Degradation of the performance of Li metal batteries under gamma radiation is linked to the active materials of the cathode, electrolyte, binder, and electrode interface. Specifically, gamma radiation triggers cation mixing in the cathode active material, which results in poor polarization and capacity.
Gamma radiation effects on cathode or electrolyte of Li-ion batteries were studied. Radiation leads to capacity fade, impedance growth, and premature battery failure. Electrolyte color changes gradually after initially receiving radiation dose. Polymerization and HF formation could be the cause of the latent effects. 1. Introduction
The irradiation tolerance of key battery materials is identified. The radiation tolerance of energy storage batteries is a crucial index for universe exploration or nuclear rescue work, but there is no thorough investigation of Li metal batteries. Here, we systematically explore the energy storage behavior of Li metal batteries under gamma rays.
A lingering concern when using lithium ion cells in such radioactive extreme conditions lies in the ability to retain acceptable performance after radiation exposure. The intense radiation environment may degrade the properties of the electrode and electrolyte materials quickly, significantly reducing the battery performance.
The intense radiation environment may degrade the properties of the electrode and electrolyte materials quickly, significantly reducing the battery performance. The latent effects due to radiation exposure can also result in long term battery failures.
NCM811||Li batteries have the best tolerance to irradiation, with decreasing values of capacity retention following gamma irradiation for LFP||Li, NCM811||Li, and LCO||Li batteries of 18.9%, 21.3%, and 23.9%, respectively.
