The super fast-charging electric car battery redefining EV limitations

The automotive industry is on the brink of a revolutionary change in electric vehicle (EV) technology. Long-standing challenges like limited range, lengthy charging times, and rapid battery degradation have deterred many potential buyers from transitioning to electric vehicles. However, a significant breakthrough from a UK startup, Nybolt, promises to address these issues head-on and could redefine how we view and use electric cars.

In a recent live track test, Nybolt's newly developed electric car battery charged from 10 to 80 percent in just over 4.5 minutes. This performance was achieved using a specially designed sports car at a testing ground near Bedford, England. 

The technology marks a potential turning point for electric vehicle adoption, as it drastically reduces the time required to recharge batteries—a critical step toward making EVs more practical for everyday use.

"We started Nybolt in 2019 with a vision to bring down the recharging times to refueling times," Sai Shivareddy, co-founder and CEO of Nybolt told CGTN's Global Business Europe.

"The convenience that we have been used to over many decades driving our vehicles is not there when we switch over to electric vehicles, right? Our vision was to bring down the charging time such that we have the same convenience and a great experience in transitioning to clean energy."

The science behind the breakthrough

Nybolt's technology stems from a fundamental breakthrough in material science about five years ago, involving the discovery of new materials capable of rapid charging. 

"We had new materials that were discovered to charge up the battery fully in a few minutes. For the very first time, we've been able to take all of that new material technology, put it into lithium-ion battery cells using traditional processes, but with our new material inside the cell," says Shivareddy. "This has brought about a full system-level capability to charge the vehicle fully in under ten minutes, depending on the charger."

Addressing battery degradation

Battery degradation has been a major concern for EV owners and manufacturers alike. Fast charging often leads to increased wear and tear on battery components, reducing their lifespan. Nybolt's company has tackled this issue by developing materials that minimize impedance inside the battery cells, thereby reducing heat generation and extending battery life. 

"We have invented these materials to accept a lot of power so they can charge multiple times repeatedly under very fast charge conditions, overcoming the degradation problem," says Shivareddy. 

"By reducing the impedance inside the material, less heat is generated, which means better performance over the battery's lifetime."

Commercialization and future prospects

Nybolt's technology is not just theoretical but has been successfully integrated into existing car platforms. The company is aiming for a phased rollout, starting with small volumes within a year and scaling up to larger volumes over the next three to four years. 

When asked about potential partnerships and the future of Nybolt's battery technology, Shivareddy remains optimistic.

"While we are waiting to roll out our battery into every car on the road that needs a fast charger, we are ultimately looking forward to integrating this technology into a variety of vehicles and devices," he said. "It's an exciting time for us as we navigate the next steps in this journey."
