Mineralogical Characterization of Baptistina Asteroid Family: Implications for K/T Impactor Source

, 2011
Bottke et al. (2007) linked the catastrophic formation of Baptistina Asteroid Family (BAF) to the K/T impact event. This linkage was based on dynamical and compositional evidence, which suggested the impactor had a composition similar to CM2 carbonaceous

Amorphous Lithium Borate Coating Enhances the Electrochemical Performance of Lithium Manganese Iron Phosphate Cathodes for Highly Stable Lithium‐Ion Batteries

Batteries &Supercaps, EarlyView.
A novel amorphous Li2B4O7 coating significantly enhances the electrochemical performance and cycling stability of LiMn0.6Fe0.4PO4 cathodes for lithium‐ion batteries. The coating improves lithium‐ion conductivity, suppresses manganese dissolution, and enhances rate capability. Herein, a scalable strategy for stabilizing high‐voltage cathode materials is

Ag‐Embedded Carbon Nanotube Bucky Papers for Lithium Metal Full Batteries

Batteries &Supercaps, EarlyView.
The lithiophilic 3D carbon host is fabricated with multi‐walled carbon nanotubes and silver nitrate as an Ag precursor for the Li metal anode, which provides a conductive pathway and site for high Li affinity. Owing to lowered Li nucleation overpotential and uniform Li deposition, the Li@Ag/MCBP–10 with variable cathode exhibits enhanced cycle ...

Microwave‐Assisted Surfactant‐Engineering Approach for Rapid Synthesis of Lithium–Manganese‐Rich Oxide Cathode for Lithium Metal Batteries

Batteries &Supercaps, EarlyView.
A rapid coprecipitation process combining microwave irradiation and surfactant is used to synthesize high‐capacity lithium–manganese‐rich oxide cathode for lithium batteries. Surfactant micelles provide morphology control and microwave boosts the reaction time.
