Mobile phone battery technology encountered difficulties, the future development of the road is how?
With the development of science and technology, the performance of the smart hand is getting higher and higher, the screen is getting bigger and bigger, the resolution is getting higher and higher, the camera is more and more advanced ... but the smart phone in the screen, motherboard and computing speed and other rapid iteration at the same time, More and more exposed a short board, that is, battery technology, although the mobile phone battery has experienced three stages of growth, but this is difficult to overcome the development of smart phones a difficult problem. Italian dragon has been thinking, in the fast charge technology development at the same time, the future development of battery technology is how the road?
Nickel-cadmium batteries are the first to use the battery on the phone. This nickel-cadmium battery has two main features: the first is that this battery is very large, accounting for almost half of the size of the phone and weight, making the early mobile phone volume is very large. The second is the nickel-cadmium battery "memory effect." Many people should remember that the original cell phone battery is the first discharge to empty the power to be able to charge, or the battery capacity will become much smaller, and even full of electricity can not take a few hours.
The second stage on the stage of history is nickel-metal hydride batteries. In 1998, nickel-metal hydride batteries began to be used in mobile phones, nickel-metal hydride batteries than nickel-cadmium batteries lighter, thinner, non-toxic and more energy density, has made great progress, while the battery memory effect is greatly reduced. However, the heat problem still exists, will still be deformed.
The emergence of lithium batteries for mobile phones is epoch-making significance. Lithium battery is a "lithium" bit cathode material of the battery, mainly divided into lithium metal batteries and lithium-ion battery. At present, we commonly used mobile phone batteries are generally lithium-ion battery. Lithium-ion battery is very light, and the energy density than nickel-metal hydride batteries increased by three percent, and no memory effect.
Lithium battery is currently our large-scale popular mobile phone battery, but after the emergence of smart phones, mobile phone power consumption is growing, the traditional battery has been unable to meet the daily needs of the. Although the battery technology is also rising, but compared to mobile phone processors, memory, screen technology and other aspects of the rapid development of the battery development is very slow, the future constraints of mobile phone technology development is likely to be battery technology.
So how will the future mobile phone battery in the end? According to the survey found that the major manufacturers have two aspects to solve the battery dilemma. The first aspect is in the original lithium battery on the basis of improvement. At present, mobile phones are generally non-removable battery, so that the battery can save the extra packaging, the same volume can have a greater battery capacity. At the same time, the major battery manufacturers are also studying new technologies to make lithium batteries to promote.
On the other hand is to find new materials applied to the battery up to expand the battery capacity. Scientists continue to discover new battery materials, allowing the battery itself to greatly enhance the endurance, which in turn the most representative of graphene. Graphene conductivity than metal copper is good, and light weight, large surface area, is the development of large-capacity battery ideal material, while both the strength and flexibility. But the price of graphene expensive, so Ken Xinda from the current point of view, the most practical is based on the original lithium-ion battery to be improved to improve the battery capacity.
