Quallion

Quallion is a specialized manufacturer of high-performance lithium-ion batteries designed for the medical, aerospace, and defense sectors. The company is particularly recognized for its expertise in developing miniaturized, implantable power sources for life-critical medical devices, including neurostimulators, cardiac pacemakers, and cochlear implants. A key technological differentiator is Quallion's proprietary Zero-Volt technology, which enables batteries to be fully discharged to zero volts and stored without losing capacity or safety performance. Founded by renowned entrepreneur Alfred Mann, the company provides end-to-end services from custom cell design to large-scale manufacturing. In 2013, Quallion was acquired by EnerSys, a global leader in stored energy solutions, where it continues to operate as a center of excellence for medical and specialty battery applications.
