Battery Technology

Batteries are the main influence in the development of electric vehicles.

The only battery BIthat is commercially viable at high volume is still the lead-acid type.

Numerous companies are working on alternative types of battery, trying to make the breakthrough that will allow the electric vehicle to compete realistically with the internal combustion engined vehicles. This basically means the charging of batteries and the range vehicles can cover between charges.

The most popular types of battery are:

§ Lead Acid

§ Nickel Cadmium

§ Nickel Metal Hydride

§ Sodium Nickel chloride

§ Lithium Polymer

Battery Other battery types include:

ª Nickel Iron

ª Nickel Zinc

ª Sodium Sulphur

ª Lithium Iron Sulphide

ª Zinc Air

ª Zinc Bromide

Something Different

ª Vanadium These batteries are different as they can be recharged by replacing the electrolyte.

Something New

Lithium Sulphur battery has promise of high energy density.

All of these different battery types have different specifications and offer various levels of performance. The table compares some of their characteristics and states at what stage of development they are at in terms of production availability.
