However, the inherently limited capacity and unsatisfactory rate capability of graphite will decrease the energy density and power capability. Meanwhile, resulting from the intercalation reaction mechanism, the exfoliation of carbon layer will influence the lifespan and restrict the development and application of DIBs in the field of energy storage system [ 14, 15 ].
Among these alternatives, the advantages of DIBs (some common to the other battery chemistries) are: 1) eliminating lithium and critical elements such as nickel and

Thus far, lithium-free graphite dual-ion batteries have employed moderately concentrated electrolyte solutions (0.3–1 M), resulting in rather low cell-level energy densities of 20–70 Wh kg −1.
This battery exhibits a cell-level energy density of 207 Wh kg −1, owing to the high weight content of the electroactive species (65 wt%) in the electrolyte [5 M solution of potassium bis (fluorosulfonyl)imide), KFSI, in alkylcarbonates] and a high operation voltage of 4.7 V.
A K-based dual graphite dual ion battery is assembled using this high concentration electrolyte. The battery achieves a discharge medium voltage of ∼4.24 V and delivers a specific capacity of 94.2 mAh g −1 at a current density of 100 mA g −1. After 100 cycles under test conditions, it retains ∼92.3 % of its initial capacity.
As in any battery, the energy density of a DIB depends on the voltage and capacity, both parameters being determined by anion hosting materials. A graphite cathode can deliver a discharge capacity of around 100 mAh g −1 and a high working voltage beyond 4.5 V with LiPF 6 in EMC as an electrolyte.
Owing to anion intercalation, DIBs can achieve high rate performance and fast charging ability. Taking dual graphite batteries with LiPF 6 salt in ethyl carbonate (EC)–dimethyl carbonate (DMC) electrolyte as an example, Li + ions are solvated in the electrolyte, whereas PF 6− is less solvated in the organic electrolyte because of its large size.
