Energy, greenhouse gas, and water life cycle analysis of lithium carbonate and lithium hydroxide monohydrate from brine and ore resources and their use in lithium ion battery cathodes and lithium ion batteries

Battery cathode materials, as well as complete automotive traction batteries, were also included in the LCA's scope beyond Li 2 CO 3 and LiOH 2 O's manufacture to include battery cathode materials as well as complete automotive traction batteries to see the effect that Li lithium production pathways had on these end products. The difference in lithium source, based on battery cathode composition, makes a difference of up to 20% for NMC811 cathode greenhouse gases and up to 45% for NMC622 cathode GHGs. Producing Li 2 CO 3 from brine-based resources reduced life cycle GHG emissions and freshwater use per tonne of Li 2 CO 3 than Ore-based sources. LiOHu00b7H2O produced from brine-based lithium also had less GHG emissions and freshwater consumption per tonne of LiOHu00b7H 2 O than ore-based sources, with less life cycle GHG emissions and freshwater consumption per tonne of LiOHu00b7H 2 O than LiOH2 O from ore-based sources.

The surface triple-coupling on single crystalline cathode for lithium ion batteries

For the first time on SC LiNi 0. 3 O 2 cathode by the hydrolysis of NaPF 6, NaPF 6's triple coupling of concentration-gradient Na+, F-codoping, and surface NaF coating are exploited for the first time. These superior results, according to numerous analysis studies, are mainly due to the SC cathode's excellent structure integrity, the high content of lithium fluoride, and the low solubility of transition metal ions.

A perspective on single-crystal layered oxide cathodes for lithium-ion batteries

As the demand for lithium-ion batteries continues to grow for lithium-ion batteries in the nascent electric-vehicle and grid-storage markets, the need for higher energy density and longer cycle life becomes more apparent. Due to their remarkable cyclability, single-crystal cathode particles with low susceptibility to cracking have recently attracted a lot of attention. This perspective examines the literature on single-crystal cathode synthesis through the lens of classical grain growth theories, gaining insight and possibly accelerating the adoption of the attractive single-crystal cathode morphology.

Cobalt-free, high-nickel layered oxide cathodes for lithium-ion batteries: Progress, challenges, and perspectives

Due to the high energy density, high-nickel layered oxides are enabling rapid development of electric vehicle market growth. However, leading battery manufacturers are still striving to lower manufacturing costs by eliminating the reliance on cobalt in cathode materials. In addition, a perspective on the future research direction on Co-free high-ni layered oxides is given in terms of practical considerations.

Intragranular cracking as a critical barrier for high-voltage usage of layer-structured cathode for lithium-ion batteries

Secondary particles of densely packed primary particles are often used to produce layered cathode cathode, providing high energy density and reduction of cathode side reactions/corrosions, but intergranular cracking are often introduced. We present new findings on the nucleation and expansion of intragranular cracks in the commercial NMC333 layered cathode's thermoplastic foams. As a result, our report found that maintaining structural stability is the first step toward high-voltage operation of layered cathode materials.
