Tokyo University of Technology's Graduate School of Integrated Science and Engineering Graduate School of Integrated Science and Engineering Professor Kenno Koichi's research office, Toyota, and the High Energy Accelerated Research Institute, on March 22, 2016, jointly developed an electrolyte with twice the lithium ion conductivity. Using this electrolyte, a "all-solid ceramic battery" was manufactured. As a result, it was found that its output characteristics were more than three times that of the existing lithium ion secondary battery. There are two types of electrolytes developed this time, all of which are sulphide materials. One is Li9.54Si1.74P1.44S11.7Cl0.3, and the lithium ion conductivity is 25 mS/cm at 27 degrees Celsius, which is very high in the solid electrolyte. In the past, the highest value of the solid electrolyte was the material developed by Professor Toko Ohno in 2011 that was based on Li10GeP2S12 (LGPS) and had a lithium ion conductivity of 12m to 14mS/cm. The other electrolyte is Li9.6P3S12, and its lithium ion conductivity is about 1mS/cm at room temperature, which is comparable to traditional materials, but it can work stably as electrolyte for metal Li, a new candidate material for negative battery cathode. Kanno et al. prototyped all-solid-state ceramic batteries using these materials, and confirmed that their output density was more than three times that of conventional lithium-ion secondary batteries and their energy density was more than twice that of conventional lithium-ion secondary batteries. The output density is the same as or even higher than that of a supercapacitor or an electric double layer capacitor. How to use these two ion-conducting materials and what kind of cathode materials and anode materials are used has not been published. When the temperature is between -30 degrees Celsius and 100 degrees Celsius, the charge-discharge characteristics of this trial battery are 200 to 1,000 times, and the capacity is basically not reduced. In particular, the ratio of the charging capacity to the discharging capacity at each time--charging-discharging efficiency is basically 100% after 1000 times of charging and discharging.
