However, ASSBs still an immature technology and require further advancements on multiple fronts like interface (electro-)chemical and mechanical instabilities.
Electrodes in ASSB require a tight solid-solid contact, rather than a certain porosity in LIB for liquid-state electrolyte to infiltrate. Isostatic pressing is regarded as a promising technology as it can provide three-dimensional force to better achieve material densification.
Solid-state battery cells are hailed as the next big thing in battery technology. Especially for battery electric vehicles, they could significantly increase range, fast charging capabilities and safety. But not all solid-state cells are equal or mature.
What is a solid-state battery?
Based on the conventional LIB concept, the solid-state battery concept aims to replace the liquid electrolyte with a solid electrolyte, Figure 2 (left). This enables the usage of materials with an even higher energy density.
Can all-solid-state batteries improve battery performance?
A pressing need for enhancing lithium-ion battery (LIB) performance exists, particularly in ensuring reliable operation under extreme cold conditions. All-solid-state batteries (ASSBs) offer a promising solution to the challenges posed by conventional LIBs with liquid electrolytes in low-temperature environments.
What is the difference between a lithium-ion battery and a solid-state battery?
Fig. 5. The difference between a lithium-ion battery and a solid-state battery . Conventional batteries or traditional lithium-ion batteries use liquid or polymer gel electrolytes, while Solid-state batteries (SSBs) are a type of rechargeable batteries that use a solid electrolyte to conduct ion movements between the electrodes.
The solid-state battery (SSB) is a novel technology that has a higher specific energy density than conventional batteries. This is possible by replacing the conventional liquid electrolyte inside batteries with a solid electrolyte to bring more benefits and safety.
