Efficient polysulfides interception/conversion ability and rapid lithium-ion conduction enabled by MOFs modified layers are demonstrated in Li–S batteries. In this perspective, the objective is to present an overview of recent advancements in utilizing pristine MOF materials as modification layers for separators in Li–S batteries.
In this scenario, lithium-sulfur (Li-S) batteries are considered a ground-breaking technology because they have five times the theoretical specific capacity (1675 mAh g –1) of LiBs with high specific energy density (2600 Wh kg –1).
The Li−O 2 batteries assembled with the Li@Super P anode and LiI additive could mitigate the detrimental shuttling effect of I 3− and deliver a high reversible capacity of 1000 mAh g −1 with a median charge voltage lower than 3.3 V after 50 cycles.
Although there are plenty of merits for lithium–sulfur (Li–S) batteries, their undesired shuttle effect and insulated nature are hindering the practical applications. Here, a conductive metal–organ...
Abstract Severe polysulfide dissolution and shuttling are the main challenges that plague the long cycle life and capacity retention of lithium-sulfur (Li-S) batteries. To address these challenges,...
The utilization of MOF materials to modify Li–S battery separators has achieved substantial attention from researchers in recent years. Nonetheless, challenges such as the notorious shuttling effects and low sulfur utilization require modified separators that can effectively mitigate these issues and expedite polysulfides conversion.
