No More Fires? MRI Scans of Batteries Show Explosive Potential

What looks like the liquid android from 1991's "Terminator 2: Judgment Day" stuck in the spin cycle is actually the insides of a lithium-ion battery. It might be a way to monitor rechargeable batteries in real time, preventing loss of performance and runaway explosions. "We believe these methods could become important techniques for the development of better batteries," study researcher Alexej Jerschow, a chemistry professor at New York University, said in a statement.
