phone battery – The new ultra-high capacity lithium-sulfur battery can make a breakthrough in the world of electric-powered cars at much cheaper prices than are currently available on the market,
In addition to increasing the capacity of energy storage in electrical networks,
According to the American “New scent” website.
5x higher capabilities phone battery
- Mahdukt Sheibani, in collaboration with her colleagues at Monash University in Melbourne, Australia,
From developing a battery that is 5 times more powerful than lithium-ion batteries.
- And the innovative battery features the ability to continue to work with efficiency up to 99% for more than 200 cycles, and the version will be from the new batteries,
Which is proportional to the size of the smartphone, able to keep the phone charged for 5 days.
Solve expansion and contraction problems
The problem with lithium-sulfur batteries was and still is that the sulfur electrode capacity is so great that it is separated from the charge and discharge cycles,
- Thus, the power feature quickly disappears when the electrode breaks down, and the battery charge immediately disappears. “
- Sheibani explains that this problem occurs because of the expansion and contraction of the sulfur pole during its rotation,
where the percentage change in volume reaches about 78%,
In addition to a change in the size of the electrodes in lithium-ion batteries,
used in the operation of electric cars and smartphones,
it happens about eight times less.
- To avoid the electrode disintegration problem in the lithium-sulfur battery,
- The researchers gave the sulfur particles more room to expand and contract,
- Typically, lithium-sulfur batteries contain additives that bond molecules together inside so that the battery does not crack during expansion and contraction.
Sheibani and her team used less polymer bonding material in their innovative electrode to build structures with more sulfur particles apart.
This little polymer helps build a series of bridges between particles,
- As an alternative to the traditional dense grid, it helps to balance the battery’s resistance to cracking and its ability to discharge a large amount of energy.
The team of researchers is studying prototypes of the new battery now,
As a prelude to starting commercialization in Australia in the coming years.
