Density measurement of lithium-containing electrolytes

The density of liquid lithium-ion containing electrolytes dissolved in organic solvents can be monitored during the production and in the final product. Density measurement represents a fast, reliable and efficient quality control for electrolyte producers, but also for accumulator manufactures.

Lithium-containing electrolytes and the automotive market

Lithium-ion accumulators, also frequently referred to as lithium-ion secondary batteries, are to-date among the most frequently used energy sources in electrically powered vehicles. Lithium-ion accumulators offer a high energy density which makes them suitable components in the electric vehicle market.

These rechargeable batteries consist of a stack of several cells, each of them containing two electrodes and an electrolyte containing lithium (Li) ions as charge carriers. The lithium-ion (Li+) carries one positive charge.

Secondary batteries containing Li-ion electrolytes are suitable to match the growing demand of alternatives to combustion engines. These batteries are not only used for cars, but also for all kinds of electronic devices such as mobile phones, tablets, digital cameras or flashlights.

Many factors drive the growth of the secondary battery market. Among them are the increasing acceptance of electrical vehicles to reduce the carbon footprint, and the increasing interest in alternative energy sources. On top of that, the continuous growth of automotive sales generates a high demand for replacement automotive batteries.
