Millions of problems with lithium
Ion batteries can cause many fires because there are billions of batteries in use now and dozens of batteries sometimes pile up in one device.
Experts say lithium
Ion batteries are more dangerous because their electrolyte, the liquid that allows the ions to move between the electrodes in the battery, is more flammable than the substance in the old-fashioned battery.
These old types include leads.
Acid batteries in most cars and nickel
Cd batteries often used in video equipment and power tools.
Still, Gerbrand Ceder, professor of materials science and engineering at MIT, and others said that safety issues can be solved.

Ion batteries can be repaired for major efficiency and storage improvements.
Amatucci says he thinks we can get two to three times the energy from the lithium in the future.
Others say that small chemical changes can even play a bigger role.
