Applications

Electrode coating

Monitor electrode coating uniformity with speed, accuracy, and exceptional defect detection capability

Electrode coatings that are uniform and defect-free play a defining role in delivering reliable batteries of superior quality. Uneven coating of the aluminum or copper substrates compromises characteristics such as charge density, recharge time, and operational lifetime and can lead directly to safety concerns. Detecting defects and non-uniformities early enables cost-effective remedial action and is the key to making better batteries more efficiently. As performance targets rise, battery manufacturers are looking to reliably detect increasingly small defects, intensifying the need for effective in-line measurement.

Thermo Scientific systems for electrode coating weight measurement have a unique source isotope geometry with an extremely high measurement signal and deliver:

an exceptionally high signal-to-noise ratio
precise coating weight measurement
exemplary edge resolution.

Combining advanced sensor, measurement, and reporting capabilities, these systems offer battery manufacturers the market-leading performance required to efficiently detect and remedy defects and non-uniformities prior to cell assembly. This means less waste, less downtime, improved yields, consistent product quality, and minimal risk of failure in the field.

Electrode calendering

Confirm optimal electrode calendering thickness, precisely and repeatably

Calendering ensures consistent compression of the coated electrode, delivering homogeneous thickness and particle size. It helps to control the porosity of the coating, improving electrical contact and adhesiveness, along with other critical parameters. Total electrode thickness measurements are crucial during this final step to avoid excessive compression and deliver electrodes of consistent dimensional accuracy.

Thermo Scientific systems for calendering thickness measurement use the latest confocal technology to measure:

precisely
with unprecedented accuracy and repeatability
and exemplary dimensional resolution.

Combining advanced sensor, measurement, and reporting capabilities, these best-in-class systems offer battery manufacturers the performance required to optimize calendering lines, to improve yield and at the same deliver superior battery quality.

Separator film

Measure multilayer separator film thickness with exemplary resolution

Increasingly sophisticated multilayer separator films are a critical component of high-performance lithium-ion batteries. Separator film properties impact characteristics such as self-discharge rate and safety, providing in-built thermal shutdown and protecting against thermal runaway. Properties ranging from porosity to tensile strength are controlled to deliver desirable performance. Consistent thickness is crucial to optimize battery performance and life, and a primary focus during manufacture.

Thermo Scientific systems for multilayer separator film thickness measure:

a high proportion of the separator film
with unrivalled precision
and exceptional resolution.

Even for complex multilayer designs incorporating, for example, ceramic coatings.

Combining advanced sensor, measurement, and reporting capabilities these systems enable consistent separator film production helping manufacturers to safeguard superior battery quality while at the same time reducing waste and improving process efficiency.
