Most of today’s electric vehicles (EVs) are powered by lithium-ion (Li-Ion) batteries—the same kind of batteries used in cell phones and laptop computers. Currently, most Li-ion batteries used in EVs provide a driving range limited to 100 miles on a single charge and account for more than half of the total cost of the vehicle. To compete in the market with gasoline-based vehicles, EVs must cost less and drive farther. An EV that is cost-competitive with gasoline would require a battery with twice the energy storage of today’s state-of-the-art Li-Ion battery at 30% of the cost.
Project Innovation + Advantages:
Xilectric is developing a totally new class of low-cost rechargeable batteries with a chemistry analogous to the original nickel-iron Edison battery. At the turn of the 20th century, Thomas Edison experimented with low-cost, durable nickel-iron aqueous batteries for use in EVs. Given their inability to operate in cold weather and higher cost than lead-acid batteries, Edison’s batteries were eventually dismissed for automotive applications. Xilectric is reviving and re-engineering the basic chemistry of the Edison battery, using domestically abundant, environmentally friendly, and low-cost metals, such as aluminum and magnesium, as its active components. Xilectric’s design would be easy to manufacture and demonstrate longer life span than today’s best Li-ion batteries, enabling more widespread use of EVs.
If successful, Xilectric’s reinvented Edison battery would demonstrate lower-cost and longer life than today’s best Li-Ion batteries at 25% of the manufacturing cost.
Increased use of EVs would decrease U.S. dependence on foreign oil—the transportation sector is the dominant source of this dependence.
Greater use of EVs would reduce greenhouse gas emissions, 28% of which come from the transportation sector.
This battery would enable an EV to travel from Chicago to St. Louis (300 miles) on a single charge, for less than $10 on average.
