Patent number: 11714212Abstract: Optical coatings for curved or non-planar substrates are disclosed. Optical coatings may include AR (antireflection) coatings or absorbing (“black” optical) coatings. The optical coatings may include a nanostructure layer formed on top of a stack of one or more materials. Both the nanostructure layer and the stack may be deposited on a curved or non-planar substrate using plasma-enhanced atomic layer deposition (PEALD) to provide conformal coating of the substrate. The nanostructure layer may include a mixture of aluminum hydroxide and aluminum oxide hydroxide that is formed by placing a PEALD-deposited aluminum oxide layer in heated deionized water for a predetermined time period. The materials in the stack may be alternated to provide tuning of the optical properties in the optical coating.Type: GrantFiled: September 10, 2021Date of Patent: August 1, 2023Assignee: Apple Inc.Inventors: Timothy M.

Patent number: 9425441Abstract: Provided are an anode capable of preventing an increase in impedance and variations in characteristics and a battery using the anode. An anode active material layer includes at least one kind selected from the group consisting of simple substances, alloys and compounds of silicon and the like capable of forming an alloy with Li.
