Driven by electric vehicles (to combat city pollution), energy storage (combined with renewable energy to reduce greenhouse gases) and portable communication devices, the Li ion battery market is growing at 12% Compound Annual Growth Rate (CAGR) and will be >1200 Gigawatt-hours at a value of more than 75 Billion USD by 2025. Most automotive companies are now investing in batteries and are in a race to patent critical next generation battery technologies and battery management systems.
To put it in a tangible perspective, one Gigawatt-hour of battery energy is enough to make 10 million Tesla Model S cars. However, battery technology is still evolving. The latest Tesla Model S electric car is claimed to have a range of 402 miles with single charge, and 15 minutes charging time for a charge of 136 miles. Future battery technologies like solid-state or lithium-sulphur batteries will likely push this range to well over 1000 miles and much faster charging time.

Controlling battery thermal characteristics: Separator, electrode and electrode coating
Like the human body, the operating temperature of a battery should always be monitored, protected and kept at an optimal level. Proper battery thermal management ensures longer lifespan by keeping the cells within a limited temperature range during storage, operation and charging. Understanding how much heat can be dissipated by the cells requires understanding of the basic heat transfer properties of the cell design. To investigate these thermophysical properties, NETZSCH offers Laser/Light Flash Analysis systems (LFA) as well as Differential Scanning Calorimeters (DSC).
Each time a material is exposed to temperature changes – it shows a variation in its dimension. To predict the deformation and stresses in the separator in battery cells, it is necessary to measure the expansion/shrinkage behavior. Thermomechanical Analysis (TMA), expressed by the coefficient of thermal expansion (CTE), achieves this.
Processing parameters: How to apply battery slurry onto the electrode
Blade coating or slot die coating typically processes a battery slurry. During these processes, the slurry is undergoing mid-level shear rates for a short period, followed by gravitational stresses acting on the slurry after the coating process. This has impact on the leveling behavior at low shear rates and film uniformity. Rheology provides access to these flow properties of battery slurries.
