Hmn-372 [FRESH]
The (often colloquially called "Hamecchu") is one of Honnaka's flagship lines. Key characteristics include:
Charging a high‑capacity cathode expands the lattice (≈ 5 %). In HMN‑372, the flexible graphene scaffold absorbs ≈ 70 % of the volumetric strain, preventing crack formation in the NCM nanosheets. In‑situ X‑ray tomography after 2 000 cycles shows < 0.5 % micro‑cracking compared with > 5 % in control cells. HMN-372
