Favorable composite electrodes for all-solid-state batteries

Battery Materials for All - Solid State Batteries

The Grey group tackles a broad range of materials science and energy storage challenges that include various aspects of solid state chemistry, spectroscopy, and theoretical studies. To understand and control the materials that are desirable for energy storage applications, we use a suite of synthetic and analytical techniques, including diffraction, microscopy, solid state NMR, and computation....

Metal hydride-based materials towards high performance negative electrodes for all-solid-state lithium-ion batteries.

Electrode performances of MgH2-LiBH4 composite materials for lithium-ion batteries have been studied using LiBH4 as the solid-state electrolyte, which shows a high reversible capacity of 1650 mA h g(-1) with an extremely low polarization of 0.05 V, durable cyclability and robust rate capability.

Compatibility issues between electrodes and electrolytes in solid-state batteries

Remarkable success has been achieved in the discovery of ceramic alkali superionic conductors as electrolytes in solid-state batteries; however, obtaining a stable interface between these electrolytes and electrodes is difficult. Only limited studies on the compatibility between electrodes and solid electrolytes have been reported, partially because of the need for expensive instrumentation and...

All-Solid-State Lithium Batteries with Wide Operating Temperature Range

Lithium ion secondary batteries have a high voltage and a high energy density, as shown in Fig. 1, and are widely used in mobile devices such as cell phones, notebook PCs and PDAs. However, since lithium ion secondary batteries use a flammable organic liquid electrolyte, there is a risk of explosion or fire. Fire accidents can also occur due to contamination during production or from overchargi...
