Solid State Progress Reduces Electrical Resistance Between Cathode, Electrolyte

Researchers at the Tokyo Institute of Technology and Tohoku University have developed a safer and higher-performing solid state battery by reducing electrical resistance at the electrode/solid electrolyte interface. When electrical resistance is high, heat is produced and charging and discharging are slowed. The Japanese researchers, led by Professor Taro Hitosugi, created a series of thin-film layers between the cathode material and the solid electrolyte that dramatically reduce the electrical resistance at the interface, Design News reports. The research was published last month in ACS Applied Materials and Interfaces (DOI:10.1021/acsami.8b08506).
