Consumer electronic battery technology needs to change
Recently, well-known experts in the industry, Professor Xia Yongyao of the Department of Chemistry of Fudan University, and Director Zhou Bo of the Research Department of the Power Battery Application Branch of the China Chemical and Physical Power Supply Industry Association, accepted an interview on this website and shared the comprehensive arrival of the 5G communication era on the technology belt of consumer electronic batteries. Challenges and subversions coming.
The Internet of Everything is inseparable from strong "power"
Tablet computers, Bluetooth speakers, smart phones, consumer robots, as the types of consumer electronic products continue to increase, on the one hand, the emergence of these consumer products brings people a truly convenient experience; but on the other hand, people also We often see actual users of such products complaining that the products are unsatisfactory in one way or another.
"The arrival of the 5G era is not just about changing network speeds, but also a series of power support systems." Zhou Bo, director of the Research Department of the Power Battery Application Branch of the China Chemical and Physical Power Industry Association, believes that if the Internet allows The connection between people and things is more closely integrated, so the arrival of the 5G era will not only increase the speed of this connection, but also enable basic coordination between things.
"The mobile phone is out of power and there is an emergency. At this time, we especially hope to have a mobile phone battery with a lot of power." Zhou Bo said that most of the batteries used in mobile electronic products such as mobile phones and tablet computers on the market are mostly lithium. Ion batteries, although designers have been using various methods to increase the capacity of the battery, it is still more painful compared to the rapid innovation speed of consumer electronics.
Zhou Bo believes that the 5G era of the Internet of Everything will undoubtedly drive the demand for hardware performance of various mobile devices, including mobile phones, wearable electronic products, Internet of Things devices, drones and so on. In this context, whether the battery's endurance can support the high-speed computing demand brought by 5G will be an important issue worthy of attention.
The new generation of battery technology is not yet mature
"Currently, the more mature battery in the 3c market is lithium cobalt oxide, which is also the most widely used cathode material in the consumer electronics market." According to Xia Yongyao, a professor in the Department of Chemistry at Fudan University, the mainstream commercialization currently on the market Lithium battery cathode materials mainly include lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, ternary materials (lithium nickel cobalt manganate, lithium nickel cobalt aluminate), etc. The latter three are mainly demanded in power batteries, and lithium cobalt oxide is more It is used in the field of consumer electronics.
For consumer electronic batteries, Xia Yongyao believes that the input and output performance of lithium-ion batteries mainly depends on the structure and performance of the internal materials of the battery, including negative electrode materials, electrolytes, separators and positive electrode materials. The lithium cobalt oxide battery has the advantages of high specific gravity, high volume and high energy density, so it becomes the best choice for consumer electronic products.
However, with the advent of the 5G era, consumer electronics products continue to introduce new ones, and people’s demand for battery capacity is also rising linearly, requiring battery products with greater flexibility, longer running time, lower cost and higher Security. The characteristics of consumer electronic devices have also put forward more stringent requirements on the new generation of battery technology. The contradiction between continuous miniaturization and battery capacity, and the contradiction between charging and discharging speed and the number of charging and discharging are all issues that need to be resolved.
For enterprises, in addition to working hard on the stability and service life of batteries under the current technical framework, they also need to have a forward-looking awareness of technological revolution and continuously increase the exploration and research of new materials and new battery technologies. Be invincible when 5G comes.
