Mixing Equipment for UKBIC Flexible Industrialisation Line (FIL)

Vendors will be invited to submit a bid to provide a flexible mixing system to fit into a clean and dryroom. This system would need to be representative and scale-able to a larger system For the mixing process of the anode and cathode materials to form a coatable electrode slurry, the necessary equipment must be procured; In the first step, the materials (liquids and solids) of the electrode slurries must be dosed to the mixing system from storage containers. The materials are subdivided into active materials (e.g. graphite, lithium metal oxide etc. – typically in the form of micron scale powders), conductive agent, binder, additives, solvents etc. The target of the process is the production of a homogeneous electrode coatable slurry. Agglomerates or contamination of the slurry with foreign particles (especially metallic particles, air bubbles) must be excluded. Mixing is precursor step for coating and drying. The supplier must ensure that his system can be linked to the coating and drying line, or that slurry can be transferred to the coater. • The mixer must be capable of both Anode and Cathode slurries, therefore the supplier must provide a thorough cleaning strategy for the system. • Vendors are invited to submit equipment solutions to provide a mixing capability for minimum 25L to 70L per batch, mixing can be a batch or comparable continuous process. • The equipment needs to operate between ambient conditions to -70°C dewpoint. • The mixing equipment must be capable of producing homogenous, gas free electrode slurries suitable for slot-die coating on conventional coating and drying equipment. • The mixing system must have the capability for inerting and provision of dry nitrogen or dry argon blanketing or vacuum system. • The equipment must offer modular solution, so equipment can be easily reconfigured or decommissioned in the future. • The equipment must be capable of producing different recipes and formulations and mixing protocols. One mixing system must be procured – if budget allows, a second mixing system may be procured to avoid cross-contamination. The potential bidders are encouraged to provide information and suggest what savings could be made if a second mixing system was ordered at the same time as the first. Bidders are encouraged to put forward space or energy efficient next generation mixing processes applicable to battery slurries. All equipment to provide UKCA conformity.
