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.

Why are solid-state batteries important?

Solid electrolytes, which enable solid-state batteries, provide great levels of safety and energy density . Electrolytes must concurrently satisfy several criteria, including ion transport, electron insulation, and stability against the extreme chemical natures of electrodes, in order to enable new battery chemistries .

Are solid-state lithium batteries a next-generation energy storage technology?

Recently, solid-state lithium batteries (SSLBs) employing solid electrolytes (SEs) have garnered significant attention as a promising next-generation energy storage technology.

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].

What makes a battery a solid state battery?

2. Solid Electrolytes: The Heart of Solid-State Batteries The gradual shift to solid electrolytes has been influenced by the prior development of conventional lithium (Li) batteries, which have traditionally employed liquid electrolytes.

When did electric vehicles start using solid state batteries?

In 2011, Bolloré of France introduced the first commercialize solid-state batteries for electric vehicles with only approximate 100 Wh/kg energy density. 5 years later, another solid-state electrolyte lithium metal battery was introduced by America Solid Energy Company reached 300 Wh/kg.
