Samsung's phone debacle demonstrates why we need a battery revolution - lithium ion battery manufacturers

What if I told you that you often carry a miniature explosive device that could be lit in the wrong case and could cause significant damage?
You may be directed to deal with it urgently or at least start keeping it in length.
Actual cost of related equipment
The time in our hands is not long, or pressed directly on our faces.
It's lithium-
An ion battery in the middle of a smartphone.
Samsung is strongly reminded of the explosion of lithium
Last week, when a series of nightmares involving the overheating, fire and explosion of its latest phone forced it to recall millions of phones, stop production and write down billions of dollars in profit losses.
If the company knows about itself, it still doesn't say exactly what's wrong with the Galaxy Note 7.
At first, it blamed the rogue battery made by SDI, one of its subsidiaries, and I think solving the problem was just changing a new one when replacing the first batch of problematic phones.
But the phone continued to explode.
In the various explanations that are floating now, there are fragile materials that fail to separate the active elements of the battery, and the waterproof seal of the Note 7 prevents heat from escaping from the phone, simply put, the processor of the phone was pushed too tightly.
Samsung is frantically investigating to find out the answer, but what we can be sure of is that the basic nature of the battery itself is aggravating any malfunction. The lithium-
Ion batteries that power mobile phones, laptops and billions of other consumer products are a veritable fire box.
When it generates a current that supplies electrical equipment, it is carefully controlling the strong reaction between several volatile elements in dense space.
If a row in the equation goes wrong, the result may be similar to an unsupervised high school chemistry experiment. Lithium-
Since Sony commercialized the concept in 1991, ion batteries have not changed much, but consumer electronics have changed.
Smartphone makers are racing to pack more features into razors
While keeping prices down, thin phones on a large scale.
In the end, a 25-year-
The old technology will be beyond its limits.
While Samsung should obviously be more strict with quality testing, this is by no means the only one.
The entire fleet of Boeing 787 Dreamliner was suspended in 2013 due to an electrical failure on the aircraft due to a battery failure.
Ten years ago, Dell was forced to recall millions of laptops because of a battery explosion.
At the end of the market budget, the risk is even greater: Officials of Trading Standards imported thousands of "hovercraft" scooters from China last year.
And the fault is often divided
The standard plug or cable, the battery is on fire. That lithium-
Ion is still the dominant technology, which makes people more curious because consumers are frustrated with the poor battery life they get from their phones.
While processors, screens and cameras have improved exponentially over the past few years, the battery has no Moore's law;
Instead, engineers try to improve efficiency by a percentage point.
Even in the case of moderate use, most smartphones will last for a day or less, and we are now so dependent on them that a dying phone can trigger constant anxiety
It only gets worse when our car is battery
Therefore, solving the battery problem is one of the big prizes in the technology field.
Imagine the success of a phone that lasts for a week: everything else becomes redundant immediately.
Of course, electronics companies are not blind about it. Lithium-
Ions have not yet been replaced, partly because of the (relative) efficiency of the technology and partly because it is very difficult to improve it.
But given the loot of those who did find the magic recipe, it's not surprising that some of the best engineers in the world are working on it, and the recent breakthrough gives an optimistic reason.
Cambridge scientists announced a breakthrough last year.

Electric micro-fuel cells can power the iPhone for a week (although recent cash problems and the brutal restructuring of the company didn't inspire confidence ).
While these technologies may not be more secure in nature than they are today, their additional capacity may prevent manufacturers from pushing them beyond their safety limits.
Other designs, such as entities
The state battery replaces the water and flammable electrolyte passed by particles in modern batteries, thus improving reliability and performance.
Dyson, known for his bag-free vacuum cleaner, is investing billions of dollars to push the solid-
Status battery forward.
It describes increasing energy density as "the biggest challenge of the 21 st century," suggesting that its ambition for the technology may not be limited to household appliances.
None of this can replace lithium.
They need years of testing and safety certification.
Samsung's failure will be a warning for any manufacturer considering overtaking itself.
But it should also remind us why a new type of battery should have been used long ago.
