Future Batteries, by the Numbers - To take EV batteries to the next level, materials scientists are examining a wide...

After a decade of intense focus on lithium-ion, material scientists are beginning to look to new battery chemistries for future electric cars. The new chemistries could require a long wait -- 10 or 20 years in some cases -- but they might change the future of electric transportation. "We're getting to the end of the road as far as being able to extract more energy out of lithium-ion," John Kopera, vice president of commercial operations for Sion Power , a maker of lithium-sulfur batteries, told us. "But we can see a time when batteries could have higher energy, weigh less than half as much, and still be less costly than lithium-ion." Sion Power isn't alone in believing better battery chemistries are on the horizon. The Advanced Research Projects Agency (ARPA-e) has tabbed a variety of chemistries for government-sponsored development through its Batteries for Electrical Ene...
