Are lithium-ion batteries suitable for EVs?

Why do lithium batteries fail?

In addition to lithium-induced battery failure, the cycle life is another problem. For instance, the use of lithium as an anode causes dendrite growth and pulverization during cycling, thereby significantly reducing the life of the cell. The large volume change in a cell with a lithium anode is also an unsolved problem.

What happens if a lithium ion battery is overheated?

In LIB, both lithium coating and overheating reduce the cycle life of the battery. The charge cut-off voltage of LIB is generally 4.2 V . Charge voltage above this value reduces the capacity and lifetime of the battery and causes safety vulnerability.

What is the future of electromobility based on lithium ion batteries?

It is known that Honda and Toyota have been producing hybrid vehicles using Ni-MH. Future of electromobility will be dependent on the lithium ion batteries. Although the lead acid, NiMH and NiCd batteries are available for several applications, the lithium ion technology has prevailed in the competition because of many advantages.
