High Power Cells
Fast Li+-ion transport through the liquid phase, but also through the interphases is essential for current and future high-power applications with e.g. fast charging capability. Therefore, the Li+-ion transport properties within the electrolyte must be adapted by a smart choice of the right electrolyte solvent mixtures, Li+-ions salt mixtures and/or additive combinations in order to meet these requirements while ensuring a long battery life of the battery.
High Energy Applications
With the application of advanced electrode materials, such as silicon at the anode side, unconventional electrolyte solutions are mandatory in order to enable these technologies. Only with the utilization of electrolytes adapted by new choices of electrolyte solvents and/or additives, advanced lithium-ion cells with increased energy density will be able to keep up with conventional graphite-based cells in terms of cycle life.
High Voltage
Current state-of-the-art electrolytes lack electrochemical stability towards high voltage electrode materials, which is especially of interest in the development of cobalt-free cathode active materials and/or increasing the operating voltage of state-of-the-art cathode active materials such as
NMC. By skillful adaption of either electrolyte solvent mixtures, Li-salt blends and/or additive combinations the compatibility of electrolytes within lithium-ion batteries using increased cut-off voltages can be achieved.
High Safety
Some applications require increased intrinsic safety properties. Examples are medical and large-scale stationary energy storage systems or maritime and mining applications. The electrolyte plays a crucial role in order to meet the requirements. The safety properties of lithium-ion cells can be optimized by the appropriate choice of solvent and co-solvent mixtures, lithium salt or mixtures and safety additives such as flame retardants or shutdown additives. Ideally, battery life and performance is not affected.
High and Deep Temperature Application
The application range of lithium-ion cells is currently very much limited in the temperature range due to the use of standard electrolyte mixtures. Normally between 0 and +55 °C during charge and –20 and +60 °C during discharge. With the clever selection of either electrolyte solvent mixtures, Li-salt blends and/or additive combinations, the range of temperature can be broadened or moved towards either the low or high temperature range.
