Paving The Way For Safer, Smaller Batteries And Fuel Cells

The researchers' new structure self-assembles into hairpin shapes, resulting in acid-lined channels that allow for efficient transport of protons across the electrolyte.

Fuel cells and batteries provide electricity by generating and coaxing positively charged ions from a positive to a negative terminal which frees negatively charged electrons to power cellphones, cars, satellites, or whatever else they are connected to. A critical part of these devices is the barrier between

Better, Faster, Stronger: Building Batteries That Don't Go Boom

The diamond-tipped probe Herbert and Hackney use for their research is incredibly sensitive and must be housed in a compartment that muffles any sort of vibrations.

There's an old saying: "You must learn to walk before you learn to run." Despite such wisdom, numerous industries skip the basics and sign up for marathons instead, including the battery industry. Lithium ion batteries hold incredible promise for improved storage capacity, but they are volatile.
