supercapacitor breakthrough to power more devices - battery energy storage system
Researchers at the University of MalaysiaUiTM)
Taiwan's National Jiaotong University claims that they have found a way to make super capacitors cheaper by using different electrode coating materials.
Dr. Tan Winie, a senior lecturer at UiTM's School of Applied Sciences and Professor of Assoc, said her team had designed a way to replace carbon
Graphene mixtures are industry standards.
Her team uses metal transition oxides, which cost only RM2 per gram compared to carbon
The price of each gram is between RM400 and RM500.
Savings come from the more common materials used-iron, cobalt, and oxide.
The metal transition oxide coating makes the conductor work like a sponge, thus absorbing and retaining more energy, she said.
Super capacitors can be charged quickly, but no batteries are widely used due to low energy density.
So while a typical compact battery in a smartphone can keep it running all day, the equivalent of energy of the super capacitor will be ten times larger.
However, she said that the super capacitors that are built and stacked together in the right way can maintain energy like a battery.
Another advantage of super capacitors is that, unlike batteries, they can be charged over and over without reducing their performance.
Batteries such as lithium batteries-
Ions that rely on chemical reactions to generate energy degrade faster than super capacitors.
For example, Samsung Galaxy Note 9 has a Bluetooth-
Enabled stylus powered by super capacitor.
It takes only 40 seconds to power up the stylus for 30 minutes.
In theory, the S Pen stylus can not only surpass the battery of the phone, but also the phone itself.
A team of about 10 employees from UiTM and 20 employees from the National Jiaotong University took three years to make a breakthrough.
The UiTM team led by Tan studied the manufacturing method of metal transition oxides, while the Taiwan team is developing a new flexible material on which metal transition oxide coatings are applied.
Flexible materials are critical to creating a magnet stack that can store and output more energy.
The UiTM team is still testing the metal transition oxide to ensure it is safe and stable to avoid fire or explosion.
The goal, she says, is to create a charging cycle that will last five years.
However, the test has been slow because it takes a few days to complete just a few thousand recharge cycles.
She believes that industry participants will be interested in new materials and manufacturing methods for super capacitors as they can reduce production costs.
This discovery has won praise from the industry and won a special award and gold medal for the project.
