Fast charging of Li-ion Battery (LIB) in EVs would reduce refueling time and accelerate the transition to electric transportation. However, charging at high rates can degrade LIB performance affecting its range, life, and safety characteristics. For e.g., LIB using graphite anode is not safe upon fast charging causing thermal runaway. Currently, industries provide fast chargeable battery technology using Li4Ti5O12 coupled with LiNiMnCoO2 assuring safety. However, Li4Ti5O12 has limited capacity (170mAh/g) and expensive. On the other hand, TiO2 anatase is inexpensive with capacity of 335 mAh/g. In this talk, we present our work on developing fast chargeable, safe and inexpensive LIB technology using mesoporous TiO2 (meso-TiO2) coupled with mesoporous LiMnFePO4. We will present synthesis strategies for the above cathode and anode materials, which exhibit unique morphology of micron-size mesoporous secondary particles comprising interconnected primary nanoparticles showing impressive storage and rate performances with long cycle. |
