LR1130 battery technology progresses with insufficient advantages in charging and lifespan

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 solid-state batteries, including information on the charging efficiency and lifespan of solid-state batteries. Unfortunately, the conclusion shows that this new battery technology does not have a clear advantage over current lithium battery technology.

This research report claims that the charging efficiency of solid-state batteries is not much higher than that of current lithium batteries. At the same energy density, the charging time of solid-state batteries is also about 1 hour, but current lithium batteries also have the same charging efficiency. In addition, in terms of battery life, solid-state batteries 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 solid-state batteries absorb ions more efficiently. Although the current charging efficiency is not ideal, there is still room for development.

The specific energy density of solid-state batteries was not mentioned in the report, but it is also the aspect that the industry is most concerned about. According to previous reports, the energy density of solid-state batteries 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, LR1130 battery technology is still the most concerned development direction in the world.
