Technical progress of button battery 2025

According to foreign media reports, the German Institute for Energy and Climate Research recently released a paper that mainly mentioned the research and development progress of button battery 2025, including information on the charging efficiency and life of button battery 2025. Unfortunately, the conclusion shows that this new battery technology does not have a clear advantage over the current lithium battery technology.

This research report claims that the charging efficiency of button battery 2025 is not much higher than that of current lithium batteries. At the same energy density, the charging time of button battery 2025 is also about 1 hour, but the current lithium batteries also have the same charging efficiency. In addition, in terms of battery life, button battery 2025 can still maintain 84% of their service life after 500 full charge and discharge cycles, and the data is basically consistent with current battery technology. However, the report also mentioned that the electrodes in button battery 2025 absorb ions more efficiently. Although the current charging efficiency is not ideal, there is still room for development.

The report did not mention the specific energy density of button battery 2025, but it is also the aspect that the industry is most concerned about. According to previous reports, the energy density of button battery 2025 will be three times that of lithium-ion batteries. According to the technical goals of "Made in China 2025", the energy density of lithium battery cells will reach 300Wh/kg by 2020 and 400Wh/kg by 2025. Therefore, solid-state battery technology is still the most concerned development direction in the world.
