Lithium battery technology company "curse"

Huawei glory 6, a 2014 mobile phone, had little previously reported battery problems. In fact, cell phone battery problems are nothing new, but this year for a big tech company, battery problem fans are a bit harsh mouth.

If all the punters were asked to name one of the most "explosive" mobile news of the year(none), I'm afraid Samsung's phones would be the last. The much-anticipated Galaxy Note 7 has been so unimpressive that it has repeatedly exposed the problem of battery explosions around the world. Samsung has been left with a huge lead, and when will it be able to recover? God knows.

Samsung Apple has planted lithium batteries as a "curse" for technology companies

And let "fruit powder" and eating melon people did not expect that Apple actually fell on the cell phone battery. Earlier this month, Apple also had to post "information about iPhone and accidental shutdown" on its website because of battery problems, explaining why iPhone 6s users reported automatic shutdown when the iPhone had half or even 80 % power. He said he would replace the batteries of the affected devices for free -- this time including Chinese users.

Samsung Apple has planted lithium batteries as a "curse" for technology companies

Battery problems, like the curse of technology companies, can be a little embarrassing. But why the battery?

The volumetric energy density of batteries is the focus of attention of manufacturers. Everyone is frantically seeking to load more and more power into a limited volume, so that their own mobile phones can have longer endurance. However, the battery does not agree. Under the current technical conditions, especially due to the limitations of battery materials, the increase in battery energy density is a gradual process. On the basis of existing battery materials, it is quite good to have an annual increase in energy density of 2 % to 3 %-This has long been the consensus of the industry. What is fatal is that the development of the electronics industry, relative to the energy storage industry, reflects the well-known Moore's Law. The number of integrated circuit chips that can accommodate transistors has increased exponentially, and it can double approximately every 18 months. This leaves a terrible scissor gap between the improved performance of electronics and the increased energy density of batteries.

However, mobile phone manufacturers do not give up. As the energy density of the cell phone's battery is approaching its limit, it is still trying to squeeze the auxiliary material space and "slim down" the battery to squeeze out the last chance of increasing the power. However, "slim down" and "safe" on the mobile phone lithium battery is difficult to get both. So ...

Wake up, no matter what kind of product you are, safety comes first.
