Are solid-state batteries the future of vehicle electrification?

Solid-state batteries (SSBs) are expected to play an important role in vehicle electrification within the next decade. Recent advances in materials, interfacial design, and manufacturing have rapidly advanced SSB technologies toward commercialization.

Could solid-state batteries revolutionize the EV landscape?

Solid-state batteries (SSBs), characterized by their use of solid electrolytes (SEs) instead of volatile/flammable liquids (Figure 1), could revolutionize the EV landscape. SSBs offer significantly enhanced energy densities if they utilize high-specific-capacity electrodes, including Li metal or alloys.

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.

Should Europe develop a competitive lithium-ion battery?

To avoid relying on other countries to meet its energy transition goals, Europe is faced with the challenge of developing and producing competitive lithium-ion (Li-ion) batteries. While a promising option, Li-ion technology stills needs further development in order for mass production to be economically viable and environmentally friendly.

What is a hybrid solid-state battery?

Interestingly, there are a wide range of different materials and approaches being developed in parallel, without a clear winner. One of the approaches that has been adopted by several companies is a hybrid solid-state battery, where a dense solid separator is used, but the cathode interface is aided by the use of a liquid or gel (Figure 1 b).

How to promote sustainable additive manufacturing in battery production?

The development of standards for powder reutilization, quality control, and certification will be crucial to promote sustainable additive manufacturing in battery production. As the demand of SSBs grows, so does the need for sustainable processing methods that mitigate environmental impact and promote eco-friendly manufacturing practices.
