Challenges associated with lithium dendrite growth and the formation of dead lithium significantly limit the achievable energy density of lithium metal batteries (LMBs), particularly under high operating current densities. Our innovative design employs a state-of-the-art 2500 separator featuring a meticulously engineered cellulose acetate (CA
Initially, separators were basic polymer films designed for lithium-ion batteries, focusing primarily on preventing short-circuits and allowing ionic conductivity [, , ]. As the field progressed, researchers began addressing the specific challenges of LMBs such as dendrite formation and chemical reactivity [13, 14].
One promising approach involves the strategic use of separators to regulate and optimize Li + distribution during battery operation. These separators serve as critical components that not only physically isolate the electrodes but also influence the pathway and efficiency of Li + migration between them.
As a result, the CA@2500 separator could achieve uniform deposition and protect the lithium cathode theoretically. Conversely, the original 2500 separator became susceptible to nonuniform lithium deposition, and it subsequently gave rise to uncontrolled lithium dendrites.
To enhance the thermal stability of lithium-ion batteries (LIBs) , a novel ceramic-coated separator has been developed by integrating one-dimensional silica tubes (ST) onto one side of a commercial polyethylene (PE) porous separator (Fig. 5 b).
Deposited lithium metal can penetrate the separator in dendritic or invasive forms, causing separator failure and consequent internal short-circuits, posing a serious threat to battery safety . Fig. 2. The failure mechanism of separators in Li battery. (a) The failure mechanisms of separators in lithium-metal batteries.
Over time, the battery with 2500 separators showed obvious polarization. This phenomenon was caused by the continuous loss of electrolyte and the formation of lithium dendrites . Hence, the CA@2500 separator enabled stable lithium plating and stripping by regulating ion transport in proximity to the lithium metal.
