Influence of PESU/PVP based nanofibrous separators on the properties of LNMO cathode based Li-ion batteries

Key Points

• The aim is to investigate the effects of PESU/PVP based nanofibrous separators on lithium-ion battery stability.
• Utilized PESU/PVP electrospinning to create nanofibrous separators.
• Evaluated the performance of LNMO cathodes in cells with these separators at operating voltages over 5 V.
• Cells with PESU/PVP separators show improved stability compared to conventional separators.
• LNMO cathodes demonstrate better performance metrics when paired with the new separators.
