6 FAQs about [Lithium battery without membrane]

Do membrane-free batteries need a membrane?

Recently, immiscible electrolyte-based liquid–liquid biphasic systems have received significant attention for the construction of membrane-free batteries. The liquid–liquid interface of these biphasic systems separates the catholyte and anolyte and functions as a natural barrier, thus eliminating the need for a membrane.

How does a lithium dendrite membrane work?

The membrane functions as a barrier between the cathode and anode, and the detection and elimination of lithium dendrites can be achieved through innovative design in the composition and structure of the membrane. This involves the utilization of metals capable of reacting with lithium dendrites, and incorporation of other visual indicators.

Should a Lithium-Ion Separator be considered a functional membrane?

Converting the chemically inert separators into functional membranes could be an effective way to alleviate these issues. The separators can function more in lithium-ion batteries via the rational design of polymer structure. In this sense, the separator should henceforth be considered as a functional membrane in lithium-ion batteries.

Can lithium dendrites be detected before a battery fails?

The current challenge lies in detecting the growth of the lithium dendrites before a battery fails. Considering that before the battery shorts out, the lithium dendrites must first reach the membrane. Therefore, detecting the interaction of the dendrites with the separator can function as an alert to detect the growth of lithium dendrites.

Why are lithium dendrites a problem in a battery separator?
