When it comes to electronic devices, particularly smartphones and tablets, battery life is one of the biggest issues consumers rant about.
If you’re one of these people – and if you use a smartphone regularly then you probably are – good news! Your battery life woes will soon be a thing of the past. Researchers from Singapore’s Nanyang Technology University (NTU) have developed a groundbreaking new lithium-ion battery technology that can charge your phone to up to 70% in as fast as two minutes.
Currently, our lithium ion batteries have a lifespan of over 2 years and can charge at approximately 500 times. In contrast, these new lithium-ion batteries have a lifespan of over 20 years and can be charged up to 10,000 times. This new technology is a giant leap in the world of electronics!
How does it work?
The new battery technology replaced the negative pole (which was traditionally made from graphite) with titanium dioxide – an abundant mineral found in soil, which is used in everyday products such as sunscreen and food additives. The engineers from NTU used this new mineral in a gel form and transformed it into very miniscule nanotubes, which made way for a faster reaction process, enabling the batteries to be recharged at an exponentially faster rate.
A groundbreaking innovation
With this technology, electric vehicles can be charged 20 times faster, with the added benefit of not having to change them as often. This new technology’s environmental impact is also exponentially lower than that of the old technology – not to mention more economical as the battery lasts longer, which means less electronic waste and less money spent on battery replacements.
According to creator Professor Chen Xiaodong from NTU’s School of Materials Science & Engineering, the technology is expected to be released in the next two years. It’s currently undergoing licensing and he and his research team are also applying to get a grant to be able to produce a prototype of a larger scale.
