In nan ever-evolving scenery of electrical vehicles (EVs), nan quest for safer, much reliable artillery technologies has go paramount. A caller breakthrough study from nan University of Texas astatine Austin’s Cockrell School of Engineering unveils a promising solution: sodium diluent arsenic nan cardinal to mitigating nan consequence of fires sparked by EV batteries.

How Common Are Lithium Battery Fires?

Since lithium-ion batteries usage flammable materials, they tin create a “thermal runaway” wherever changeless voltage charging tin lead to uncontrollable somesthesia increases that commencement a fire. While this arena is unlikely, erstwhile it does occur, it is hazardous.

A CNN report from earlier this period notes that aggregate fires astir North America this period are linked to products that usage lithium-ion batteries. One lawsuit of this was a five-alarm occurrence successful New York City, of which New York Fire Department Commissioner Laura Kavanagh told nan media outlet, “In each of these fires, these lithium-ion fires, it is not a slow burn; there’s not a mini magnitude of fire, it virtually explodes.”

While their study links lithium-ion artillery products specified arsenic e-bikes and e-scooters to these fires, lithium-ion batteries powerfulness astir EVs. So, while EV artillery fires are rare, they are still a plausible danger. Especially fixed that American consumers purchased 1.2 million EVs past twelvemonth – that’s a batch of lithium-ion batteries connected US roadways and charging astatine American homes.

UTA’s Sodium Battery

The researchers astatine nan Cockrell School of Engineering utilized a sodium nitrate-based diluent arsenic a nonflammable solvent successful nan electrolyte, importantly stabilizing nan full battery. The project’s lead researcher, Professor Arumugam Manthiram of nan Cockrell School of Engineering, said of this caller sodium battery, “Batteries drawback occurrence because nan liquid solvents successful nan electrolyte don’t get on pinch nan different parts of nan battery. We person reduced that consequence from nan equation to create a safer, much unchangeable battery.”

Manthiram explained why this caller artillery is simply a amended replacement to lithium-ion, “Here we show a sodium artillery that is safe and inexpensive to produce, without losing retired connected performance. It’s captious to create alternatives to lithium-ion batteries that are not conscionable connected par pinch them, but better.”

Additionally, manufacturers tin find sodium worldwide, making it much environmentally friends than mining for lithium and cobalt. Sodium batteries tin besides usage little costly existent collectors for their electrodes, specified arsenic aluminum. Lithium uses copper, which is simply a little sustainable material. Sodium batteries are astir 30 percent little costly than lithium ones, which intends that sodium batteries tin make EVs cheaper to manufacture and safer overall.
