Lithium Ion Batteries: Characteristics, Recycling and Deep‐Sea Mining

Battery Energy, Volume 3, Issue 6, November 2024.
Composite electrodes, as cathode materials, are found to increase electrode stability along with metal carbide‐based anode materials that have shown greater thermal and oxidation resistance. Recycling centres of spent lithium ion batteries are on the rise, with improved techniques such as biometallurgy improving the efficiency of recovering precious ...

Molybdenum isotope fractionations between ferromanganese oxides and seawater influenced ancient sedimentary isotopic signatures

Communications Earth & Environment
The use of molybdenum isotopes (δ98Mo) as a paleo-redox proxy requires quantifications of fluxes and isotopic fractionations in each molybdenum sink.

Spatial variability of Arsenic Concentrations in Baltic Sea surface sediments in relation to Sea Dumped Chemical Munitions

E3S Web of Conferences, 2013
Arsenic concentration in marine areas are higher than in terrestrial environment, because most of its compounds are water soluble, and water bodies serve as a sink for this element.

Competitive Scavenging of Trace Metals by HFO and HMO during Redox-driven Early Diagenesis of Ferromanganese Nodules (11 pp) [PDF]

, 2018
-: Dedicated to Prof. Dr. Ulrich Förstner on his 65th birthday Background: Surface complexation models (SCM) alone have yet less successfully reproduced sorption isotherms of hydrous manganese oxides (HMO).

Zircon effect alone insufficient to generate seawater Nd-Hf isotope relationships [PDF]

, 2011
[1] Many studies have suggested that continental weathering inputs have controlled the dissolved oceanic budget of hafnium (Hf). However, whether the offset of seawater Nd‐Hf isotope compositions from the terrestrial array can be fully generated by ...

Forms and distribution of Ce in a ferromanganese nodule

Marine Chemistry, 2018
Author(s): Marcus, MA; Toner, BM; Takahashi, Y | Abstract: We studied the distribution and speciation of Ce in a previously-characterized ferromanganese nodule from the South Pacific Gyre using X-ray microspectroscopy.We find Ce in three types of environment – diffusely in all parts of the nodule except the Fe-rich, Mn-poor “matrix”, fluorapatite ...
