Abstract Lithium‐ion batteries (LIBs) are extensively used everywhere today due to their prominent advantages. However, the safety issues of LIBs such as fire and explosion have been a serious concern. It is important focus on root causes accidents in mechanisms development. This will enable reasonable control battery risk factors minimization probability accidents. Especially, chemical crosstalk between two electrodes internal short circuit (ISC) generated by various triggers main reasons for abnormal rise temperature, which eventually leads thermal runaway (TR) Herein, this review paper concentrates advances mechanism TR paths: ISC. analyses origin each type path, illustrates evolution TR, then outlines progress strategies recent years. Moreover, offers forward‐looking perspective technologies. work aims enhance community's comprehension behavior categorizing examining pathways induced TR. contribute effective reduction LIBs.

Enabling Ultrastable Co-Free Li-Rich Oxides via TbF₃ Treatment

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(19), С. 25210 - 25220

Co-free Li-rich Mn-based cathode materials (Co-free LRMOs) have become one of the most promising in lithium-ion batteries for next generation due to their low cost, high capacity, and environmental friendliness. Under voltage, redox reactions involving anions can easily lead various issues, including oxygen release, dissolution transition metal elements (TMs), structural collapse these materials. The absence Co element further exacerbates this issue. Here, a simple one-step solid-phase reaction strategy is proposed achieve nanoscale dual modification LRMOs with F Tb doping. has relatively small impact on cell parameters Li+ diffusion ability LRMOs, leading no significant improvement its rate performance. modified only exhibited discharge capacities 220.7, 200.1, 140.0, 115.5, 90.9 mAh·g–1 at 0.1, 0.2, 1.0, 2.0, 5.0 C, respectively. However, exhibit extremely strong stability retain 95.1% initial capacity after 300 cycles, so far, highest retention rates among all Ni/Mn-based Mechanism studies shown that enhancement attributed increased concentration vacancies Ni3+ ions through Furthermore, doping not hinders release O2 but also enhances migration electronic conductivity coefficient LRMOs.
