Lab Equipment, Integrated Weighing Solutions to Support Battery Manufacturing
Material refiners, battery manufacturers, OEMs and recyclers are all invested in meeting global carbon neutrality goals and developing the super battery. Developing safe, durable rechargeable batteries that satisfy “green” mobility initiatives requires significant investment in research and development (R&D) and quality control (QC), as well as expertise in production stages.
Sartorius provides solutions for several steps of the rechargeable battery manufacturing process - from material purity determination and in-process optimization to final release - with intuitive lab tools and integrated weighing solutions, further enhanced by multivariate data analytics.

Frequently Asked Questions
Battery production is subject to many constraints:
- Ecological - Carbon neutrality objective
- Economic - Reaching parity price for EV manufacturers
- Political - No geopolitical dependence
- Transport - Safety or disruption of the supply chain
- Technological - New chemistries and increased energy density
These challenges can be overcome by building successful local partnerships across the supply chain, from active materials to manufacturing, vehicle assembly and recycling.
In simple terms, lithium-ion rechargeable batteries are made of two electrodes, a separator and filled with electrolyte. The technology is constantly evolving to increase safety and evergreen energy density.
- Cathode: A mixture of active materials such as lithium metal oxides (NMC, LFP, LMO, LCO), conductive additives and binders (SBR, PVDF) coated precisely on an aluminum collector
- Anode: The materials commonly used are based on carbon (graphite), lithium alloyed metals and binders coated in a thin layer on a copper collector
- Electrolyte: It combines polymer or water-based solvents and lithium salts
- Separator: Typically, multilayer sheets made of PE or PP polyolefins, offering a compromise between excellent mechanical strength and sufficient porosity to facilitate ionic exchanges in the cell
Lithium reacts with moisture in the air to create lithium hydroxide and hydrogen. This not only reduces the capacity of the battery and number of cycles, but also affects the structural stability of positive and negative materials. For this reason, manufacturers work in controlled environments - like a dry room - to allow for strict monitoring of water content during the LIB manufacturing process.
Grammage is the weight of the electrochemically active material per unit area of the current collector. It is defined by the thickness of the electrode coating and is usually represented in mg/cm². The grammage influences capacity and cycling behavior.
