CUSTOMCELLS® - HIGH TEMPERATURE TOLERANT RECHARGEABLE LITHIUM-ION TECHNOLOGY

Until now available lithium-ion battery cells are usually limited to a very narrow operation temperature range. Other energy storage systems, such as lithium-metal batteries, may allow higher application temperatures, but at the same time they also have a high risk potential and are not rechargeable. Still other battery systems only tolerate a few degrees higher temperature range, but do not cover the very high temperatures that occur during autoclaving or deep drilling for example.

  • In the oil & gas sector, battery technology is suitable for supplying power to logging and monitoring equipment, for example in combination with a generator.
     
  • In the field of medical devices, the technology is suitable for wireless power supply to devices that are hot sterilized. The battery is autoclavable.
     
  • In the area of industrial plants, this technology is suitable, for example, as an energy back-up system for actuators in safety-critical areas where high temperatures occur in the event of a disaster, but where a lithium metal battery is not required for safety reasons.
     
  • The CUSTOMCELLS® high temperature technology is also suitable for the monitoring and control of safety-relevant areas or particularly hazardous areas where high ambient temperatures can occur.
     
  • CUSTOMCELLS® offers all services from feasibility studies to testing. We have high internal analysis and test capacities and about 18 years of experience in the development and production of Li-ion cells. Development is carried out in-house and together with strong partners.

     

LITHIUM-ION CELL TECHNOLOGY FOR ELEVATED TEMPERATURE USAGE

Illustration notes:

  • Conventional lithium-ion battery cells only guarantee a high life expectancy in a very limited temperature range (typically 0-40°C). When operated or stored at temperatures above 60°C, they age particularly quickly, which is reflected in a prompt reduction in storage capacity.
     
  • The development of CUSTOMCELLS® lithium-ion high-temperature technology enables a particularly long operating life at elevated temperatures. The comparison with a previously available lithium-ion battery for higher temperatures shows the technological lead of the development.
     
  • CUSTOMCELLS® high-temperature technology, for example, ensures a significantly longer battery cell life at 75 °C until a remaining capacity of 80% is reached.
     
  • In addition, the cell technology is able to remain available as a rechargeable battery cell for a longer period of time even at exceptionally high temperatures.

HIGH TEMPERATURE LITHIUM-ION BATTERIES - ZIM-Example of Success

New Li-ion batteries meet the highest safety standards at temperatures up to 150 °C. Even under extreme application conditions, such as in deep geological drilling, they reliably supply energy for sensors and can be charged on site. The batteries are available for a variety of other applications. Conventional lithium-ion battery cells only guarantee safe use and an acceptable life expectancy within a limited temperature range (typically 0 °C to 40 °C, maximum 60 °C). Other energy storage systems such as lithium metal batteries allow higher application temperatures, such as those found in deep drilling, but at the same time have a high risk potential and are not rechargeable. When operating so-called MWD (Measurement While Drilling) devices, in which the measuring equipment is integrated into the drill string behind the drill rig, the sensors used must be supplied with energy. This is done by a generator in the drill head, which is driven by the drilling fluid, but does not provide the same power throughout. Therefore, batteries that can withstand the extreme conditions are needed as an energy buffer.

The product and its innovation

Stimulated by the need for MWD equipment to measure boreholes, Custom Cells Itzehoe GmbH, the Fraunhofer Institute for Silicon Technology (ISIT) and the Canadian company Evolution Engineering Inc. have set themselves the goal of developing lithium-ion batteries that are particularly safe and can be discharged and charged at high temperatures. This would eliminate the need to change the batteries that were previously necessary for drilling. In the ZIM cooperation project, ISIT has developed a concept for magnetic field-reduced cells in Li-Ion technology, while Custom Cells Itzehoe concentrated on the development of high-temperature resistant battery cells based on a novel Li-Ion cell chemistry with new material combinations. The Canadian partner Evolution Engineering Inc. was responsible for assembling the cells into battery packs, adapting the battery management system and conducting field tests.

The market and customers

As a result of the development and production of the first sample series, CUSTOMCELLS® offers customer-specific configurable Li-ion battery cells that can be reliably charged and discharged in the temperature range from 0 °C to 150 °C, offer a high degree of safety against thermal penetration and metal fire and can be used with a long service life even under harsh environmental conditions. The market potential for high-temperature lithium-ion batteries is large. In addition to the already existing use in borehole measurements, there are many other possible applications. They are suitable as energy suppliers, for example, for the wireless energy supply of medical technology devices that are hot sterilised, for monitoring safety-relevant or particularly hazardous areas where high ambient temperatures can occur, or as energy back-up systems for actuators in safety-critical areas where high temperatures occur in the event of a disaster.
