The development of mobile Internet requires the support of mobile power. In this field, there are mainly thin film battery technology, piezoelectric material technology, and wireless charging technology.
In the mobile Internet era, a very important part of the use of the client is its use time. No matter how excellent the performance is, the mobile phone, tablet or other smart products that cannot be kept open when disconnected from the wired power supply cannot be effectively applied.
In terms of ways to increase battery life, a method that can reduce the amount of power used at the same time, such as the iPad, saves all the power consumption methods that can be saved and saves all space that can be saved, but this is for the rapid development of IT products It is really uncomfortable. Another method is to improve the battery's efficiency and provide products with more sustainable battery life. The development of mobile Internet requires the support of mobile power. In this field, there are mainly thin-film battery technology, piezoelectric material technology, and wireless charging technology.
Thin film battery
The most ideal energy source that can be accessed anytime, anywhere is solar energy. The application of solar energy is a problem that human beings have been diligently seeking since the beginning of history. Although monocrystalline silicon solar cells dominate the large-scale application and industrial production at this stage, they also expose many shortcomings, the most important of which is the high cost. At the same time, affected by the price of single crystal silicon materials and the preparation process of single crystal silicon batteries, it is very difficult to significantly reduce the cost of single crystal silicon solar cells.
The alternative thin film solar cells were produced, including amorphous silicon thin film solar cells, indium copper selenium and cadmium telluride thin film cells, and polycrystalline silicon thin film solar cells. The most important advantage of amorphous silicon thin-film solar cells is their low cost and ease of preparation. Since their photoelectric conversion efficiency will attenuate with the duration of light exposure, its instability is also obvious.
As for the indium copper selenium and cadmium telluride polysilicon thin film batteries, the efficiency is higher than that of amorphous silicon thin film batteries, the cost is lower than that of single crystal silicon batteries, and it is easy to mass-produce. There is no sharp reduction in efficiency. It seems to be one of the amorphous silicon thin film batteries. A better alternative. However, the large amount of pollution generated during the production of polycrystalline silicon thin-film batteries cannot be ignored. The raw materials such as selenium, indium, and tellurium are relatively rare metals, and there is little room for further cost reduction.
Polysilicon thin-film batteries use much less silicon than single-crystal silicon, and have no problem of sharp reduction in efficiency. It is possible to prepare them on cheap substrates. The cost is expected to be much lower than that of single-crystal silicon batteries. The laboratory efficiency has reached 18%, much higher than the efficiency of amorphous silicon thin-film batteries. Therefore, polycrystalline silicon thin-film batteries are considered to be the next generation solar cells most likely to replace single-crystalline silicon batteries and amorphous silicon thin-film batteries, and have now become a research hotspot in the international solar field.
The production cost of solar thin-film batteries is low, and its market share has continued to grow in recent years. At present, the highest photoelectric conversion rate is the copper indium gallium selenium solar thin film battery, which can reach 20%, but it is still far away from the theoretical value of more than 30%. The main problem is that the distribution and proportion of indium and gallium in the material are difficult to achieve the ideal value . Wireless charging technology
Despite the high technical requirements of thin-film batteries, in the era of mobile Internet, this is still an industry full of opportunities. Domestically, China is the largest modern home textile manufacturer with the largest export value. Currently, Vosges has two photovoltaic businesses: thin-film solar cell module production, research and development, and crystalline silicon solar cell module production. It is said that its wholly-owned subsidiary Vosges Photovoltaic Technology Co., Ltd. is currently negotiating the next cooperation with Bosch, including plans for share transfer. The copper indium selenium thin-film solar cell module produced by Vosges PV belongs to the second-generation photovoltaic technology with the highest photoelectric conversion efficiency. Its visible light absorption coefficient and photoelectric conversion efficiency are relatively high among all thin-film solar cell materials.
In the United States, the US-rich solar company is also building a large-scale solar thin-film module manufacturing plant in Indiana, perhaps the largest in the nation.
For the application of solar energy, its efficiency and cleanliness are undoubtedly, the effective use of solar thin-film batteries will play a very significant role in the expansion of the use of mobile devices.
Piezoelectric material
Piezoelectric materials are crystalline materials that generate a voltage between the two ends when subjected to pressure. The principle of the piezoelectric effect is that if pressure is applied to the piezoelectric material, it will generate a potential difference, which is called the positive piezoelectric effect; otherwise, when a voltage is applied, mechanical stress is generated, which is called the reverse piezoelectric effect. In recent decades, the use of piezoelectric materials has been gradually expanded, and it is now found to be the most practical new energy for human beings. The use of piezoelectric materials for the wind turbine blades of wind generators and electric fans, combined with the new air energy, does not affect the function and efficiency of wind generators and electric fans, and can achieve without having to consume any additional energy. Practical value of electrical energy can improve the efficiency of wind turbines, enable electric fans to become generators, and increase the efficiency of new air energy by multiples.
Piezoelectric materials are currently the most ideal new energy materials. The combination of piezoelectric materials and air new energy sources can produce energy that can meet the energy needs of all human beings. If the energy of this new structure is fully used, It can further reduce greenhouse gas emissions, slow down the rate of global warming, and guide the development of the human environment to benign.
The most important thing in wireless charging technology is two things, one is the sender on the socket, and the other is the receiver on the electronic product. As long as it is within a certain range, the power can be effectively transmitted instantly.
On September 1, 2010, the world's first wireless charging technology standardization organization, the Wireless Charging Alliance, announced in Beijing that it will first introduce Qi wireless charging international standards into China. The Communication EMC Quality Supervision and Inspection Center of the Ministry of Information Industry also joined the organization. LG Electronics also launched its first wireless charger WCP-700.
The wireless charging technology adopts a unified industrial standard. For mobile phones, PMP / MP3, digital cameras, laptop computers and other products, the same new wireless charger with low energy consumption and high compatibility can be used. This charger is similar to a tray that is directly plugged into the power supply. The mobile phones of different brands with the "Qi" logo of various enterprises that have been certified by the alliance are directly placed on it to complete the charging. For different electronic products, the power supply interface can automatically correspond. When charging is required, the transmitter and the receiving chip will automatically start working at the same time. When fully charged, both sides will automatically shut down. It also automatically recognizes different equipment and energy needs and performs 'personalized work', which is intelligence.
On March 30th, ST-Ericsson, a mobile platform and semiconductor company, launched a power management solution that greatly shortened the time it takes to charge a wall outlet relative to a mobile device. This innovation is one of its PowerHUBTM products, which can collect energy from many channels, which not only allows users to charge faster, but also effectively reduces greenhouse gas emissions.
Now, for the safety and convenience of consumers, wireless charging technicians have started further research on long-distance charging while developing short-range wireless charging technology. Once this technology is implemented, not only low-power mobile devices, even household appliances, medical equipment, office appliances, etc. can be wirelessly charged, and can be used while charging without batteries.
