Sodium-ion batteries are a promising class of secondary power sources that can replace some the lithium-ion, lead–acid, and other types in large-scale applications. One critical parameters for their potential use is high efficiency wide temperature range, particularly below 0 °C. This article analyzes phase equilibria electrochemical properties sodium-ion battery electrolytes based on NaPF6 sol...

This paper is devoted to the non-symmetric channels. Here we will present t-EC-AUED codes. Böinck and van Tilborg gave a bound on the length of binary t-EC-AUED codes. A generalization of this bound to arbitrary alphabet size is given. This generalized Böinck van Tilborg bound, combined with constructions, is used to determine the length of some optimal binary and ternary t-EC-AUED codes. The s...
