POSTECH scientists just dropped a bombshell: swapping some nickel for aluminum in EV battery cathodes could mean longer-lasting, safer, and more affordable electric cars. This tweak could help end the thermal runaway risk and make batteries cheaper to produce. But will aluminum really dethrone nickel as the go-to for high-performance batteries, or are we just trading one problem for another? Would you trust your next EV with this new tech? #Tech #EVs #BatteryTech
