100g Conductive Expanded Graphite (TIMCAL Timrex® BNB90) Powder for Battery Research and Polymer Additive
Conductive Expanded Graphite (TIMCAL Timrex® BNB90) Powder for Battery Research and as a Polymer Additive
Electrolytic manganese dioxide (EMD) is the critical component of the cathode material in modern alkaline, lithium, and sodium batteries including electrochemical capacitors and hydrogen production. TIMCAL Timrex BNB90 is the premium high aspect ratio graphite designed for EMD cathodes with low graphite content. Timrex BNB90 high aspect ratio graphite, characterized by its unique texture and morphology, is designed for cathodes with low graphite content. Manufactured with unique and sophisticated process which results in a two-dimensional particle shape that ensures very high electrical conductivity in the cathode mix with a very low percolation threshold and strong mechanical stability at low loadings.
TIMREX BNB 90 Graphite shows very high electrical and thermal conductivity even at a relatively low graphite content. It is suitable for elastomers and seals. TIMREX BNB 90 Graphite consists of irregular strong anisometric particles. It is recommended for automotive (micro HEV, e-bikes), energy storage and industrial (fork-lifts, back-up systems & medical devices). It provides good wettability, high affinity, sufficient BET specific surface area (SSA) and double layer capacitance for dynamic charge acceptance (capacitor effect). It offers sufficient purity to reduce gassing and self-discharge, balanced particle size distribution for homogeneous incorporation into electrode structure, improved cycle life and improved charge acceptance.
