12 V Lithium ion starter battery with lithium capacitors for improved cold cranking performance
The main scientific objective of the project LiKo was to explore the optimal combination of capacitors and lithium-ion batteries for use as a 12V car starter battery. With increasing partial hybridization of vehicles, the cycle load of the lead-acid battery used to date has increased significantly. Therefore, the researched combination of capacitor and lithium-ion battery is replacing the lead-acid battery technology. The long-term objective is the complete replacement of the lead battery as a starter battery.
The intention was to develop a teaching for technical instructions, by which it is possible to design the battery for an optimum cold start capability as well as for an optimum lifetime. On the basis of the prototypes, the suitability of the technical teaching to be developed was demonstrated and proven.
