A leading EV battery pack assembler experienced catastrophic failure when 15Ah 21700 packs overheated during fast charging, traced to high-resistance nickel-plated steel H-strips that created 85mΩ cell-to-cell connections triple the target 25mΩ specification.
Production halted, $2.3M inventory scrapped, and warranty claims mounted until switching to 99.6%+ pure nickel H-type strips reduced resistance to 22mΩ, eliminated thermal runaway risks, and achieved 98% first-pass yield.
This failure underscores why OEMs, fabricators, and procurement managers specify pure nickel H-type strips for 21700 packs when reliability not lowest cost determines long-term success in chemical processing, power generation, marine, and EV applications.
