Lithium-ion Battery in Cold Countries

  • While batteries can operate in relatively cold climates, they have their limits.

  • Lithium-ion batteries only have about 12% of their room temperature capacity.

  • This temperature is limited in cold countries ,where temperatures can be lower than -50 degrees Celsius.

Limitations in Lithium-ion Battery:

  • The Electrolyte  and Electrodes have great influence on battery  performance.

  • Ester based  conventional electrolytes(Lithium-ion battery) use sluggish conductors and electrochemical reactions.

  • So they don’t hold up too well  in cold countries.

Recent Research:

Electrolyte:

  •  Ester (ethyl acetate)-based electrolyte has a low freezing point that enables it to conduct a charge even at extremely low temperatures.

Electrodes used:

  • Polytriphenylamine (PTPAn) cathode

  • 1,4,5,8-Naphthalenetetracarboxylic Dianhydride (NTCDA)-derived Polyimide (PNTCDA) anode.

Advantages of electrodes:

  • Don’t rely on intercalation—(the process of continuously integrating ions into their molecular matrix, which slows down as the temperature drops.)

  • Can work  well at ultra low temperatures.

  • Inexpensive,Environment friendly.

  • Though it has low specific energy, it provides the most promising potential in special field applications.

Improvements needed:

  • Require some tweaking

  • Should increase the specific energy
