Scientists have developed a promising new material used in battery design, which works in a similar way to soap in removing grease and dirt.
A recent study published in the journal Nature Materials explained that highly concentrated local electrolytes (electrolytes) could be the “missing piece” that completely opens the door to designing longer-lasting batteries.
The key to long-lasting batteries may lie in understanding how soap gets rid of dirt, as it forms tiny structures called micelles that act as a bridge between water and what is being cleaned by wrapping it into tiny structures.
Scientists from Brown University said that a similar process occurs in highly concentrated electrolytes, described as one of the most promising materials for battery design.
Electrolytes are essential in the energy storage process because they allow the electrical charge to pass between the two ends of the battery. This triggers the chemical reaction needed to convert stored chemical energy into electricity.
Batteries made of lithium metal have a greater energy storage capacity than current lithium-ion batteries.
But the researchers explained that the electrolytes typically used to power lithium-ion batteries do not do so as effectively in metal batteries.
“We want to improve and increase the energy density of batteries, meaning how much energy they store per cycle and how many cycles the battery lasts,” said study co-author Yu Qi, of Brown University. To do this, the materials inside traditional batteries must be replaced to make the batteries long-lasting. "That stores more energy is a reality - think of batteries that can power a phone for a week or more, or electric cars that go 500 miles."
