The Solid Foundation of Solid-State Batteries

Solid state batteries (SSBs) are defined as batteries that use a solid-state electrolyte (SSE) as their iconic conductor between the anode and cathode.

With decades of development and evolution, lithium-ion batteries are popular today and used in a wide range of applications. However, most lithium-ion batteries in the market now use liquid electrolytes, a mixture of multiple organic compounds that are inherently flammable and unstable under raised temperatures. In recent years, dangerous incidents involving personal injuries and property damage have occurred in products such as earbuds, cell phones, electric vehicles (EVs) and battery energy storage systems. Conventional lithium-ion battery technology has shown its limitations and raised energy density and safety concerns.

As a result, SSBs are considered the most promising next-generation battery. They offer high performance and the possibility of improved safety at a low cost.

Our e-book covers the advantages and challenges of SSBs, and ways to mitigate risks associated with this battery technology.
