Identifier B1

The large surface area of nanofibers and nanoplatelets can increase the storage capacity and reduce the weight of batteries and capacitors, making them ideal materials for the battery industry.

The demand for electrical mobility and off-grid solar power are among some of the drivers for the massive growth in the use of nanomaterials in those industries.

Potential exposure is possible in different life cycle stages, from development and testing to cell production and manufacturing and finally, in recycling.

Nobody wants to subject their employees to exposure to dangerous materials, so it’s essential to monitor exposure when they are used.  Stat Peel’s Identifier can detect airborne particles involved in battery production and recycling. Carbon nanotubes, for example, are increasingly being used in anodes and cathodes because their properties improve battery performance and lifespan.

The Identifier can easily detect airborne CNTs and metal oxides, some of which are highly toxic. The alphabet soup of current battery materials includes NCA (lithium nickel cobalt aluminum oxides), NMC (lithium nickel manganese cobalt oxides) and LiFePO4 (or LFP for lithium iron phosphate), among others. Engineering controls are an obvious requirement when working with these materials, and monitoring for airborne particles provides a method for accurately detecting release and personal exposure.

Personal and Stationary Monitoring

At Stat Peel, we have developed a compact badge sensor and an integrated bench-top sized optical reader to monitor personal occupational exposure to nanocellulose fibers. It works in two steps:

1. The employees wear lightweight badges during their workday. The badge collects the respirable fraction of airborne nanocellulose fibers using an inertia-based size separator on a custom functionalized membrane.

2. At the end of a shift the badges are inserted into the reader, which selectively detects nanocellulose fibers using the most advanced Raman spectroscopy and reports and stores personal exposure.

Comprehensive Facility Monitoring

With a software upgrade our system can be used to monitor contamination sources across the whole manufacturing area.


The badge

Badges can be worn by employees to monitor personal exposure, as well as placed in specific locations within a facility to monitor release. Each badge is about the size and weight of a phone, so it is easy to wear throughout the workday. There is a small opening that allows air to flow through to the filtration slide.

Filtration slides

Filtration slides with specially developed membranes are used to gather particles from the filtered air. Each slide has one, two or three membranes to collect the respirable particle fraction. The appropriate number of membranes is determined by how “clean” a facility is. Each slide has a barcode so it can be traced to a certain user, and the slides can be archived to provide an additional record of compliance.
