The battery in the iPhone is a gift to many, and at the same time a curse

A gift – because lithium-ion and lithium-polymer batteries better than any other types. With a record up to the present time, the charge density, and many other characteristics, they are the best. But, in addition, they ignite for a variety of reasons – damage, abuse, overheating and that’s not all possible reasons, and they are very difficult, almost impossible, to extinguish. When burning these batteries release oxygen, and therefore prevent the access of air to them is useless. Any water or other fluid used when extinguishing a fire, is also not working. You can only prevent if possible the spread of fire to other items and “to bring down his temperature.”

The battery is the most important part of the iPhone (after chip)

During their practical application (they are on the market since 1991), they have become a real serial killer. In the list of their victims – Apple PowerBook 5300, the Samsung Galaxy Note 7 and even a mobile device as the Boeing 787. From 2009 to 2017, according to data of American firefighters in the United States, they have 195 fires and explosions. And casualties on account of the many – but all attempts to replace them with something less bloodthirsty, alas, failed. Tried lithium is to use another alkaline metal, sodium, but against nature will not go: the charge density of these batteries is lower than lithium-ion and lithium-polymer by ten percent, making them unacceptable to the manufacturers of any devices where every extra gram of weight or cubic millimeter of space at a premium. This is the first. Second, though they are less dangerous than lithium-ion batteries, but still dangerous.

The main thing that will remain after the Apple is its contribution to the development of health

Apple really makes very much of this. The fact that all this is done from the usual “selfish” motives does not invalidate the results of those actions. But just groove when I hear about Apple health and I remember the incident in China a few years ago. A young Chinese man passionately wanted to purchase the latest iPhone at the time of the model – that he had neither money nor hope to earn them. And then he sold one of his kidneys. Failed. Problems in this operation, albeit infrequently, but it happens. He died. I don’t believe Apple are guilty of this, but osadochek left.

Apple cares about the environment: the headquarters of the company, and almost all offices of the company in the United States and beyond, use only renewable energy. Mac and iPhones, iPads and its other products do not contain harmful to health or to the environment components. Touching. They often talk about it that is annoying. But all of these statements is necessarily confirmed by certificates from independent institutions, and almost certainly all of this is true. Apple are doing everything in their power to save peace and nature. Not only in the Apple: poisoned to death in the once great rivers of Europe has again caught fish of sturgeon species can live only in clean waters. But lithium-ion and lithium-polymer batteries in Apple products, of course, if they do not disassemble in the home, almost safe – but with the materials from which they are produced is not all right. More precisely, their prey.

A large part of the lithium is extracted in South America, the Chilean company SQM (Sociedad Química y Minera), 51% owned by a Chinese company Tianqi (read “Tanzi”). And the process of extraction, has not changed over the past 15 years, cheap and angry. The need for lithium could go on the decline, the production of mobile and portable devices in the world declining for several years, but on stage there is another eater lithium, these are the electric cars, which is considered to be an ecological form of transport. Where they are used, indeed, the air is cleaner. But lithium-ion batteries of these eco-friendly vehicles are forced to produce more and more lithium. Causing more irreparable damage to the environment of poor countries.

In lithium-ion batteries lithium is used for the manufacture of anodes. The cathodes in them, often made from cobalt. A very harmful metal, almost 90% of which is mined in the Congo. From 2012 to 2019 ton of this metal has risen from $ 20 000 to 80 000. The development of IT-technologies and environmentally friendly transport really changes the world. And not always for the better. The growth in demand for cobalt leads to an increase of its production, and it is, as it usually happens in underdeveloped countries, on the environmental side of the issue are not paying attention. Voluntarily no one would bother with such nonsense, in the US, Apple and other giants of the IT industry suddenly preoccupied with these issues at one and the same time. When the use of harmful materials in their products they were forced to pay. Helped.

What does Apple?

Apple from time to time, investing billions of dollars in all, at first glance, nonsense. Apple – the woman and very rich. In fact, even very intelligent. Investing billions of dollars in the construction of power plants in China using renewable energy sources, Apple earns a special reputation in the eyes of the Chinese leadership. And it is the second largest market for the company. Apple invested in other areas of life in mainland China, and in response, the inevitable in any collaboration critical situations, companies almost always go forward. The same thing, though much later, the company started to make at home. The results of this will write soon.

Apple is one of the best teams in the world on the development of batteries. Here for twenty years it works wonders, features battery Apple over and over again to be simply impossible technically, but they are real, they are every time meticulously studying experts from regulatory bodies, and every time it ends with the recognition of their safe and their parameters meet the stated Apple. How did they achieve this – of course – secret. Few working in Apple knows where this group, especially its laboratories and test stands. Probably not in a glass house. But that’s just my assumption.

In Switzerland, for several years there has been the development of lithium-ion battery with solid state electrolyte that is significantly more secure than conventional, used in the vast majority of mobile devices (even Boeing). And it seems that the emergence of such a battery on the market, with high probability, is not far off. Apple could take part in it, it would improve her karma, it would be another reason for PR, that would be great. Looks like Apple are thinking the same thing. The contact between Apple and the developers recorded by European observers. Maybe something actually happens?

And, but this is purely my personal opinion, if Apple has taken care of those who mines lithium and cobalt, such as environment, health, and other things, harm to no avail.

About the batteries in Apple and Pencil Apple Pencil 2

Charging port for Apple Pencil

This question has long interested me, and I finally got the opportunity to ask those who know. How unused pencils can be stored in a trading network for months (and even years), but is still workable – and after the first activation, to demand regular and frequent recharging? Quite simply, the technology of this trick is not invented at Apple, and has long been used by other companies. In the electrolyte of the battery is added a small amount of a special chemical composition, called “inhibitor”, ostanavlivayas almost all processes in it. But, when you first use your battery, the inhibitor is destroyed, and the rules of the game change. Sorry for this offtopic, but it seemed appropriate.
