To develop and evaluate a renewable, highly thermal-resistant cellulose-based composite nonwoven as an advanced separator for lithium-ion batteries.
Fabricated nanofibrous cellulose-based composite nonwovens using an electrospinning technique followed by a dip-coating process.
Characterized physical properties including electrolyte wettability, thermal tolerance, and ionic conductivity.
Tested electrochemical performance, specifically rate capability and capacity retention, in comparison with standard commercial polypropylene separators.
The cellulose composite nonwoven demonstrated superior heat tolerance, improved electrolyte wettability, and higher ionic conductivity compared to polypropylene separators.
Battery cells assembled with the composite nonwoven exhibited superior rate capability and enhanced capacity retention over commercial polypropylene counterparts under identical operating conditions.
