Abstract High‐temperature calorimetry (HTC) originated in the 20th century as a niche method to enable measurements not easily accomplished with acid solution calorimetry, combustion vapor pressure, or EMF methods. Over time, HTC has evolved into versatile approach accurately quantify formation, phase transition, surface and interfacial enthalpies of wide range materials including minerals refractory inorganic compounds. This evolution been result numerous adjustments experimental setups...
Li-excess Mn-based disordered rock salt oxides (DRX) are promising Li-ion cathode materials owing to their cost-effectiveness and high theoretical capacities. It has recently been shown that Mn-rich DRX Li1+xMnyM1–x–yO2 (y ≥ 0.5, M hypervalent ions such as Ti4+ Nb5+) exhibit a gradual capacity increase during the first few charge–discharge cycles, which coincides with emergence of spinel-like domains within long-range structure coined "δ phase". Here, we systematically study structural...
ABSTRACT A series of tetrapolyesters were obtained by polymerizing phloretic acid, hydroquinone, p ‐hydroxybenzoic or its derivatives, that is, vanillic acid syringic and dodecanedioic acid. Each monomer was polymerized in acetylated form, except for the diacid to undergo polymerization acidolysis. Initial polymerizations had shown use resulted better polymer properties than with ‐coumaric The predominantly renewable polymers melt using a two‐stage condensation process whereby antimony(III)...
Manganese-based disordered rock salt (DRX) oxides are promising new generation lithium-ion cathode materials due to the low costs and high theoretical capacities. Recent research has revealed that DRX compounds with manganese content, denoted as Li 1+x Mn y M 1-x-y O 2 (where y>0.5 represents hypervalent d0 ions such Ti 4+ Nb 5+ ), undergo a gradual capacity increase over initial charge-discharge cycles. This phenomenon coincides development of localized domains exhibiting spinel-like...
A path toward more sustainable battery cathodes is using Li x Na 1-x CoO 2 layered oxides, which reduces the needed by traditional cathodes. During cycling, around 28 % of within structure LiCoO goes unused and a portion it could be replaced Na. In this work, we show how sodium substitution serves not only to reduce produce these cathodes, but also stabilize materials making enthalpy formation exothermic. An enthalpic minimum has been found at 10 with without major changes oxide structure....
