As new, ever more energy-dense battery materials are being developed, it is becoming increasingly challenging for electrolytes to cater both requirements set by the anode and cathode. Ethylene carbonate plays a key role in forming stable solid-electrolyte-interphase on graphite anodes, but combination with nickel-rich cathodes, such as LiNi0.8Mn0.1Co0.1O2 (NMC811), leads excessive cathode oxygen loss at high voltage. In this work, study proposes cell design, where different compartmentalized An ionically conductive polymer electrolyte membrane used prevent two from mixing. NMC811 versus full cells using achieved capacity retention of 85.1% over 520 cycles compared 61.7% control systems standard under same conditions. addition, shown that show less transition metal cross-over impedance build-up during cycling. Overall, design proposed work allows independently optimize holds promise better support diverging next-generation anodes cathodes.

The [solvent-Li+] complex in poly(vinylidene fluoride) (PVDF)-based polymer electrolytes enables fast ion conduction but also makes it difficult to be compatible with high-voltage cathodes. Here, we demonstrate that the residual amount of solvent significantly affects transport properties and interfacial stability electrolyte. In LiNixCoyMnzO2/Li batteries, a nonuniform unstable double-layer CEI is formed due decomposition desolvated NMP molecules lithium salts, resulting aggravated polarization rapid capacity decay. Thus, difluorophosphate (LDFP) introduced as sacrificial additive into composite cathode construct situ robust protective layer. Computational experimental results indicate its strong adsorption on NCM surface helps form uniform inorganic-rich interface passivate catalytic sites NCM, thereby achieving stable long-term cycling solid-state batteries.
