Rechargeable lithium metal batteries are considered as one of the most promising next-generation battery technologies because of the low density (0.534 g cm −3) and high gravimetric capacity (3680 mAh g −1) of lithium metal. 1–3 However, lithium is reactive in almost all liquid electrolytes, producing a passivation layer known as the solid
When the battery is being charged, lithium ions move from the cathode, through the electrolyte, and embed themselves in the anode. This process is known as intercalation. During discharge, these ions make the opposite journey, traveling from the anode to the cathode, generating an electric current that powers the connected device.
Here, we combine a solvate ionic liquid with a disproportionation-based electrolyte, aiming for lithium battery application. Indeed, a positive cooperative behaviour is found to generate free Li + cations, which together with a smooth and flexible coordination leads to increased ion mobility.
Li+ battery chargers come in three types: switch-mode, linear, and pulse. The major difference between these topologies is the size and cost vs. performance tradeoff they offer. Switch-mode chargers tend to be larger and more complex and require a large passive output LC filter; the extra board space buys added efficiency.
