A US-based company, Amionx, has launched a new technology that would make lithium-ion batteries safer. This technology, known as Safe Core, will shut down faulty cells in the battery before they catch fire.
According to the company (an offshoot of American Lithium Energy), Safe Core acts as a fuse that kills the battery cells when they get too hot or exceed their voltage thresholds. This usually occurs from physical damage, overcharging or exposure to high temperatures. Current lithium-ion batteries include a hardened outer shell and fire retardant chemicals. On the contrary, Safe Core works from the inside out, shutting down the cell before it gets to a critical temperature.
The Safe Core technology was originally developed through US army-funded programs. American Lithium Energy used the technology to create batteries for the US Army that would not explode even if they were hit by gunfire.
Last year, Samsung released the Galaxy Note 7, which was supposed to be the company’s flagship device. This was not to be. Due to faults in the battery, a number of Note 7 units caught fire while charging. Samsung had to recall millions of Note 7 devices worldwide. It wasn’t until recently that the Korean smartphone maker explained why the Note 7 units caught fire.
Hopefully, the tech giants will borrow a leaf from Amionx’s book in their smartphone battery design.
