This could be the answer to every smartphone user\'s dream.
A battery that can be charged in just 120 seconds.
According to researchers in Singapore,
Charge the battery quickly and charge up to 70 in just two minutes.
They also live ten times longer than the current battery, and now it is often difficult to keep charging after aging.
Scientists at Nanyang Technological University (NTU) say their breakthroughs are widespread.
Has a wide impact on all industries, especially electric vehicles, consumers have been delayed due to long charging times and limited battery life.
The researchers said.
Drivers of electric cars can save thousands of battery replacement costs and charge the car in just a few minutes.
Electric vehicles can greatly increase their mileage by only five minutes of charging, which is equivalent to the time required for the current car to refuel, said Associate Professor Chen Xiaodong, who led the study.
It is also important that we can now significantly reduce the toxic waste generated by discarded batteries, because our batteries are ten times longer than the current lithium battery life. ion batteries.
Rechargeable lithium commonly used in mobile phones, tablets and electric vehicles-
The charging cycle of an ion battery is usually 500 times.
This is equivalent to a typical use time of two to three years, and it takes about two hours for each cycle to fully charge the battery. In the new NTU-
Developed battery, conventional graphite for anode (negative pole) in lithium)
Ion batteries are replaced by a new gel material made of titanium dioxide.
Titanium dioxide is a rich, cheap and safe material found in the soil.
It is usually used as a food additive or sunscreen to absorb harmful UV rays.
The NTU team naturally found a way to convert titanium dioxide into tiny nanotubes that are thousands of times thinner than the diameter of human hair.
This speeds up the chemical reactions that occur in the new battery, thus enabling ultra-high-speed charging.
Invented by Associate Professor Chen Xiaodong of Nanda School of Materials Science and Engineering, the science behind the formation of new titanium dioxide gel is published in the latest issue of \"Advanced Materials\", the international leading science magazine in material science.

The cycle life of the new battery also means that the driver of the electric vehicle will save the cost of replacing the battery, and the cost of each battery may exceed $5,000.

Ion batteries usually use additives to combine the electrodes with the anode, which affects the speed of electrons and ions entering and leaving the battery.

Electrode-based electrodes eliminate the need for these additives and can pack more energy into the same space.
It is very easy to make this new nano tube gel.
Titanium dioxide is mixed with sodium hydroxide and stirred at a certain temperature, so battery manufacturers will find it easy to integrate new gels into their current production process.

Professor Yazami said that since Sony commercialized ion batteries in 1991, ion batteries have been greatly reduced, performance has also improved, and the market is expanding rapidly, to adapt to new applications in the field of electric mobility and energy storage, he did not participate in Professor Chen\'s research project.
Last year, Professor Yazami was awarded the prestigious Draper Award by the National Institute of Engineering for his research.

Ion batteries with three other scientists.
However, there is still room for improvement, and one of the key areas is the power density-how much power can be stored in a certain space-which is directly related to the fast charging capability.
Ideally, the charging time of an electric vehicle battery should be less than 15 minutes, as demonstrated by Professor Chen\'s nano-structured anode.
