A study in Cell Reports Physical Science confirmed that Hina’s commercial sodium-ion battery matches the performance and production quality of Tesla’s lithium-ion batteries.
Sodium-ion technology offers cheap, abundant materials derived from salt, eliminating the need for rare and conflict-ridden minerals like lithium, cobalt and nickel.
The Hina battery, available in a 9.8 kWh unit, boasts a 95% round-trip efficiency and a 6,500-cycle lifespan, outperforming most lithium-iron-phosphate batteries with superior thermal stability.
Despite its advantages, the Hina battery struggles to charge effectively at sub-zero temperatures and shows unexpectedly high, unevenly distributed levels of copper in cathode regions.
Researchers are optimistic about overcoming these hurdles, planning to focus on improving low-temperature charging and optimizing carbon-based anodes and electrolyte formulations.
In what could be a seismic shift in the global energy storage landscape, a groundbreaking new study published in Cell Reports Physical Science has confirmed that a commercial sodium-ion battery produced by Chinese company Hina matches the performance and production quality of Tesla;s vaunted lithium-ion batteries.
