Product Information

Electrolyte solutions used in lithium-ion batteries are analyzed utilizing an automated system (prepFAST IC) in combination with an ICPMS to determine accurate and precise amounts of Li salts and stabilizing agents. Liquid electrolytes are one of the main components that are used in Lithium-ion batteries. The electrolyte allows positively charged ions (typically Li ions) to move between the cathode and anode, and plays a crucial role in battery performance and lifespan. There are three components that make up the electrolyte: Li salt (e.g., LiPF₆), organic solvent (ethylene carbonate), and a stabilizing additive (e.g., LiPO₂F₂). Some of the common Li salts are LiPF₆, LiBF₄, and LiClO₄. This work will focus on a quick and easy analytical method for determining which Li salts (or Li species) and additives are present in each electrolyte.

Battery cathode materials are pressed into pellets and analyzed by laser ablation ICPOES (LA-ICP). Simplification of the sample preparation not only eliminates the need for the time-consuming, hazardous acid digestion steps, but also decreases the time from sample receipt to result to <5 minutes.

Laser-induced breakdown spectroscopy (LIBS) was used to investigate the elemental distribution within the solid-electrolyte interphase (SEI) of the lithium-ion batteries. Four different anodes were analyzed in this study, these were a pristine, 3.6V, 3.6V without fluoroethylene carbonate (FEC), and 4.8V. Each battery was cycled (charge/discharge) three times each.

Digested cathode powders were analyzed with the prepFAST MX+ connected to an Avio 500. This setup, powered by Xceleri software, allows for an automated standard addition method that provides more accurate results, less sample preparation, and reduced acid waste.

The DispensingStation is a user-friendly and approachable automation system equipped with a touchscreen controller and an ultrasonic sensor designed for precise laboratory sample preparation. This innovative system streamlines and automates processes such as sample dilution, offering customizable methods to suit your needs. By simplifying these tasks, the DispensingStation enhances the accuracy of results while saving labs significant time and money. To demonstrate the capabilities of the DispensingStation, experiments were designed based on acid digestion. Acid digestion is commonly used for analyzing solidstate samples like soil and metals. However, the resulting matrix often requires dilution for ICPMS analysis due to its high solid fraction. The heated digestion process yields varying initial volumes, posing challenges for maintaining consistent final volumes during dilution. The DispensingStation solves this problem by using an ultrasonic sensor which provides precise filling of v

Critical sample data, including barcode ID, is exported to a LIMS system or ICPMS software to automatically generate a sample run list with minimal user intervention.
