Surface Modification of Ni-Rich LiNiCoMnO Cathode Material by Tungsten Oxide Coating for Improved Electrochemical Performance in Lithium-Ion Batteries.

Ni-rich NCM-based positive electrode materials exhibit appealing properties in terms of high energy density and low cost. However, these materials suffer from different degradation effects, especially at their particle surface. Therefore, in this work, tungsten oxide is evaluated as a protective inorganic coating layer on LiNiCoMnO (NCM-811) positive electrode materials for lithium-ion battery (LIB) cells and investigated regarding rate capability and cycling stability under different operation conditions.

Lyme Disease Manifestations in the Foot and Ankle: A Retrospective Case Series.

Lyme disease is the result of Borrelia burgdorferi bacterial infection after exposure from a tick bite. A pathognomonic finding in early-stage Lyme disease is an expanding, red macular ring known as erythema migrans. Lyme arthritis is a late-stage manifestation of this disease, affecting the large, weightbearing joints with intermittent pain and swelling.
