How Hard Is Lithium-Air Battery Research? Pretty Tough, Actually

Green Car Reports

It''s hard to keep track of all the future battery technology candidates, but lithium-air battery technology is among the most widely-researched. Its biggest draw is the potential to store three times the energy in batteries the same size and weight of today''s electric vehicles--providing huge increases in range.

Volkswagen To Triple Battery Capacity With Lithium-Air Technology?

Green Car Reports

So far, scientists have struggled to find batteries for electric cars that match the huge amounts of energy stored in a gallon of gasoline or diesel. As a result we get big, heavy batteries with relatively short Fossil fuels may not be the cleanest way of powering us between two points on a map, but there''s little doubt they offer convenience.
