Lead Acid and Lithium Ion Batteries in Electric Automobiles
Lead Acid batteries
Lead acid batteries are the leading element for the electric automobile market today. The purpose is clear: their ability to provide the high surge currents needed for an automobile's starter motor tends to make them a dependable power source at an cost-effective price. For the energy necessary to run an electric automobile, the common vehicle usually has 8-12 kWh lead acid batteries installed, so price tag is really a considerable consideration. Their ease of installation tends to make them that considerably far more desirable as a energy supply.
The disadvantage is their short lifespan of only three years, at which point they could no longer be recharged and should be disposed of. Nonetheless, this simple technologies is cheap and very easily manufactured. Lead acid batteries use a high level of reused materials. Flat or disposed batteries are recycled into new batteries, maintaining the carbon footprint low around the lead acid utilized inside the subsequent batch of batteries and providing about 15 kg CO2 together with the typical l kWh lead acid battery.
The worth of raw materials has spiked up the recycling market for recycled lead acid batteries after they are disposed of. Nearly all of the elements of a lead acid battery are recyclable - 97 percent. The battery case is created of polypropylene; the plates are made of lead, with water and acid mixed as an electrolyte. The casing and plates can be simply melted down and reformed, since lead's melting point is low. In this way, small power is needed to convert melted bring about the needed raw material for reuse.
This ability to preserve fees down by reusing materials tends to make recycling desirable and easily doable. Europe recycles one hundred percent lead acid batteries, whilst the U.S. boasts a 98 % recycling rate.
If an electric vehicle with eight lead acid batteries have been replaced once in three years, the batteries' carbon footprint over the vehicle's lifetime could be:
Estimated carbon footprint per battery: 15 kg
Estimated carbon footprint per battery pack (8 batteries): 120 kg
Estimated quantity of battery packs needed throughout the vehicle's lifetime: 4
Carbon footprint more than automobile lifetime: 480 kg
C02/km more than 50,000 miles (80,000km): 6g
Such configuration could be found in REVA i (G-Wiz), Aixam Mega City, as well as the NEVs (Neighborhood Electric Automobiles).
Lithium Ion
Lithium ion batteries possess a longer life than lead acid batteries, using a 5-7 year lifespan. There are some automobile producers and car owners who favor to make use of this higher and more pricey battery technology, that are in some instances made to last the vehicle's lifetime.
To manufacture a lithium ion battery for an electric automobile, the carbon cost is about 22 kg per kWh energy storage. Most tiny electric automobiles are outfitted with 12-16 kWh lithium ion batteries. The carbon footprint is about 264-352 kg per automobile.
At the end of their lifespan, the metals from lithium ion batteries can be extracted. Nonetheless, only 50 percent on the batteries' components can currently be reused to make new batteries. Hopefully, with technological advancements, this figure will rise to 95 percent recyclability by 2015.
Calculations show that recycled lithium ion batteries possess a manufacturing carbon footprint of six.8 kg per kWh energy shop.
Estimated carbon footprint to get a 12 kWh battery pack: 220 kg
Carbon footprint more than lifetime of vehicle: 440 kg
C02/km according to 100,000 miles (160,000 km) 3g
