Lithium Batteries Features


The first commercial Li batteries were marketed in the 1970s. For cost reasons, their market share lags behind that of aqueous primary batteries. Yet, in some applications, that is those requiring long operation/storage times, extreme temperatures or high power, these are the batteries of choice. The basic characteristics making primary Li batteries suitable for many applications are:

• High energy (over 200 Wh/kg and 400 Wh/L)

• High and flat potential

• High power (in spirally wound configurations)

• Long shelf life, with capacity losses of 1% per year at room temperature

• Wide temperature range

• Construction in several form factors (coin, cylindrical, prismatic and very thin batteries) and with capacities ranging from a few mAh to several Ah.
