We make batteries better.



performance additives

These are additives to the active material of a battery to improve performance characteristics. HGI offers additive solutions that are custom tailored to our customer's specific needs. Applications include automotive, motive traction, stationary, and advanced partial state of charge (PSoC).


Powdered oxide

In addition to the company’s traditional automotive and industrial battery business, Hammond Group has developed a variety of specialty lead chemicals for glass, ceramics, and the electronics market. These include battery oxides, specialty oxides, lead silicates, and lead borates. 

Glass & Dispersions

These are low-melt glass products, in granular, flake and powder form. Hammond produces this broad spectrum of lead and heavy metal free (HMF) technical materials in dedicated systems, preventing the potential for cross-contamination. Hammond has the capability to produce in large and small volume batches, as well as continuous melt processing.
