Functional membranes play different roles in battery systems. For example, compared to a conventional lithium-ion battery membrane, ideal membranes for the Li-S battery should also have the function to block the shuttling of polysulfide and prevent the internal short circuits.
Overall, persistent challenges pertaining to the unsatisfactory thermal stability of lithium battery separator membranes, insufficient shutdown functionality, and suboptimal ion conductivity present pressing areas of inquiry that necessitate meticulous analysis and dedicated investigation.
Toray Creates Membrane Separators to Recover Lithium from Used Lithium-Ion Batteries A new highly lithium-selective nanofiltration membrane vastly improves acid resistance. Toray Creates Membrane Separators to Recover Lithium from Used Lithium-Ion Batteries A new highly lithium-selective nanofiltration membrane vastly improves acid resistance.
Provided by the Springer Nature SharedIt content-sharing initiative Cation separation under extreme pH is crucial for lithium recovery from spent batteries, but conventional polyamide membranes suffer from pH-induced hydrolysis. Preparation of high performance nanofiltration membranes with excellent pH-resistance remains a challenge.
Similar to his previous work, lithium-symmetric batteries assembled by the prepared PBI separator also had good lithium deposition/stripping performance under high current density, and the pores with nano-size structures can significantly inhibit the growth of lithium dendrites (as shown in Fig. 17 a and b).
Furthermore, although the porous feature of the membrane meets the requirement of traditional lithium-ion batteries, it cannot inhibit the shuttle of polysulfide in lithium-sulfur batteries.
