A method and a system for predicting battery thermal runaway, and a storage medium are provided. The method includes: obtaining voltage data of a battery to be tested under a preset condition; obtaining internal resistance data of the battery to be tested according to the preset condition and voltage data; processing the internal resistance data based on a preset activation energy model to obtain activation energy data of the battery to be tested; and determining a thermal runaway probability of the battery to be tested according to the activation energy data, thereby achieving accurate prediction of thermal runaway of the battery to be tested.

Provided are a battery cell and a battery pack. The battery cell includes a core, a housing, an explosion-proof valve and a first bracket. The core is disposed in the housing, and the explosion-proof valve is disposed at a bottom of the housing. The first bracket is disposed in the housing, and the core is disposed on the first bracket. The first bracket is provided with a first through hole, the first bracket and the bottom of the housing are enclosed to form an accommodation space, the explosion-proof valve is located in the accommodation space, and the first through hole communicates with the accommodation space so that gas generated by the core may flow into the accommodation space via the first through hole.
