Why lithium ion batteries for electric vehicles cars are preferred over lead-acid batteries

Lead-acid batteries have been around for over 150 years; this is a technology used in so many different applications. Lead-acid batteries have their own advantages even though there are disadvantages and many other technologies today, understanding particular technological needs.

Today, lithium batteries have taken over, and they are being used to replace the older technology. Lithium-ion batteries are really attractive for people looking for lighter battery options. Lithium-ion batteries are very light especially compared to lead-acid batteries. Over the years, many improvements have been made on the li-ion batteries to make them even better. There are also different chemistries being used, including lithium polymer, lithium-ion phosphate, and lithium-ion. There are also some other exotic variations available in the market from different manufacturers.

Lifepo4 batteries
Lithium iron phosphate or lifepo4 batteries are a great improvement compared to lead-acid batteries. This is in terms of shelf life, capacity, and weight. This makes them a preferred choice for many and a reliable alternative. The batteries are very safe, and they don’t overheat. This is true even if they get punctured.

The cathode material used to create lifepo4 lithium golf cart battery 48v 100ah is non-hazardous, meaning that there are no ill effects on the environment and health. Oxygen is highly banded to the molecule, and it is highly unlikely that the battery could ignite. Lifepo4 batteries tend to be more stable because of their chemistry. This is why some of the batteries do accept lead-acid configured battery chargers. Lifepo4 batteries tend to be less energy-dense compared to lithium polymer and lithium-ion. Phosphate and iron are cheaper and abundant, so extraction costs are quite reasonable.

Lithium-ion
Lithium-ion batteries are energy-dense compared to other batteries. However, safety is an issue. With the current technology and different security features, most manufacturers are creating 48v lithium-ion golf cart battery packs with BMS.

Lithium cobalt oxide or lico02 is the most common battery option. The oxygen in the chemistry is not very well bonded. If things heat up during discharging and charging or even heavy use, there is a chance of fire.

A battery catching fire can be serious, especially in large applications such as lithium-ion batteries packs for electric vehicles or airplanes. To counter this kind of issue, the best lithium-ion batteries come with BMS. Should overheating occur, the system detects and shuts the power supply to avert any incidence. This ensures that all processes are carefully monitored.

Lead-acid
Lead-acid is much cheaper and has been proven over the years. These batteries are still finding use in many electric car applications as well as starting applications. When lithium-ion batteries are compared to lead-acid batteries, the main disadvantage is the poor performance in low temperatures. However, operating temperatures, weight capacity, and reduction of carbon dioxide are important factors in many applications. Lithium-ion batteries remain superior and are a standard in many industries today.
