Solid-state battery technology research and development process

Are solid-state batteries the future of energy storage?

Solid-state batteries are widely regarded as one of the next promising energy storage technologies. Here, Wolfgang Zeier and Juergen Janek review recent research directions and advances in the development of solid-state batteries and discuss ways to tackle the remaining challenges for commercialization.

What is a solid-state battery?

Currently, in particular the automotive industry is focusing on the solid-state battery for electric vehicles. New materials and manufacturing processes are needed for the development of rechargeable batteries based on solid-state technology, in which solid instead of liquid electrolytes are used.

Why do we need a solid state battery?

The electrolyte is a priority area of technology development, and the advances in developing solid-state batteries are perfecting conductivity, reducing interfacial resistance, and improving density and stability. By contrast, the opportunities are to reduce cost, prevent short circuits, and prolong the life cycle.

Are solid-state batteries a viable follow-up technology?

As one of the more realistic advancements, the solid-state battery (SSB) recently emerged as a potential follow-up technology with higher energy and power densities being expected, due to the possibility of bipolar stacking, the potential usage of the lithium metal or silicon anode and projected higher device safety.

Why are solid-state lithium-ion batteries (SSBs) so popular?

The solid-state design of SSBs leads to a reduction in the total weight and volume of the battery, eliminating the need for certain safety features required in liquid electrolyte lithium-ion batteries (LE-LIBs), such as separators and thermal management systems [3, 19].

Is solid-state lithium battery the future of Automotive Power Battery?

The solid-state lithium battery is expected to become the leading direction of the next generation of automotive power battery (Fig. 4‐1) . In this perspective, we identified the most critical challenges for SSE and pointed out present solutions for these challenges.
