Scientists at Nanyang Technological University (NTU) in Singapore have developed supercells
Charge the battery quickly and charge up to 70 in just two minutes.
The life of the new generation battery is also more than 20 years, which is more than 10 times that of the existing lithium battery. ion batteries.
This breakthrough has a wide range
Has a wide impact on all industries, especially electric vehicles, consumers have been delayed due to long charging times and limited battery life.
With this new technology from Nanda, electric car drivers can save thousands of battery replacement costs and charge the car in just a few minutes.
Commonly used in mobile phones, tablets, electric vehicles, rechargeable lithium-
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, the international leading science magazine in material science.
Professor Chen and his team will apply for a certificate. of-
Building a large concept authorization
Scale battery prototype.
With the help of NTUitive, a complete
Nanda subsidiary established to support the launch of Nanda-
Patent technology has attracted interest in the industry.
The technology is currently getting a final production license for a company.
Professor Chen expects a new generation of fast-
Charging batteries will enter the market in the next two years.
It also has the potential to be a key solution to overcome the long-term power problems associated with electricitymobility.
\"Electric vehicles can significantly increase their mileage by only five minutes of charging, which is equivalent to the time it takes to refuel the current car,\" Professor Chen added . \".
\"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 generation time. ion batteries. ”The 10,000-
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.
According to Frost & Sullivan, the main growth

The ion battery is expected to be worth $23.

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.
However, Professor Chen\'s New Cross
Titanium dioxide linked-
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 Richard Yazami
Inventor of lithium
Graphite anode used for lithium today 30 years ago-
Professor Chen said that the invention of ion batteries is the next major leap in battery technology.
\"And the cost of lithium --
Since Sony commercialized the ion battery in 1991, the ion battery has been greatly reduced and its performance has improved. The market is rapidly expanding to adapt to new applications in the field of electric mobile 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.
Breakthrough work to develop lithium
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 amount of space-which is directly related to the ability to charge quickly.
Ideally, the charging time of an electric vehicle battery should be less than 15 minutes, as demonstrated by Professor Chen\'s nano-structured anode.
\"Professor Yazami is now developing new batteries for electric vehicle applications at the Nanda Energy Institute.
The battery research project took four scientists three years to complete.
It is funded by the National Research Foundation (NRF) of the Prime Minister\'s Office of Singapore, under the campus of its energy and water management nano-materials research excellence and technology enterprise project.
