Breakthrough Rechargeable-Battery Tech Is Coming out of Yonkers

Yonkers-based alpha-En Corp. is set to push the envelope of rechargeable-battery technology.

After receiving a $1 million technology development grant from the New York State Energy Research and Development Authority (NYSERDA) in July, Yonkers-based development-stage company alpha-En Corporation plans to push the envelope of rechargeable-battery technology.

“Improvement [in rechargeable batteries] over the last 30 or 40 years has been marginal; only two or three percent per year in capacity and speed of charge,” says Tom Suppanz, alpha-En Corp.’s managing director of finance. “We intend to change that.”

Batteries have three major components: an anode, a cathode, and an electrolyte. alpha-En Corp. intends to produce the lithium-metal anode part of the battery, using a patented proprietary process based on electrodeposition, which allows extraction of only lithium particles while filtering out other metals and impurities. The method is cost-efficient, environmentally friendly, and doesn’t require high temperature to conduct.

“Increased performance is ensured.”

“The more lithium you can stock into a battery, the better performance you will have,” he notes, adding that alpha-En Corp.’s anode could lead to major new developments in the ion battery.

If proven successful, the new batteries will have the capacity to power portable electronics, stationary batteries, even cars, which alpha-En Corp. founder/chairman Jerome Feldman says will be “a drastic improvement in terms of range, speed of charging, and overall performance.”

At press time, there was no scheduled date for the batteries’ release to the market.
