Is smartphone battery just charging once a week?

The rapid development of modern technology has brought us increasingly slimmer, more compact smartphones and of course with more supportive features. However, this makes the phone consume more battery power.

If, in the past, a phone only needs to charge once or twice a week (only with messaging and listening functions), now, you often have to charge your smartphone every day if you want to use it. all its functions.

And the inconvenience is that you always have to carry the charger while not everywhere has power for you to use. Researchers were very quick to create a backup battery charger - to help you generate electricity for use wherever you are. However, this power is also limited, and you still fall into discomfort if both your battery and your backup charger run out of power.

Therefore, the demand for permanent batteries is gradually emerging and growing stronger. And scientists are also in the process of finding out what kind of battery can satisfy this user's needs somewhat.

1. Batteries use solar energy and wind power

This is a rather unique initiative. Because the sun and wind are two powerful and seemingly infinite sources of energy. There are now quite a few companies that use this energy to build batteries. More than 20 companies were able to produce batteries strong enough to power grid electricity, and there were even more uses for families using solar panels. However, the wind is not always blowing and the sun is not always shining, so these companies had to create devices to store the energy from the wind and the sun to be able to use it all. at every place

A Tesla Powerwall product is on display in Auckland, New Zealand.

Tesla (TSLA) is an example. The company recently launched two battery products : Powerpack with a capacity of 7 kWh for households, and a 100 kWh powerpack used for industry.

But the experts pointed out that, before being used, the stored energy is also partially wasted. And to be able to get enough power for about 500 recharges, it will need an extremely large battery to store - this could cost millions of dollars.

Therefore, with such a very expensive cost, this is not necessarily a way to create permanent batteries.

2. Permanent Lithium batteries

Imagine that we can live in a world where a laptop never collapses and the phone never turns off suddenly because of a battery outage - it seems impossible.

Last March, South Korea's Pohang researchers said they had developed a " fuel cell" that could power smartphones, spy planes, and laptops. hands, and even electric cars.

"When using this fuel cell, spy planes can fly for more than an hour, and our team expects that phones will only need to be charged once a week," the researchers shared. in a relaxed and relieved way.

But developing this battery does not mean that the next iPhone will have a battery with twice the power. The results obtained in the laboratory will not necessarily be the same when put into practical use.

And because completely switching to a new charging method is time-consuming and costly, so your smartphones still have to wait until these technologies are fully developed and reviewed. , check carefully to put it into practice. Of course, they also need to be reasonably priced to be mass-produced in preparation for a major change in this modern technology.

So let us look forward to the near future, when we only need to charge our phone once a week!

However, this is absolutely no illusion. Now researchers have found ways to store more energy into a tiny battery, helping to bring "permanent batteries" closer to us.

Notably in these "permanent batteries" products are Lithium batteries , developed by researchers at Samsung and MIT. They say the battery can store 20 to 30 percent more stored energy. And especially, they control the heat well, and don't get into the normal hot battery. They say this could be a major change in the battery industry for smartphones in particular and other general battery-powered devices such as laptops, electric cars, etc.
