Solid-state batteries also have 'Bugs'!

At present, all solid-state batteries still need to solve three problems at the technical level: The first is ionic conductivity: (Conductivity is a parameter used to describe the ease of charge flow in a substance. In a battery, the function of the electrolyte is to charge and discharge the battery. In the process, a transmission channel is built for lithium ions between the positive and negative electrodes to realize the conduction of the internal current of the battery. The indicator that determines the smooth transportation of lithium ions is called ion conductivity.) Will the power battery revolution really come? How far is solid-state batteries from us? The three classification systems of solid electrolytes are mentioned above, but in general, no matter what kind of polymer system, the ionic conductivity is much lower than that of liquid electrolytes. The biggest difference is that one liquid conducts electricity and the other is solid state conduction, so the pass rate of lithium ions determines the smoothness of the mutual transportation of the positive and negative electrodes to a certain extent. The second point is the solid-to-solid contact between the solid electrolyte and the positive and negative electrodes. The contact area is small and the compact type is much worse. At present, most products still need to add liquid electrolyte to alleviate the impedance effect of the interface and increase the conductivity to a certain extent. Will the power battery revolution really come? The third point of how far solid-state batteries are from us is cost. Because of the high technical difficulty of solid-state batteries, the processing efficiency is very low, resulting in high cost, which is about several tens of times that of ternary lithium-ion batteries. It can not be applied on a large scale. It can be regarded as a major disadvantage of solid-state batteries. The car is not a supercar, but a model that will become the mainstream in the future. Will the power battery revolution really come? How far is solid-state batteries from us? State Comment: Will the power battery revolution really come? How far is solid-state batteries from us? Will the power battery revolution really come? How far is solid-state batteries from us? At present, solid-state batteries have not achieved large-scale processing and application. Everything is only the initial test stage and large-scale commercialization has not been implemented. Solid-state batteries can be said to have a wide range of advantages, but the biggest shortcoming price and essential technical difficulties have not been solved. However, for this brand-new product, there are Toyota Motor, LG Chem, Samsung SDI, and the Ningde era and China. Lithium battery companies such as Xuan Hi-Tech and Honeycomb are participating in the research of solid-state batteries, and it is only a matter of time to overcome the difficulties. Will the power battery revolution really come? How far is the solid-state battery from us? At present, Toyota and Volkswagen are the leading car companies in the field of solid-state battery layout among the car companies; in China, Guoxuan High-tech will start to carry out solid-state battery technology in 2022. Iterative upgrades, processing high-safety solid-state batteries, and all solid-state batteries with an energy density of more than 400Wh/kg will be processed in 2025. We will wait and see for this.
