The strain variation of LiNi0.8Co0.1Mn0.1O2 (NCM) during cycling deteriorates its structural integrity and causes microcracks, resulting in a quick capacity decay. Enhancing NCM's can suppress microcrack occurrence, thereby increasing retention. Here, we experimentally realize the suppression NCM by enhancing stability via synchronous Li2SiO3 coating. Li2SiO3-coated (NCM@LSO) is prepared precoating solid-state lithiation methods. NCM@LSO exhibits good with high retention 97% after 500 cycles...

Most stab-proof vests in use are made from metal plates, whose weight, bulk, and rigidity make them unsuitable for over extended periods of time. Light, thin, flexible clothing that protects against knives other sharp objects is needed. However, achieving high levels puncture resistance comfort remains a challenge. While plain textiles can resist slashing, they cannot withstand stabbing. In this study, we investigated the stab aramid fabrics impregnated with micro-glass particles nano-silica...
