CATL introduces sodium-ion battery

Yesterday, the Chinese battery manufacturer CATL revealed a sodium-ion battery and a system that makes this new type of battery compatible with conventional lithium-ion batteries. This could compensate for the lower energy density of sodium-ion batteries without having to sacrifice their advantages. The manufacturing costs for sodium-ion batteries and cells are said to be cheaper, with one of the reasons being that resource prices for conventional battery raw materials such as lithium, cobalt and nickel have risen sharply in recent months.
