High Temperature Lithium Batteries (HT-LiB): From Fundamental Science to Vehicle Integration
The high power energy storage demanded for the most efficient hybridisation of heavy vehicles has been the subject of a preliminary study based on the vehicle implementation issues, the energy storage unit itself, as well as fundamental limitations of battery materials. From this a radical novel technology; a lithium battery working at ca 80-110°C (HT-LiB), is stated to have promise of: i) a much reduced vehicle cooling system, ii) a faster charge/discharge of the energy storage, iii) higher C-rates in the cells – allowing the requested power, and iv) new classes of materials to be implemented creating both cost savings and market/IP opportunities. Foreseen problems are primarily cold-start issues and unknown (predictability of) life-length for the battery cells. All of the issues above are in this R&D proposal tackled in four sub-projects outlined below and including academic/industry direct research as well as in-kind contributions. This proposal is a direct outcome of a pre-study made 2012-13 within the Swedish Hybrid Vehicle Centre.
