Key technological breakthroughs in solid-state batteries

What research should be done on solid-state battery technology?

Research should focus on developing standardized testing protocols to evaluate and compare the safety profiles of various solid-state battery technologies.

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.

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.

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.

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.

Can solid-state batteries overcome the safety issues of liquid electrolytes?

Solid-state batteries (SSB) may overcome the safety issues of liquid electrolytes due to the adoption of solid-state electrolytes [ 1 ]. New types of solid electrolytes have triggered a surge in SSB development [ 3 ].
