## Description

- description: The increasing energy density and size requirements have necessitated  the
    establishment of reliable safety technologies for rechargeable  batteries. In
    particular, understanding and controlling thermal runaway,  an uncontrollable
    heat generation from continuous exothermic reactions  in batteries, is essential
    for developing high-safety batteries. However,  comprehensive safety evaluations
    at the full-cell level are limited by  size requirements (greater than the ampere-hour
    scale) for performing  accelerating rate calorimetry tests that can provide critical
    information on  heat generation during thermal runaway. Further, efficient safety
    screening  is difficult because of substantial quantities of battery materials
    and costly  manufacturing processes. Here we designed cylindrical pouch-type small  batteries
    (~21 mAh, ~0.1 g of cathode active materials) that are highly  susceptible to
    heat generation, thus allowing us to perform full-cell-level  accelerating rate
    calorimetry tests on a laboratory scale. This enables rapid  safety screening
    and early-stage feedback for battery design, which can help  accelerate the development
    of high-safety batteries.
