- Giant Manufacturing will unveil the first electric bicycle powered by a semi-solid-state battery, claiming it as an industry first with a new 'smart power bike' design
- T&D developed the production-destined semi-solid-state e-bike batteries, having been spun out of Bafang and founded by Bafang co-founder Sunny He
- Semi-solid-state batteries replace most liquid electrolyte with a gel-like or solid component, offering higher energy density and improved safety over traditional lithium-ion cells
- Bafang is connected to the innovation through Sunny He, who co-founded both Bafang and T&D, the company behind the new battery technology showcased at EICMA 2025
Why it matters: E-bike battery innovation has largely stalled around conventional lithium-ion chemistries, so Giant’s move gives it a technical edge in a competitive market. The shift to semi-solid-state systems could extend range and reduce fire risk, benefiting riders and setting a new benchmark for battery performance.
