Extended battery life, resource conservation, and environmental protection may all be achieved by efficiently using retired LIBs, which still have between 70 and 80 % of their original capacity. This paper first examines the life cycle of a LIBs using End of Life (EOL) and Remaining Useful Life (RUL) prediction techniques. In accordance with the predicted RUL and EOL prediction, we suggest an efficient 5R strategy for lithium-ion battery recovery, reuse, repair, remanufacture, and recycling.

This paper explores a novel phase change energy storage concrete by encapsulating capric acid-myristyl alcohol (CA-MA) within hollow steel balls (HSB) to create PCM-HSB aggregates. Graphite powder (GP) was added as an admixture to enhance thermal conductivity. The thermal performance and mechanical properties of GP/PCM-HSB concrete were tested at various replacement ratios: PCM-HSB (10.0 %, 12.5 %, 15.0 %) and GP (2.5 %, 5.0 %, 7.5 %, 10.0 %). Results indicated that as the PCM-HSB replacement ratio increases to 15.0 %, the specific heat capacity of the concrete increases by 61.9 %, enhancing its heat storage capacity and enabling the concrete to better maintain a stable internal temperature as temperature changes. The addition of GP has a positive impact on the thermal conductivity. When the GP content increases to 5.0 %, the thermal conductivity of the concrete increases by 60.4 %, effectively solving the problem of the decrease in thermal conductivity caused by the addition of PCM-HSB. The advantage of GP/PCM-HSB is that it encapsulates the phase change material inside the hollow steel balls, which can effectively prevent the leakage of the phase change material and improve the stability and durability of the material. At the same time, it can store and release heat efficiently during the phase change process, enhancing the energy storage capacity of the concrete. The addition of graphite powder (GP) significantly increases the thermal conductivity of the concrete. The best-performing mix ratio was identified as 15.0 % PCM-HSB and 5.0 % GP.

The results showed that, during the process of five intermittent heat storage cycles, the pile top extended upward, the additional compressive axial force was exerted on each part of the pile, and the pressure between pile and soil increased. The rest period in the cycle could alleviate the thermal-structural responses. However, the alleviating effect was gradually weakened.

This work investigates the suppressive effect of Novec-1230 on the fire induced by overcharging in a 3P4S lithium iron phosphate (LFP) battery module. The surface temperature, module voltage, temperature rise rate, temperature distribution in pack, total voltage, extinguishing process, battery wreckage, and real-time changes in gas concentration were determined. During the suppression process, Novec-1230 can effectively reduce the surface temperature of the battery without TR, and the cooling rate is up to −0.39 °C/s. For the battery that has started the TR, Novec-1230 cannot inhibit the chain reaction inside the battery. When Novec-1230 is released, the battery temperature still initially rises, but the temperature rise rate is significantly reduced. Once the heat generation of the battery gradually reaches a balance point with the heat absorption from the vaporization of Novec-1230 in its liquid state, the battery temperature begins to decline, the entire fire suppression process lasted for 81 s. After the flame is extinguished, the concentration of combustible gases begins to rise sharply, with the concentrations of H<sub>2</sub> and CO reaching 1078 ppm and 164 ppm, respectively.
