How to improve the performance of the battery?

The basic principle of today's batteries is the same as that of voltaic batteries decades ago, and they are used through redox reactions. As long as your high school chemistry class did not miss the electrochemistry lesson, you can basically know that more than 80% of Li Jie’s battery principle. The ZnCu primary battery described in the high school chemistry book uses hydrogen ions. The principle is the same as the current lithium battery, but the positive The anode material and electrolyte are exchanged, and hydrogen ions are exchanged for lithium ions. Simply put, what factors determine the size of the battery capacity? Battery capacity x battery voltage u003d battery energy density x battery volume. The battery volume is affected by these aspects. One is the size of the whole machine, the other is the thickness of the fuselage, and the other is some detailed design. These factors have brought restrictions on the volume of the battery, therefore, determine the size of the battery. The factor is battery energy density + battery volume. In theory, there are two ways to improve the performance of the battery, one is the energy density of the new battery, and the other is the volume of the new battery. However, this is only a theoretical level. In real life, the size of smart phones is getting smaller and smaller, and the space left for batteries is correspondingly limited. Adding the volume of the battery doesn't work. Is it possible to go the other way to increase the energy density of the battery? In theory, it is possible, but the reality is that once the energy density of the battery rises to a certain threshold, the battery itself will become an explosive, and its safety becomes a very serious problem. For example, all kinds of high-capacity power banks are not allowed to be charged in confined spaces such as airplanes and subways to prevent safety accidents, and this is a real lesson. Once the above-mentioned carbon nano supercapacitor batteries can be successfully launched and commercialized on a large scale, the above problems will be solved, which will bring disruptive changes to the traditional electric vehicle industry, smart phone industry and social-related industries. Finally, I would like to mention a personal idea about battery development. In fact, if battery technology is limited by various factors and cannot make a breakthrough, there is actually another way to go wireless power supply technology. If one day, the power supply can be the same as today's wifi. If the device is used for power supply (I call it power cloudification), then the capacity and energy density of the battery itself are not so important anymore, just like the popularity of cloud computing, the local small server is no longer important.
