Colloidal soft matters-based flexible energy storage devices:
Here, we systematically review the design strategies of colloidal soft matter-based energy storage devices, covering the optimization of key components such as electrolytes and
The energy density of a battery is important and compared with traditional lead-acid batteries, the energy density of colloidal batteries has been greatly improved, reaching about 100Wh/kg, with a cycle life of 800-1500 times, and safer to use.
The most important features of colloidal lead-acid batteries are: the discharge curve is flat, the inflection point is high, the specific energy, especially the specific power, is more than 20% larger than that of ordinary lead-acid batteries, and the service life is generally about twice as long as that of ordinary lead-acid batteries.
Under the same sulfuric acid purity and water quality, the storage time of colloidal lead-acid batteries can be extended by more than 2 times. It can be stored for two years and can be used without charging, and the capacity of the 2V series remains above 99.9% after standing for two months.
Benefited from the development of colloidal soft materials-based electrolytes and electrode materials, the electrochemical performance of energy storage devices has been greatly improved.
