Although the iPhone 8 and iPhone 8 Plus are better than the previous Apple series phones in terms of material sele...

Recently, according to foreign media reports, two technology companies in the United States, Sila Technologies and Angstron Materials, have developed a new lithium-silicon battery technology and announced that in the next few years, this new type of battery technology can be produced on the ground, allowing mobile phones and automobiles to be produced. , smart watch batteries increase 30% or more power. The core of this new technology is "anode fabrication." Current battery anodes are made of graphite, while new battery anodes are made of silicon and can store more power. However, under the conditions of actual use, silicon anodes are often fragile or have a short life span and are difficult to popularize. The prototype products developed by Sila Technologies have successfully solved these problems. It fuses silicon with graphite nanoparticles to make the product more durable.

The sponsors of the 2020 Tokyo Summer Olympics plan to produce gold, silver and bronze medals using metals recovered from discarded smartphones, and other electronic products. The report said that the organizers of the Tokyo Summer Olympics, Japanese government officials, and related corporate executives discussed the proposal for the first time at a meeting hosted by a Japanese non-governmental organization in June, hoping that this move would increase people’s so-called "E-waste" awareness, but Japan will need to implement a more comprehensive system to collect waste electronic products. Compared with other countries, Japan is not a resource-rich country, but the country does have a huge “urban mine” that can find precious metals in electronic waste. The proportion of gold and silver contained in waste electronic products in Japan accounts for 16% and 22% of the global supply respectively. The metal from e-waste should be sufficient for making Olympic medals. The me...

1. Adolescents and pregnant women must be careful to use old mobile phones because the longer the age of mobile phones, the aging of the batteries, the stronger radiation they emit, and the greater harm to the human body. Children and adolescents who are at the stage of brain development, their brain tissue is more capable of absorbing electromagnetic waves than adults. The first trimester of pregnancy, known as early pregnancy, is an important stage in the differentiation and development of embryonic tissues. To avoid fetal anomalies, small electronic products should be used. 2. Discard old mobile phones should also stay away from children! Mobile phone replacement is fast, many parents like to play with children, but do not know the old mobile phones do not have a lot of bacteria we can not see on the naked eye, the baby is sometimes placed in imports, plasticizers, etc. can affect the endocrine, development through the skin Wait. More seriously, parts of the mobile phone containin...
