Evolving Battery Technologies for Electric Vehicles

Auto Tech Outlook | Tuesday, December 08, 2020

Engineers from a university created a battery with components of urine– urea as electrolytes. This non-flammable battery is coupled with aluminum and graphite electrodes, making it more competent and inexpensive. The test results demonstrated a moderately swift charging speed delivering over 1500 charges per rotation.

FREMONT, CA: As the new car models are becoming more evident, Electric Vehicles (EVs) are subsequently gaining real traction in the market. Much research and development are being done on battery technology to enhance performance while ensuring that batteries are compact, lightweight, and affordable. The emerging battery technology for EVs includes:

UREA Batteries

Waste products from the brewing industries became critical ingredients for energy generators and storage systems. Engineers from a university created a battery with components of urine– urea as electrolytes. This non-flammable battery is coupled with aluminum and graphite electrodes, making it more competent and inexpensive. The test results demonstrated a moderately swift charging speed delivering over 1500 charges per rotation. With all the convivial features in an EV Battery, the charging rate is fast, and the smaller capacity may not be a matter with lower expenses. It is suitable only for stationary appliances.

Aluminum-Air Battery

This battery technology uses oxygen naturally in the air to fill its cathode, making it far lighter as equated to the liquid-filled lithium-ion giving the car a more excellent range. Aluminum-air batteries exhaust by turning into aluminum hydroxide that can later be utilized to make fresh batteries leading to replacing batteries every few months. The automakers need to implement efficient and cost-effective batteries offering huge mileage and affordability. It may be one of the technologies which one will see in the bonnets.

UltraBattery

One institute is presently evaluating a hybrid lead-acid battery known as the ultra-battery with an integrated supercapacitor. The technology has multiple energy storage systems with a program of rural electrification. Currently, in rural locations, diesel is being used to generate power that pollutes the air and is costly. It is anticipated to replace the mini-grids made of solar displays and energy storage structures.

Sodium-Ion Batteries

The sixth most natural element on the planet, sodium, is substituted in place of lithium by Japanese scientists that is seven times more competent than the standard batteries. With the rise in battery-powered cars, lithium will become rare and expensive; ultimately, replacing it with the most common element will make the batteries inexpensive.
