Features of freeze-drying synthesis and electrochemical properties of cathode materials based on Li2CuO2

Cathodic materials based on Li₂CuO₂ are synthesized by cryochemical technique. The Li₂CuO₂ anomalous electrochemical behavior during lithium intercalation-deintercalation is shown to be fundamental feature. Such behavior is not connected with chemical mhomogenitv Low synthesis rate of Li₂CuO₂ at temperatures lower than 700°C can be explained by nearness of the low-temperature border of thermodynamic stability range.
