High performance acetylene black for lithium-ion batteries

Orion Engineered Carbons S.A. is launching the first high-performance acetylene black, PRINTEX kappa 100, for lithium-ion batteries.
Based on acetylene gas, PRINTEX kappa 100 offers conductive functionalities that improve lithium-ion battery performance. Acetylene black aggregates form a three-dimensional network to lower the internal resistance of battery cells by enhancing conductivity, ensuring that charge and discharge processes are performed effectively and Ohmic losses are minimized.
Compared to other carbon black, acetylene black’s high-intrinsic electronic conductivity and purity leads to significantly higher power densities and longer battery lifecycle. These advantages result from acetylene as pure feedstock and its thermal decomposition at very high temperature.
“As a result of very high production yield, our acetylene black has a remarkably low carbon footprint,” said Sandra Niewiem, Ph.D., senior vice president, Global Specialty Carbon Black and EMEA Region, at Orion.  “We’re pleased to provide materials that not only improve the conductive performance of lithium-ion and lead-acid batteries but also, in the case of PRINTEX kappa 100, contribute to the reduction of greenhouse gas emissions.”
Increasing DCA in Advanced Lead-Acid Batteries
The PRINTEX kappa 210, PRINTEX kappa 220 and PRINTEX kappa 240 grades increase the dynamic charge acceptance (DCA) of advanced lead-acid batteries by up to 60 per cent, while maintaining acceptable water loss. They have very low metallic impurities, which results in extended battery cycle life.
The modified surface of these PRINTEX kappa grades maintain conductivity and surface area while suppressing the hydrogen evolution reaction, lowering water loss to acceptable levels. This surface modification gives battery manufacturers the freedom to use higher loading to achieve higher charge acceptance. Orion Carbon Black grades also lead the way in purity, economics and reliability.
