Types of batteries used in electric cars and best ev battery technology in 2022. There are different types of batteries used in electric cars. Lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, and ultracapacitors are the four main types of batteries used in electric cars. Now the question is what batteries do electric cars use for best performance. First understand the types of batteries used in electric vehicles. Similarly the materials used to make electric car batteries. Little more on Which electric vehicle battery technology will be adopted in future.
Types of Batteries Used in Electric Vehicles:
- Lithium-ion batteries
- Nickel-metal hydride batteries
- Lead-acid batteries
- Solid state batteries
- Na – β alumina batteries (Na-S and Na-NiCl2)
Lead-acid batteries (Types of Batteries):
Despite their low cost (100-150 $/kWh), lead-acid batteries have a low specific energy (30-50 Wh/kg), making them unsuitable for most electric road transport vehicles (e.g. fork lifts) (even HEVs). It also has a short lifespan (3–5 years). With smaller intermediate storage batteries than competing battery technologies or modern, compact, and lighter capacitor banks/supercapacitors, lead-acid battery manufacturers may be able to significantly join the micro-hybrid automobile market. Medium-term growth of micro-hybridization for tiny cars is at stake (5-10 years).
Nickel-metal hydride batteries:
NiMHs’ specific energy (100 Wh/kg) does not meet the requirements for fully electric vehicles, they are primarily used in hybrid vehicles (HEVs and PHEVs) with limited storage capacity, rather than fully electric vehicles. NiMH on-board storage capacity for plug-in hybrid vehicles (PHEVs) reached 30 kilometers. The availability of rare earths and nickel in both the anode and cathode of these batteries is a concern. The high Ni content and, most likely, rising Ni costs limit the opportunities for further cost reduction and, consequently, use in future electric vehicles (EV). As this opinion is by “Zoran Stević”
Lithium-ion batteries (Specification) For Electric Cars:
These batteries are the most widely used in new electric vehicles globally. Nowadays, all EVs with ranges above 150 km use Li-ion battery packs, which often include heat control devices. The current advantage of this technology is its high specific energy. Lithium ion battery specification for electric vehicles is 160 Wh/kg, 450 Wh/l, but this electric car battery cost (700-1000 $/kWh) is still a disadvantage. The main focus is on lowering costs and improving performance while maintaining eco-system greens.
Na – β alumina batteries:
Its performance is comparable to Lion batteries 115 Wh/kg), its power 400 W/kg is superior, and its cost 600 $/kWh is lower than many EV development programs’ targets.
Solid state batteries:
Solid state batteries are the Holy Grail of power storage. In reality, it has been in development for almost a decade. There hasn’t been a substantial breakthrough in commercially feasible performance yet.
Lithium-Ion Versus Solid State Lithium:
Solid state batteries store and release energy in lighter polymers. This method could eliminate the need for rare earth metals and potentially harmful manufacturing processes. Previously, solid state battery concepts could not be scaled up commercially for use in EVs. To overcome this challenge, solid state battery researchers have invested a lot of time and money into developing new batteries that outperform lithium-ion batteries. The most crucial objective is to design a solid state battery that can be mass produced and used in EVs to withstand the future transition to carbon free transportation.
Conclusion: Best Electric Car Battery Compare to Different Types of Batteries Used in Electric Vehicles
Lithium-Ion Batteries Are Popular in Electric Cars. It’s easy to see why lithium-ion batteries are so popular in electric cars. These batteries have a lot of energy for their size.
