SIGRACELL® additives for lead acid batteries

Contact 0

Lead acid batteries are the most commonly used and most advanced battery type. They are used as short- and medium-term energy storage systems, for example as starter batteries and traction batteries for vehicles, as well as for uninterruptible power supply.

Designed according to the latest research results, SIGRACELL^® materials significantly improve battery performance.

Key advantages of our materials:

Significant improvement of Dynamic Charge Acceptance (DCA)
High cycling stability
Very low levels of metal impurities
Excellent wettability
Easy to mix into the lead paste
Combination with conductive carbon blacks possible

Our own focus on research as well as our extensive Research and Development network put us at the forefront of material development. This allows us to integrate the most recent scientific findings into our production of additives.

We provide tailor-made solutions featuring an enhanced dynamic charge acceptance (DCA) in combination with low hydrogen development and improved cold-crank-ability.

We offer a large portfolio of additives for lead acid batteries based on synthetic graphite, natural graphite and carbon fibers. We ensure the best solutions for our customers, with products that combine electrical conductivity, high purity and optimized particle shape.
