Abstract

In order to reach the peak in carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060, it is necessary to perform technical research to reduce carbon emissions. Key core technologies such as zero emissions/reductions, hydrogen industry, and energy storage are particularly important in energy conservation and emissions reduction. In terms of energy storage, lithium-ion batteries (LIBs) are more advanced. However, traditional LIBs have risks such as swelling, leakage, and flammability. The creation of solid-state lithium-ion batteries (SSLBs) will be thoroughly described in this article, along with the benefits and drawbacks of various electrolytes and electrode materials. Additionally, the future development prospects of SSLBs will be discussed. In the long run, with the continuous optimization of SSLBs performance, the positive electrode material system is a higher specific capacity of lithium-rich materials, and the lithium-ion batteries with negative metal lithium will become mainstream, and the SSLBs technology with a higher energy density, lower cost, more security, and better stability will play a vital supporting role in the clean energy transformation.
