With the search for new solutions to energy efficiency and renewable energy problems, our materials are designed for development and manufacture. Whether you work on alternative fuels, solar energy, energy storage, or fuel cells, we offer products to support your advanced technologies that neither deplete natural resources nor harm the environment.
![High Purity Metal Salts Six small piles of high-purity salts, each with a distinct color, neatly arranged in a row against a white background. From left to right, the salts and their corresponding chemical formulas are: 1) Magnesium Chloride (MgCl2): White salt, 2) Calcium Chloride (CaCl2): Pink salt, 3) Manganese(II) Chloride (MnCl2): Off-white salt, 4) Iron(III) Chloride (FeCl3): Orange-brown salt, 5) Nickel(II) Chloride (NiCl2): Green salt, 6) Copper(II) Chloride (CuCl2): Blue salt. Each chemical formula is written in black text below its corresponding pile of salt.](/deepweb/assets/sigmaaldrich/marketing/global/images/categories/biochemistry/high-purity-metal-salts-620x384/high-purity-metal-salts-620x384.jpg)
High-Purity Salts
We provide a broad spectrum of high-purity salts, both anhydrous and hydrated, ranging from 99.9% to 99.999% purity as measured by inductively coupled plasma mass spectrometry (ICP-MS) or inductively coupled plasma optical emission spectrometry (ICP-OES).
Battery Materials
With unrivaled purity and consistency, our battery materials provide excellent, reliable performance to help our customers achieve reproducible data, even during long cycling experiments. Our diverse selection of battery materials supports all your research needs, from bench-scale to pilot-scale and even manufacturing.
