Indian-origin Techie Develops Technology to Charge Phones/Laptops in A Minute and EVs in 10 Minutes

Ankur Gupta, an Indian-origin researcher and assistant professor of chemical and biological engineering at the University of Colorado Boulder, a public research university in Boulder, Colorado, United States, has made a significant breakthrough. His research has led to the development of a technology that can charge laptops and mobile phones in just one minute. Moreover, this technology also has the potential to charge electric vehicles in about 10 minutes.

The key to this innovation lies in the efficient movement of ions within a complex network of minuscule pores, which could lead to more efficient energy storage devices like supercapacitors. Supercapacitors are known for their rapid charging times and longer lifespans compared to traditional batteries. Gupta's work modifies Kirchhoff’s law, which has governed current flow in electrical circuits since 1845, by demonstrating how ions move due to both electric fields and diffusion.

This discovery is not only promising for personal electronic devices but also for power grids, where fluctuating energy demand requires efficient storage to avoid waste during periods of low demand and to ensure rapid supply during high demand¹. It's indeed an exciting development in the field of energy storage and could revolutionize how we charge our devices in the future.

The research is still in the development phase and has been published in the Proceedings of the National Academy of Science. Gupta's team at the University of Colorado Boulder has discovered how ions move within a complex network of minuscule pores, which is a significant step towards developing more efficient energy storage devices like supercapacitors


Ankur Gupta's technology is based on the efficient movement of ions within a complex network of microscopic pores, leading to rapid charging capabilities for devices like laptops, mobile phones, and electric vehicles.

Simplified Explanation of How Ankur Gupta's Tech works:

Supercapacitors: The technology utilizes supercapacitors, which are energy storage devices that store and release energy by accumulating ions in their pores.

Ion MovementUnlike traditional batteries, where ions move relatively slowly, Gupta's technology allows for a more efficient movement of ions. This is achieved by optimizing the flow within a complex structure of interconnected pores.

Charging Speed: By enhancing ion mobility, the charging process becomes much faster, allowing for a laptop or phone to be charged in just a minute and an electric vehicle in about 10 minutes.

Energy Storage: This method is not only beneficial for personal electronics but also for power grids, where efficient energy storage is crucial to handle fluctuating demands.

The breakthrough lies in modifying Kirchhoff’s law, which traditionally describes current flow in electrical circuits. Gupta's research demonstrates how ions move due to both electric fields and diffusion, which is a significant departure from the behavior described by Kirchhoff’s law in a single straight pore.

This discovery enables the simulation and prediction of ion flow in a complex network of thousands of interconnected pores within minutes, which was previously not possible¹. It's a leap forward in energy storage technology, promising faster and more efficient charging for a variety of applications.

The research is ongoing, and it may take some time before we see this technology implemented in everyday devices. However, the potential impact of such a technology on the market and our daily lives could be substantial, offering much faster charging times and longer-lasting energy storage solutions.
