Which gas can batteries emit that is highly explosive?

Explanation:
When batteries operate, especially certain chemistries, hydrogen gas can be generated and vented. Hydrogen is highly explosive in air because it forms flammable mixtures across a wide range of concentrations (roughly 4% to 75% hydrogen in air). It’s also colorless and odorless, so leaks can build up quietly unless there’s good ventilation or detectors. Oxygen, while it supports burning, isn’t explosive by itself. Argon and nitrogen are inert gases and don’t participate in explosive reactions under normal conditions. So hydrogen is the gas from batteries that poses a high explosion risk.
