Battery whole process control specification

Why should a battery weighing system be integrated with in-line weighing controls?

Embedding weighing steps strategically along your battery production can detect missing components, ensure accurate dispensing, and enable perfect assembly of all systems, from stacking to module assembly. In-line weighing controls identify deviations right when they happen, with high precision, allowing checking of 100% of products.

Do slurry components affect the quality of battery cells?

Even small deviations in the composition of slurry components can alter the shelf life and the quality of the battery cells, possibly damaging the cell modules and packs latterly, after their integration in the OEM. Sartorius engineers weigh cells as solutions for integration of a force or weighing sensor into production lines.

How does particle shape affect battery performance?

Particle shape afects slurry rheology as well as the electrode coating in terms of packing density, porosity and uniformity. To achieve the highest level of battery performance, manufacturers must also understand and optimize the particle morphology.

What makes a good battery component manufacturer?

Battery component manufacturers must not only deliver consistent overall quality – they must deliver it throughout the manufacturing process. The continuity of the manufacturing process means errors or impurities at an early stage will accumulate, resulting in much larger consequences further down the production line.

Why is quality important in battery manufacturing?

Quality needs to be monitored at every stage – from raw materials through to cell assembly – to maintain production eficiency and minimize waste. Likewise, research into new battery materials must ascertain all the critical parameters that could afect battery performance throughout the entire manufacturing process.

How to predict the deformation and stresses in a battery separator?

To predict the deformation and stresses in the separator in battery cells, it is necessary to measure the expansion/shrinkage behavior. This is achieved by Thermomechanical Analysis (TMA), expressed by the coeficient of thermal expansion (CTE).
