Five Emerging Battery Technologies for Electric Vehicles
Published : 01 Jun 2021 Industry: Automotive
Battery technologies have become critical for success in a carbon-constrained world that uses intermittent sources like solar and wind or that worries about resilence in the face of natural disasters. New and improved discoveries in the battery technologies are taking place which includes features from over the air charging to superfast 30- second recharging. With a large number of researches conducted in the past few years, the researchers have come up with the following emerging battery technologies for electric vehicles:
Vertically aligned carbon nanotube electrode battery:
Recently NAWA technologies has designed a vertically aligned carbon nanotube electrode battery which can boost the battery power ten fold, increase energy storage by a factor of three and increase the lifestyle of a battery five times. It also brings significant environmental advantages such as ultra fast carbon electrode is easily recyclable, eco-disposable at the end of its lifecycle offering potential Co2 footprint reductions as high as 60 percent in applications.
Another emerging battery technology for electric vehicles includes structural batteries developed by the engineers at Charmers University of Technology which has the potential to reduce structural components in 2021. It can perform 10 times better than all the previous versions. In the electric cars, these batteries can work both as a power source as well as part of the structure such as body of the vehicle.
Cobalt-free lithium-ion battery:
Researchers from the Cockrell School of Engineering at the University of Texas have recently introduced a cobalt- free lithium- ion battery by eliminating cobalt from it. Eliminating cobalt ensures good battery life and even distribution of ions.
Solid State Li-ion Batteries
- Tufts University Professor Mike Zimmerman confronted the explosive problem of the lithium-ion by eliminating the liquids. He examined both the benefits and drawbacks and finalized a solid polymer electrolyte which would be safer than the currently used liquid.
This solid Li-ion battery can be sliced and deflated without an explosion or a breakdown. The polymer electrolyte is fire resistant and does not allow dendrites to appear on the electrode, increasing the battery life and number of charging rounds.
Although the battery is fully functional and works great on small devices like smartphones, improving the battery’s energy compactness, charging rounds and manufacturing with reduced cost will certainly add up to the current disadvantage.
- Waste products from the brewing industries became the main ingredients for energy generator and storage system for the companies like Cambrian Innovation and Kona Brewing Company.
Engineers from Stanford University created a battery with components of urine – urea - as electrolytes. This non-flammable battery is combined with electrodes made from aluminum and graphite making it more efficient and inexpensive.
The test results illustrated a moderately swift charging pace delivering over 1500 charges per rotation. With all the welcoming features in an EV Battery, whilst the charging rate is fast, and the smaller capacity may not be a matter with lower costs, for now, it’s suitable only for stationary appliances.
Within the last decade or so, electric vehicle technology has gained momentum. Tesla, the first to start the EVs was later joined by the companies like Nissan, Porche, Chevy and BMW. Now, a latest announcement has come that Volvo will start manufacturing only electric vehicles after 2020. This announcement can have wide-ranging ramifications on the global electric car battery market.
These vehicles would not have been seen on the road without the lithium-ion battery, which is right now the most preferred battery type, which can last up to 200 miles i.e. 321.86 kilometers on a single charge. This makes EVs affordable and also less expensive.
But as is the case with every other new technology, lithium-ion batteries too have disadvantages and are in desperate need of a makeover, they still can’t beat the combustion engine cars in terms of speed and power. Safety, on the other hand, is again a major concern as lithium-ion is not the best storage device.
The tech columnist for Yahoo Finance, David Pogue says that this decade old technology is explosive and expensive too and has limited battery life. The emerging battery technology for electric vehicles includes,
These are the emerging battery technologies for electric vehicles. As electric vehicles transform from being a buzzword to the future of automotive, investments in R&D will witness an increase.
