" CATL has thrown its hat into the ring with the Naxtra sodium-ion battery, with 175 Wh/kg and 10,000 lifetime cycles along with operation from -40°C to 70°C. CATL is planning a start-stop battery for trucks using the technology. It has the potential to replace lead-acid batteries. CATL has announced battery pricing at the cell level in volume at $19/kWh.

    The batteries have gotten better over time, but they can still fail fairly early

    Aside from the OG Nissan Leaf with passive cooling, this really seems like more of a scare tactic than an actual issue.

    I don’t know about all EVs, but assuming they’re similar to mine:

    • battery warranteed for 8 years, 120,000 miles
    • solid history of batteries lasting 250,000 miles or more
    • aside from accident or manufacturing defect, batteries rarely actually fail. The above are defined for battery health being above 80%

    I’m sure it happens that a few people need to replace the battery but they tend to last beyond the full expected lifetime of most cars and the usual failure mode is to continue working with less range
