Progress in determining the safety of traction batteries for electric vehicles

Abstract

Rechargeable Lithium-ion batteries are electrochemical storage components characterized by long cyclic and calendar lifetimes, high gravimetric and volumetric energy densities and high energy efficiency. Their price has fallen significantly in recent years. This lowered the price of traction batteries. For the use of lithium-ion batteries in the drive train of electric and hybrid vehicles, high growth rates are predicted for the next 15 years, the presence of electric cars on the road will increase significantly. Therefore the present safety consideration is limited to lithium-ion batteries.
