manufacturers currently hold a near monopoly of LFP battery type production. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.

<span class="mw-page-title-main">Plug-in electric vehicle fire</span> Type of vehicle incident

Numerous plug-in electric vehicle (EV) fire incidents have taken place since the introduction of mass-production plug-in electric vehicles. As a result of these incidents, the United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) conducted a study in 2017 to establish whether lithium-ion batteries in plug-electric vehicles pose an exceptional fire hazard. The research looked at whether the high-voltage batteries can cause fires when they are being charged, and when the vehicles are involved in an accident.

Regarding the risk of electrochemical failure, [this] report concludes that the propensity and severity of fires and explosions from the accidental ignition of flammable electrolytic solvents used in Li-ion battery systems are anticipated to be somewhat comparable to or perhaps slightly less than those for gasoline or diesel vehicular fuels. The overall consequences for Li-ion batteries are expected to be less because of the much smaller amounts of flammable solvent released and burning in a catastrophic failure situation.
