At the CLNB 2025 (10th) New Energy Industry Chain Expo - All-Solid-State Battery Forward-Looking Technology Forum hosted by SMM Information & Technology Co., Ltd. (SMM), Dr. Roberto C. Dante, PhD, Chief Research Officer, and CEO of 2Dto3D, shared insights on the topic of "Zirconate Perspective as a Solid-State Electrolyte."
Solid state batteries (SSB)➟solid electrolytes (SE)
Solid electrolytes, as the core of solid-state batteries (SSBs), play a crucial role in determining the kinetics of ion transport and the interface compatibility with cathodes and anodes, which can be subdivided into catholytes, bulk electrolytes, and anolytes based on their functional characteristics.
Advantagesof SSB
Increased safety due to absence of flammable and toxic liquids
Environmental friendly
Long life (> 10,000 Cycles）
Fast charging
Higher temperature work
Higher voltage individualcells due to easier bipolarstacking
Higher voltagee cells dueto highervoltagecathode
Inorganic solid electrolytes have advantages over polymer electroltes in terms of thermal stability ionic conductivity and electrochemical windows.
Disadvantages of SSB
Li-dendrites and cracks
Stabilization of interfaces
the reliance of ionic diffusion on contact of solid particles
Stresses due to electrochemical cycling can lead to cracks at solid interfaces
