Abstract
In recent years, lithium-ion batteries have been used in bulk for the development of new energy vehicles. Studying fault gas adsorption in lithium-ion batteries is crucial to their safe operation. This study constructs and optimizes the adsorption model for fault gases adsorbed on the MgTe monolayer. Analysis of the energy- and electron-related adsorption properties indicates that the MgTe monolayer has a strong adsorption effect on lithium-ion battery failure gases. Meanwhile, the value of Eads increases as the gas coverage expands, with CO showing the greatest increase at 144.79%. Secondly, the conductivity change response of CO adsorption on MgTe is obvious, and the Desorption Time is considerable, indicating its potential as a long-life adsorbent. Furthermore, the Risk Index is defined by the change of Eads (CO), and a strong correlation between the Risk Index and lithium-ion batteries is obtained. This study provides a new idea for lithium-ion battery failure warning and is of great value for the widespread application of new energy.
