Outside China people think solid state battery is a new new thing that will defeat China...but inside China solid state battery already coming into production
The current problem on solid state battery is it cannot be mass produce yet and the solid electrode is brittle and crack during rough driving
Firstly, one of the most significant challenges lies in the manufacturing process. Solid-state batteries replace the liquid or gel electrolyte found in lithium-ion batteries with a solid one. This shift in material requires a complete overhaul of the manufacturing process, demanding significant investment in new production equipment and facilities. Additionally, the solid electrolyte’s sensitivity to moisture and air necessitates stringent environmental controls during production, further escalating costs.
The second pitfall revolves around the issue of energy density. While solid-state batteries theoretically offer higher energy density, achieving this in practice has proven to be a daunting task. The interface between the solid electrolyte and the electrodes poses a significant challenge. This interface must be perfectly seamless to allow for efficient ion transport, a feat that is difficult to achieve with current technology. Any imperfections can lead to increased resistance, reducing the battery’s overall energy density.
Thirdly, the durability of solid-state batteries is another area of concern. While they are touted for their long life spans, the reality is that solid-state batteries can degrade over time. The stress caused by repeated charging and discharging cycles can lead to the formation of cracks in the solid electrolyte, impairing the battery’s performance. Moreover, the solid electrolyte’s brittleness can lead to mechanical failures, further compromising the battery’s longevity.
Lastly, there’s the issue of temperature sensitivity. Solid-state batteries operate optimally at high temperatures, which is not ideal for many applications, particularly electric vehicles. Operating these batteries at lower temperatures can result in poor ion conductivity, leading to reduced performance. Therefore, additional systems may be needed to maintain optimal operating temperatures, adding to the complexity and cost of the overall design.

sure or not........
u want to make money, u must have an opinion and put money where the mouth is. talk no use, action speaks louder than words.
