LITHIUM ION BATTERY GENERAL ISSUES III: 


Q100: What are smart secondary batteries?

Equipped with a chip in the intelligent battery, not only to provide power supply for equipment, and can control its main functions, this type of battery can also display the number of residual capacity, has been circulating, temperature, etc., but not smart batteries sold on the market at present, the future will occupy the main market position - especially in camcorders, cordless phones, mobile phones and laptops.


Q101: What is a paper battery?

Paper battery is a new kind of battery, its component also includes electrode, electrolyte and isolation film. Specifically, the new paper battery is composed of cellulose paper with embedded electrodes and electrolyte, in which cellulose paper ACTS as a separator. The electrodes are carbon nanotubes added to cellulose and lithium metals coated on cellulose films. And the electrolyte is lithium hexafluorophosphate. The battery folds flat and is as thick as paper. The paper battery will become a new kind of energy storage device because of its many properties, the researchers say.


Q102:What is a photovoltaic cell?


A photovoltaic cell is a semiconductor device that generates electromotive force in the presence of light. There are many kinds of photovoltaic cells, such as selenium-photocell, silicon-photocell, thallium sulfide, silver-sulfide photocell and so on. Mainly used for instrument, automatic telemetry and remote control. Some photovoltaic cells can convert the sun's energy directly into electricity.


Q103:What are solar cells? What are the advantages of solar cells?


Solar cells are devices that convert light energy, mainly sunlight, into electricity. The principle is the photovoltaic effect, that is, based on the internal electric field of PN junction, the optical voltage is generated when the optical carrier is separated to reach both sides of the junction, and the power output is obtained when connected to the external circuit. The power of solar cells is related to the intensity of light. The stronger the light, the stronger the power output.


The solar system is easy to install, expand and disassemble. At the same time, the use of solar energy is also very affordable, in the operation process heavy energy consumption. In addition, the system is resistant to mechanical wear. A solar system requires reliable solar cells in order to receive and store solar energy. General solar cells have the following advantages:


01) high charge absorption capacity;

02) long cycle service life;

03) good filling performance;

04) no maintenance.
