MSE Supplies, a partner in innovation: Lithium Battery Materials (Article II)

MSE Supplies is a trusted partner globally in helping to enable innovations.  We have supplied materials, equipment, and lab supplies to over 2000 research laboratories and companies worldwide.  We are a U.S. based supplier helping the advancement of research in fields such as materials science, photovoltaics, energy storage, semiconductors, photonics, biomedical research, and basic science research, to name a few. 

In this article, we highlight recent research using our products that have been presented in a peer reviewed journal.

A team of researchers from the USA and China published a paper on a composite solid polymer electrolyte for lithium ion batteries.  In this paper they used three different materials purchased from MSE Supplies, Lithium Nickel Manganese Cobalt Oxide cathode powder (specifically LiNi_0.33Mn_0.33Co_0.33O₂, NMC111), Ta-Doped Lithium Lanthanum Zirconate Garnet powder (Li_6.4La₃Zr_1.4Ta_0.6O₁₂, LLZTO), and Lithium Iron Phosphate cathode powder (LiFePO₄, LFP).

They developed a novel composite solid polymer electrolyte by embedding LLZTO in a mixture of polyvinylidene fluoride and a lithium containing salt.  The composite solid polymer electrolyte (CSPE) showed excellent thermal stability, high room temperature ionic conductivity, and a wide voltage window. Using this CSPE, they constructed a coin cells utilizing NMC111 and LFP cathode powders along with a lithium anode.  These coin cells were stable over 1000 cycles and had an in-situ measured thermally stable window up to 177 °C with a small heat release of 189 J g^-1.  These numbers are far superior and safer to those of standard liquid electrolyte cells (thermal stable window 157 °C and 812 J g^-1).
