Therefore, this paper proposes a novel leasing pricing mechanism towards flexible energy storage application for DNs and ESS. Firstly, an optimal bidding model considering both energy and frequency regulation (FR) markets is developed for ESS to assess potential market revenues. Then, a robust optimization scheduling model of DNs with the leased ES is formulated to ensure the safe and economic operation under uncertainties. Furthermore, a PSO-Nash bargaining-based cooperative game model is proposed to determine both the optimal leased capacity and price between DNs and ESS, achieving a win-win solution between the two subjects.

Most research currently focuses on external passive firefighting after thermal runaway. To mitigate fire and explosion risks caused by rapid energy release in the micron-scale spaces of battery electrodes, a novel self-adaptive microcapsule has been proposed. The designed hydrated microcapsule consists of a melamine-urea-formaldehyde resin shell and a core material of Ba(OH)<sub>2</sub>·8H<sub>2</sub>O. Once the temperature exceeds 120 °C, the organic shell ruptures and releases the encapsulated core material. The hydrated core material can preemptively consume the lithium-embedded graphite on the negative electrode, thereby modulating the timing of the thermal runaway chain reaction to mitigate the hazards associated with thermal runaway in lithium-ion batteries. Differential scanning calorimetry results indicate that only 4 g/Ah of the microcapsules can reduce the total reaction enthalpy by 24.61 %. Cycling tests show that the battery assembled with the microcapsule achieves a capacity retention rate of 97.33 % after 225 cycles at a charge rate of 1/3C and a discharge rate of 1C. Accelerating rate calorimeter tests indicate that the maximum temperature during thermal runaway has been reduced by 106.2 °C.
