Solid-State Battery
A next-generation battery technology that uses a solid electrolyte to replace conventional liquid electrolytes. It theoretically offers higher energy density and safety, but scientific and engineering bottlenecks remain in lifespan, charging performance and cost.
Timeline (last 90 days)
The core change in solid-state batteries is replacing the liquid electrolyte in traditional lithium-ion batteries with a solid electrolyte, which is non-flammable and resistant to high temperatures and can in theory improve both safety and energy density.
The commercialization of solid-state batteries faces two major engineering bottlenecks: first, interfacial impedance causes a drop in ion transport efficiency; second, material stability issues, as some solid electrolytes undergo side reactions with the electrodes during repeated charge and discharge or decompose under high voltage.
Liu Zhimin expects that solid-state batteries will only gradually gain penetration in the passenger car segment after 2032, and even then penetration may be below 1%.
Solid-state batteries have a theoretical energy density of 400–500 Wh/kg, and the industry expects large-scale commercialization may still require 5–10 years.
