Chinese sodium-ion battery matches Tesla on build quality, teardown finds
1 min read
A teardown of Hina's sodium-ion battery found cell-to-cell resistance varying by just 5.3% across 120 cells, matching Tesla's lithium-ion manufacturing quality. The cell uses a tabless, double-aluminum current collector design similar to Tesla's 4680 cell. It trails lithium-ion on energy density and low-temperature performance.
