EnerSys of Reading has become the largest producer of batteries for the U.S. space industry.
EnerSys has purchased a southern California company, Quallion LLC, for $35 million. Quallion is a manufacturer of implantable and external lithium ion batteries for the medical device industry.
"With the United States government's … investment of $65 million in Quallion's cathode and anode production equipment, we will have the capability to produce lithium ion materials and for satellite batteries," said John D. Craig, chairman, president and CEO of EnerSys.
Richard Zuidema, executive vice president of EnerSys, said the acquisition also expands the EnerSys footprint into the medical device market, which he called a rapidly growing market.
Zuidema said Quallion will become part of EnerSys, with Quallion's products becoming part of the EnerSys Quallion line.
Quallion, which has 100 employees, will remain in California.
