Battery usage is growing rapidly as new uses are found, leading to the development of new battery types, technologies, and materials. Some commonly-used elements in different types of batteries include lithium, manganese, nickel, phosphorus, and zinc, among others. The percentage of these components can range from single digit up to 30%, depending on the battery.
An important factor in obtaining optimum performance is accurately knowing the ratios of the major components, since deviations can negatively affect battery performance, as can the presence of impurities. Therefore, the major components must be measured both with high accuracy and precision, while, at the same time, measuring impurity levels.
ICP-OES is the ideal analytical technique to meet these needs – it has a high tolerance to matrices, yet is capable of high precision and can accurately measure impurities down to the µg/L level. This work demonstrates the ability of PerkinElmer's Avio® 500 ICP-OES to achieve RSDs < 0.1% for matrix elements in simulated battery materials, the result of the instrument's ability to perform true simultaneous measurements.
