From prototype to full scale manufacture

Lithium-ion batteries (LIB) are widey used as a key rechargeable power sources for portable electronic devices.

When compared to other battery chemistries LIBs feature high energy densities, no memory effect, and a relatively low self-discharge when not in use. These advantages explain their rapid spread in the marketplace since their commercial introduction in the early 90’s. Other growing applications for LIBs are from electric vehicles and stationary energy storage devices where they are used to offset times of peak energy demand.

Overall, the market for lithium-ion batteries is developing extremely fast and currently expected to reach a 30-billion-dollar peak in volume by 2025. The main components of the LIB are anode, cathode, separator, and electrolyte. Very often the cathode material is a lithium transition metal oxide (e.g. LiMn2 O4, or LiNix Coy Mnz O2) which is the source of lithium ions. For the anode, graphite is often used as an active material.

During charging, the cathode is delithiated (lithium ions move from the cathode through the separator to the anode), where they are intercalated into the carbon layers of the graphite. Each ion stores a certain amount of energy which is retrieved during battery operation (discharge).

The Lifetime and performance of the LIB are mainly determined by the constituent active materials and the microstructure of the active mass coating and to maintain battery life it is important measure and understand critical parameters such as particle size, shape and distribution, the presence of voids and defects within the particles, porosity, pore tortuosity, and coating thicknesses.

Mantec Technical Ceramics is involved in the manufacture of prototype battery cells and pleased to support the industry sector through the development and integration of modern day battery technology from inception to full scale.
