In 2012, Placke et al. first introduced the definition “dual-ion batteries” for the type of batteries and the name is used till today. To note, earlier DIBs typically applied graphite as both electrodes, liquid organic solvents and lithium salts as electrolytes.
Double the fun: Dual-ion batteries (DIBs) have attracted widespread attention due to their unique energy storage mechanism. They are also inexpensive and environmentally friendly, making them a feasible choice for future large-scale energy storage.
Safety is an important parameter for practical applications of batteries, especially for the dual-ion batteries with organic carbonate based electrolytes, as most of them feature a high operating voltage and suffer from the potential safety hazards.
Finally, the prospects and future research directions of DIBs are also presented based on current understandings. The authors declare no conflict of interest. Abstract As a novel cost-effective, high operating voltage, and environmentally friendly energy storage device, the dual-ion battery (DIB) has attracted much attention recently.
Dual-ion batteries (DIBs) based on a different combination of chemistries are emerging-energy storage-systems. Conventional DIBs apply the graphite as both electrodes and a combination of organic solvents and lithium salts as electrolytes.
Among them, dual-ion batteries (DIBs) have been regarded as one of the most appealing alternatives to LIBs with intriguing features of high operating voltage, fast intercalation kinetics, and cost-efficiency [16, 17, 18, 19, 20].
