Solid-state batteries, referred to as “the pearl of the crown” due to their theoretical energy density of up to 400 Wh/kg and superior safety characteristics, are leading the transformation of battery technology.
Global market landscape
In terms of technological routes, fierce competition is unfolding among China, Japan, South Korea, and the United States and Europe. Japan and South Korea started early, mainly adopting sulfide solid electrolyte routes, while the US and Europe prefer polymer and oxide solid electrolytes.
China’s strategy is multi-faceted, focusing on the oxide area while actively developing semi-solid batteries to adapt to existing industry transformation needs.
Technological bottlenecks and challenges
Despite the broad prospects for solid-state batteries, the industrialization process faces numerous challenges. Among these, the cost issue is particularly prominent, with solid-state battery costs being approximately 1.5 times that of traditional lithium-ion batteries at about $160.
Moreover, performance issues persist, such as slow charging and discharging speeds, volume expansion during charge-discharge cycles, and interfacial resistance issues at solid-solid interfaces, which require the development and optimization of new solid-state electrolyte materials.
In terms of supporting facilities, the solid-state battery supply chain is still being integrated, lacking standardized production equipment and testing methods. Additionally, the diversity of various solid-state battery technology routes has led to inconsistent testing standards, undoubtedly increasing the technical risks facing the industry.
Market penetration and technology evolution
It is expected that by 2030, the market size of solid-state batteries will reach 17.2 billion yuan, with significantly increased product penetration rates. The technology pathway for solid-state batteries can be expressed as a “three-step approach”: first, from 2015 to 2025, utilizing hybrid solid-liquid batteries as a transition.
Secondly, by 2030, solid-state batteries are expected to achieve a penetration rate of 12% in consumer batteries; ultimately, by 2040, a full-scale transition to an “all-solid-state era” is anticipated.
In the field of power batteries, with the expansion of the new energy vehicle market, the penetration rate of solid-state batteries is expected to reach 10%. According to relevant policies, by 2027, the market share of new energy vehicles will increase significantly, further driving the demand for solid-state batteries.
