Dalhousie team reports ternary blends of electrolyte additives greatly enhance performance of NMC Li-ion cells 30 March 2015 Batteries for electrified vehicles require much longer calendar and cycle lifetimes, as well as improved high temperature tolerance, than their portable consumer electronics counterparts. Electrolyte additives can be used to extend cell lifetime by suppressing parasitic reactions between charged electrodes and electrolyte by modifying the solid electrolyte interphase (SEI) at the negative electrode or the passivation layer formed on the positive electrode. Researchers at Dalhousie University (Canada) led by Dr. Jeff Dahn now report that Li[Ni1/3 Mn1/3 Co1/3 ]O2 (NMC111)/graphite and Li[Ni0.42 Mn0.42 Co0.16 ]O2 (NMC442)/graphite pouch cells demonstrate greatly enhanced performance when ternary blends of electrolyte additives are added to the cells.
