Solid-state batteries move from dream technology to reality as QuantumScape, Toyota, CATL jockey

Solid-state batteries, seen as a next-generation technology for electric vehicles and energy storage systems, are reigniting a commercialisation race. They replace liquid electrolytes with solid materials to cut fire risk and raise energy density, but face hurdles including dendrites, manufacturing defects and high costs. QuantumScape says it has secured key manufacturing technology. Toyota and CATL are also stepping up development, while some companies weigh aviation and defence as early markets.

BYD speeds up solid-state battery commercialisation, first fitment in 2027 and mass production around 2030

BYD will unveil its first vehicle fitted with a solid-state battery in 2027, but has not disclosed the model or mass-production schedule. Executive Vice President Stella Li said BYD is in a leading position in both technology and commercialisation and will introduce one model using the technology in 2027. The plan aligns with a roadmap presented by FinDreams CTO Sun Huajun, which targets demonstrations from 2027 and large-scale production around 2030.
