A Review on Inorganic Nanoparticles Modified Composite Membranes for LIBs
Separators with high porosity, mechanical robustness, high ion conductivity, thin structure,
excellent thermal stability, high electrolyte uptake and high retention capacity is today’s burning
research topic. These characteristics are not easily achieved by using single polymer separators.
Inorganic nanoparticle use is one of the eorts to achieve these attributes and it has taken its place
in recent research. The inorganic nanoparticles not only improve the physical characteristics of
the separator but also keep it from dendrite problems, which enhance its shelf life. In this article,
use of inorganic particles for lithium-ion battery membrane modification is discussed in detail
and composite membranes with three main types including inorganic particle-coated composite
membranes, inorganic particle-filled composite membranes and inorganic particle-filled non-woven
mates are described. The possible advantages of inorganic particles application on membrane
morphology, dierent techniques and modification methods for improving particle performance
in the composite membrane, future prospects and better applications of ceramic nanoparticles and
improvements in these composite membranes are also highlighted. In short, the contents of this review
provide a fruitful source for further study and the development of new lithium-ion battery membranes
with improved mechanical stability, chemical inertness and better electrochemical properties.
