One of the considerations for many car buyers interested in a electric vehicle is the battery life. A team of Russian researchers recently achieved a breakthrough in improving electric vehicle batteries, detailed in their study. paper published in ScienceDirect.

High energy density lithium-ion batteries (LIBs) are increasingly in demand. These batteries are used in a variety of devices – from the cell phone in your hand to the laptop on your desk to the electric vehicle in your driveway.

The new method discovered by the research team could improve the capabilities of LIBs that power many devices we use in our daily lives, including EV.

Nickel-rich complex layered oxides are commonly used to fabricate cathodes in LIBs. Cathodes allow current to flow from a battery and play a key role in determining the cost, cycling, capacity and thermal capabilities of a LIB.

The researchers used ultra-high nickel layered oxides to increase energy density; however, a higher nickel concentration can lead to microcracks.

To solve this problem, the team controlled the microstructure of the material and used plate-shaped particles to enable uniform expansion and contraction.

Additionally, the team used a cobalt-rich coating on the surface of the cathode material to also prevent microcracks and improve mechanical stability.

Overall, the authors of paper noted a greatly improved cycling stability (the lifespan of the battery) and a high specific discharge capacity (improved autonomy).

VE popularity has increased over the years. According to OUCHnearly one in five cars sold worldwide in 2023 was an electric vehicle. As the demand for electric vehicles has increased, so has the demand for better battery performance.

If you were to buy an electric vehicle, which of these factors would be most important to you?

Findings like the one presented in this article could encourage further growth in the sector. Electric vehicle industryallowing more drivers to enjoy the benefits of ditching their gasoline-powered vehicles.

Electric vehicles increase the energy security by reducing our dependence on dirty fuel. They also save drivers a lot of money since they don’t require expensive gas and don’t need as much maintenance.

They’re also better for the environment, as they reduce toxic pollution that causes global temperatures to rise. The climate crisis has caused extreme weather conditions events are getting worse, putting human lives at risk, and air pollution has been associated with a premature phenomenon. death and illness.

Switching to an electric vehicle is great for your wallet and your health. Advances in electric vehicles technology – including batteries – help make electric vehicles a smart choice for more consumers, helping to reduce pollution and create a safer environment for us all.
