Precursor materials

Efficiency and the highest safety levels! These requirements must be met by the battery systems of the future, thus opening up a new market with enormous growth potential. Nevertheless, very few source materials for cathodes actually fulfil these requirements. Lithium iron phosphates are generally considered to be the most suitable material for use in energy storage systems of the future.

Batteries produced with lithium iron phosphate made out of Budenheims precursor materials offer rapid charging and discharging abilities, extended durability and high energy density. Above all, however, and in contrast to other lithium ion chemistries, they offer high intrinsic safety. Even in abuse conditions such as impact, overloading and heat, they prevent the risk of explosion, an especially important factor when used in vehicles and power stations.

Only the highest levels of purity and consistent quality found in Budenheim phosphates, coupled with their nano-scaled, disc-shaped structure with low layer thickness, enable sufficient storage density, high-current capability and rapid, regular charging-discharging cycles. A decisive factor here is keeping contamination levels as low as possible during the production of the cathode material: corrosive ingredients such as sulphate and chloride must be limited, as well as sodium and potassium concentrations, that block the diffusion of lithium ions in the battery therefore greatly diminish efficiency.

The latest high purity and fully automated production plants at Budenheim are the key to producing iron phosphates in top battery quality. Budenheim has the largest production capacity in the world ensuring the safe, sustainable and cost-effective supply of iron phosphates to cathode manufacturers.
