Surface modifications of electrode materials for lithium-ion batteries: status and trends

Interface modification in high voltage spinel lithium-ion battery by using N-methylpyrrole as an electrolyte additive

“…Conducting polymer coating is also reported as another strategy, which not only be able to protect the surface of cathode, but also to serve as a conductive matrix. Compounds such as aniline [17,18], pyrrole [19,20], 3,4-ethylenedioxythiophene [21,22], acrylonitrile [23] [24]. Employing monomer units of conducting polymers as electrolyte additives is a more economic and effective way to in-situ coat the electrode [25][26][27].…”

Critical review on lithium-ion batteries: are they safe? Sustainable?

“…In addition, at x> 0.5, the compound is structurally unstable when heated above 200 °C and evolves oxygen and decomposition products. Doping at the cobalt site can reduce these problems [12], in particular Al doping [13], which [20] for a review), and more recently poly(tris(2-(acryloyloxy)ethyl)phosphate) [21] without solving entirely the problem. In this last case, the authors were also too optimistic when claiming that it suppressed the exothermic reaction: it only shifted the exothermic peak temperature from294 to 284 °C, and reduced the peak from 649 to 576 J g −1 .…”

Effects of High Energy Milling on the Carboncoated Lithium Iron Phosphate Precursor Nature

“…Olivine lithium iron phosphate (LiFePO 4 , LFP) is used in lithium-ion batteries as cathode material [1,2] . LFP holds the desirable merits of abundant raw materials, non-toxicity, high thermal stability, suitable voltage of 3.4 V (vs Li + /Li) and theoretical capacity of 170 mA·h/g [3,4] .…”

“…LFP holds the desirable merits of abundant raw materials, non-toxicity, high thermal stability, suitable voltage of 3.4 V (vs Li + /Li) and theoretical capacity of 170 mA·h/g [3,4] . It meets both demands of high energy density and environmental friendliness and is an adequate cathode for power battery and stationary storage of electrical energy generated by renewable power [5,6,7] .…”
