3. DendriteLMBs were used in the 1970s but were soon discarded owing to the ramified and branched morphology of Li deposition, called dendrites, in liquid electrolytes, which caused short-circuiting of the cell and posed a safety hazard [18,47,48]. Dendritic formation becomes more severe at high current densities and during long-term cycle operations. Therefore, efforts should be made to suppress and eliminate dendrite formation during Li plating and stripping.

AbstractNovel two-dimensional semiconductor crystals can exhibit diverse physical properties beyond their inherent semiconducting attributes, making their pursuit paramount. Memristive properties, as exemplars of these attributes, are predominantly manifested in wide-bandgap materials. However, simultaneously harnessing semiconductor properties alongside memristive characteristics to produce memtransistors is challenging.
