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.

What are lithium solid-state batteries (SSBs)?

Lithium solid-state batteries (SSBs) are considered as a promising solution to the safety issues and energy density limitations of state-of-the-art lithium-ion batteries.

Are lithium-ion batteries the future of energy storage?

Efficient and clean energy storage is the key technology for helping renewable energy break the limitation of time and space. Lithium-ion batteries (LIBs), which have characteristics such as high energy density, high reversible, and safety, have become one of the great frontiers in the energy storage field .

How long will solid-state batteries last?

Solid-state batteries will emerge as a mature technology in about eight to ten years or so, when their combination of low cost, high energy density/low weight and long life will be ideal for electric vehicle and energy storage applications. What is particularly interesting is that solid-state technology is ideal for a pouch cell format.

How are solid state batteries made?

At a laboratory scale, solid-state batteries based on these materials are usually prepared by compression of the solid-state electrolyte on the composite cathode, either by cold-sintering or hot sintering (see section 3.3), resulting in pellet-type cells.

Are all-solid-state batteries a viable alternative to lithium-ion batteries?

Indeed, dendrite formation in lithium-ion batteries remains a primary failure mechanism. In response to these challenges, all-solid-state batteries (ASSBs) have emerged as a promising alternative, particularly for EVs, by substituting liquid electrolytes with a fully solid counterpart.
