lithium battery technology develops slowly. How to face the future?
in the past seven years, mobile phones have completed the transformation from functional machines to smart machines, and the role of mobile phones in life is becoming more and more important. However, the development of mobile phones is changing with each passing day, and the performance has been developed by leaps and bounds. Only the battery technology has been developing slowly, which has also become an important reason restricting the further development of mobile phones.
development history and current situation
Lithium batteries were first used in cardiac pacemakers. The advantages of lithium battery, such as extremely low self discharge rate and flat discharge voltage, enable the pacemaker implanted into the human body to operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, which is more suitable for integrated circuit power supply.
Sony successfully developed lithium ion batteries in 1991. Its commercialization greatly reduces the weight and volume of people's portable electronic devices such as mobile phones, notebooks and calculators. However, after nearly two decades of development, whether it is smart phones, tablets or today's extremely popular Tesla electric vehicles, the lithium battery technology used in all electronic devices is not fundamentally different from the lithium-ion battery developed by Sony in that year. Lithium battery technology seems to have entered a dead end, from the promoter of the electronic industry to the regulator of the industry.

however, do not be blindly pessimistic. In the past two decades, lithium battery technology has not completely stagnated. After years of technological development, lithium battery technology has made considerable progress. Especially in terms of charging efficiency, battery capacity, heating and cooling, the traditional lithium battery has also performed better and better. In addition, with the rise of the electric vehicle industry, it will accelerate the technological innovation and development of lithium battery, but it still needs to wait for revolutionary changes.
