Material synthesis, physical and chemical properties. Traditionally lithium metal anode needs to be heated above 200℃ to get melted (as shown in Fig. 1 a), such that any battery with liquid alkali metal anode needs to operate at a high temperature, which consumes a lot of energy and is extremely dangerous. In contrast, the preparation of liquid lithium solution (Li-BP

There are abundant electrochemical-mechanical coupled behaviors in lithium-ion battery (LIB) cells on the mesoscale or macroscale level, such as electrode delamination, pore closure, and gas formation. These behaviors are part of the reasons that the excellent performance of LIBs in the lab/material scale fail to transfer to the industrial scale.

In this work, the dynamic pressure conditions of 101 kPa, 70 kPa, and 40 kPa and ambient temperatures of −15 °C, 0 °C, and 25 °C were selected. Some critical parameters of lithium-ion batteries, such as temperature variation, mass loss, and heat distribution, were obtained.
However, the ambient pressure, which is directly associated with the oxygen concentration, also shows a pronounced effect on the thermal runaway process. Chen et al. utilized in-situ calorimeters in Hefei (pressure, 100.8 kPa) and Lhasa (pressure, 64.3 kPa) to assess the thermal and fire hazards of lithium-ion batteries.

The ever-increasing demand for electric vehicles (EVs) and grid energy storage requires batteries with both high energy density and high safety. Despite the impressive success of lithium-ion batteries (LIBs), the problem of potential safety risks and energy-density bottleneck still exists due to the usage of organic liquid electrolytes (OLEs).
