Solid-state battery positive electrode technology roadmap

What is a solid-state battery roadmap?

Based on an extensive literature review and an in-depth expert consultation process, the roadmap critically evaluates existing research as well as the latest findings and compares the development potential of solid-state batteries over the next ten years with that of established lithium-ion batteries.

What is the role of electrode morphology in solid state batteries?

In the field of solid state batteries, there is an emerging opportunity to explore the changes in electrode and electrolyte morphology; for example, to track the growth of metallic dendrites leading to short circuit, or changes in the electrode/electrolyte interface.

How to design a solid-state battery?

To design solid-state batteries which optimise specific energy and longer life, it is important to understand the processes happening at the interface between the solid electrolytes and cathodes, and to adopt rational approaches to solve the problems causing cell degradation.

What are the three steps in the manufacturing process of solid-state batteries?

The three steps for the manufacturing process of solid-state batteries are the electrode and electrolyte separator produc-tion, the cell assembly and the cell finishing .

Can X-ray imaging improve the development and commercialisation of solid state batteries?

Advances in science and technology to meet challenges The growth in maturity of x-ray imaging technologies, and their flexibility as part of a portfolio of correlative characterisation techniques, provides a compelling opportunity to enhance the development and commercialisation of solid state batteries.

What is a solid-state battery?

Solid-state battery mainly consists of a solid electrolyte separator, anode and cathode active materials. The most promising anode active materials to achieve high energy density are lithium metal and silicon.
