Watching the giant wheel of time roll forward, the pace of technology has never stopped. Only three years later, solid-state batteries, once unknown in the laboratory, will finally enter the moment when they bloom. The advantages of solid-state batteries are clear: they are denser, safer, and last longer. After this kind of revolutionary innovation and innovation incentive plan is widely used in the market, what kind of impact will it bring to the entire electric vehicle field? Its existence will undoubtedly make the existing lithium-ion battery-powered vehicles look slightly inferior, and even become "old" in the eyes of some people. 
But we probably don't have to be overly depressed. The substitution of technology has always been a double-edged knife. As history has repeatedly proven, every leap and update of science and technology does not always mean that old things become "waste" from now on. They are still able to look at today's society in a different way. For example, while existing electric vehicles may no longer be dazzling in the eyes of solid-state batteries, they have led a low-carbon tourism revolution in the past and will remain an indispensable travel tool for many family businesses for a long time to come. As long as there are values based on human society, they will not become "garbage".
Of course, the mass production of solid-state batteries also shoulders the pressure of rebuilding the electric world. This means that there will be more efficient, safe and environmentally friendly means of transportation in daily life, further improving the urban air index, reducing energy consumption and promoting the sustainable development of society. In the process, we will identify the rise and application of many cutting-edge technologies, as well as the improvement of their living standards, and perhaps the way we all live will also have a disruptive change.
You might as well be a little more open and look further into the future. The progress of science and technology has not only brought about the upgrading of products, but also promoted the progress of civilization. The solid-state battery is just one small step in countless innovations, but it will be a reliable bounce on our way to a better life. The existing electric vehicles, on this leap road, will not become garbage, but a milestone that we must go through, a stepping stone to a more brilliant future. Let's wait and see how technology continues to write new chapters in people's lives in the years to come.
