(De Pere, Wis.) Babcock & Wilcox MEGTEC (B&W MEGTEC) has launched a complete lithium-ion battery electrode manufacturing line in an operating layout that improves flexibility, quality, cost-effectiveness, and speed-to-market.
Matched to meet application-specific production requirements, each line configuration is a complete manufacturing operation, encompassing every stage in the electrode production process, including powder handling, slurry mixing, coating and drying, calendering/roll pressing, secondary drying, slitting, and n-methyl pyrrolidone (NMP) recovery and purification.
“Commercialization of energy storage technology continues to expand with broader applications such as electric vehicles due to advances in battery development,” said Jeff Quass, vice president of technology and development. “Our complete lithium-ion electrode manufacturing line offers a simplified process flow and machinery design, the cornerstone of which is our exclusive simultaneous two-sided coating system. Collectively, the line improves electrode quality and enhances speed-to-market efforts, all with better overall cost-effectiveness.”
The seven process stages of the complete B&W MEGTEC lithium-ion electrode line include:
Additional Features and Benefits
Process Development and Team Training: During the machine build period, B&W MEGTEC provides customer-specific process development trials. This makes it possible to dramatically reduce the time from commissioning to full production by fully training technicians before installation and achieving steady-state production in a shorter timeframe.
Lowering Total Costs: Due to its simplified manufacturing flow and machinery design, the B&W MEGTEC electrode line reduces utility demand, requires fewer technicians/operators, increases yields due to improved quality, features a straight-line product flow and single-level footprint, and requires lower a lower capital investment.
Quality Control: Electrode quality is critical to the viability of lithium-ion battery technology. The B&W MEGTEC electrode line offers a fully integrated data capture and management system that provides complete traceability from raw materials to finished cells. Inline process control improves product quality and confidence, and is based on rheology monitoring, coat-weight measurement at multiple locations, physical quality inspection system, thickness measurement and control, and two-sided coating coupled with flotation drying.
