Are low current rechargeable batteries durable

Are low-temperature electrolytes suitable for rechargeable batteries?

The 40 years development of low-temperature electrolytes for rechargeable batteries has been reviewed. Critical insights are given from both underlying mechanistic and practical engineering aspects while we traverse the history on the rational design of low-temperature electrolyte systems.

How to design a low-temperature rechargeable battery?

Briefly, the key for the electrolyte design of low-temperature rechargeable batteries is to balance the interactions of various species in the solution, the ultimate preference is a mixed solvent with low viscosity, low freezing point, high salt solubility, and low desolvation barrier.

Why are rechargeable batteries important?

Rechargeable batteries have been indispensable for various portable devices, electric vehicles, and energy storage stations. The operation of rechargeable batteries at low temperatures has been challenging due to increasing electrolyte viscosity and rising electrode resistance, which lead to sluggish ion transfer and large voltage hysteresis.

Is EC suitable for low-temperature batteries?

As a common constituent of commercial electrolytes, the physical and chemical properties of EC render it unsuitable for batteries working in low-temperature environments. The development of electrolytes with low content or even no EC is essentially necessary.

What are the different types of rechargeable batteries?

Rechargeable batteries are categorized into types such as proton, lithium-ion, zinc-ion, sodium-ion, etc., which are based on the primary carriers present in their electrolytes. For different battery systems, the mechanisms and performances of antifreeze electrolytes are slightly different.

Can cathode materials improve low temperature performance of rechargeable batteries?

Compared with the anode materials at low-temperature, cathode materials have been less studied. Recent studies have revealed that size reduction, functional coating, and element doping are favorable strategies to enhance the low temperature performance of rechargeable batteries.
