Development of practical lithium (Li) metal batteries (LMBs) remains challenging despite promises Li anodes (LMAs), owing to dendrite formation and highly reactive surface nature. Polyolefin separators used in LMBs may undergo severe mechanical chemical deterioration when contacting with LMAs. To identify the best polyolefin separator for LMBs, this study investigated separator-deterministic cy...

In this paper, finite-time stability and practical stability problems for a class of linear continuous time-delay systems are studied. Based on the Lyapunov-like functions, that do not have to be positive definite in the whole state space and not need to have negative definite derivatives along the system trajectories, the new sufficient finite-time stability conditions are obtained. To obtain ...

The packing layout for loading boxes of identical format on a pallet can be determined algorithmically. This is important when performing automated packing by a robot. The well-known four-block heuristics and G4heuristics produce very efficient loading patters in most practical cases. In addition to the number of boxes on the pallet, one has to maximize the stability of the loading. This paper ...
