Promising areas for expanding the functionality of portable electronic devices: foreign experience.
Abstract
The article reveals foreign experience in expanding the functionality of portable electronic devices. Weaknesses of modern portable electronic devices have been identified. It is noted that portable electronic devices, including mobile phones, laptops, tablets and mobile (portable) electronic devices contribute to the rapid growth of information processing and exchange. It is emphasized that the rapid progress of portable electronic devices is impossible without the gradual improvement of battery technology. Primary batteries have been used as the main source of power for portable electronic devices for a long time. Internal and external methods of protection of batteries of portable electronic devices are given. Portable electronic devices with mechanical flexibility (for example, sliding displays) are singled out, they represent a new direction for the electronics industry. In addition, they can be combined with mobile sensors (such as smart clothing) to revolutionize human life. It is emphasized that the electrochemical functions of flexible batteries usually deteriorate during prolonged frequent mechanical deformations, such as bending, folding, twisting and other modes of deformation. With high capacity, fast charging / discharging capability and excellent cycle stability, which can be further combined with flexible electrolytes and separators. It is noted that in order to further meet the ever-increasing demands on batteries in portable electronic devices, significant research efforts around the world have focused on improving existing battery systems using new materials, advanced technologies and new energy chemicals.
