There are number of challanges to be overcome relating to cell chemistry. Future battery developement requires:
- INEXPENSIVE BATTERIES. Cheaper cells are needed; this can be achieved with the use of new materials as well as the establishment of standardisation
- MORE DURABLE BATTERIES. The cycle life of batteries need to be extended, to thousands of cycles for EV batteries and tens of thousands of micro cycles for HEV. Equally, the calender life of battery will idealy need to be equal to life of vehicle.
- ENERGY AND POWER DENSITY. Both need to be increased, this can be achieved both by the use of new electrode materials and new technologies
- IMPROVED SAFETY. Safety is always one of the most important concerns about Li-ion batteries. Short circuits, thermal runaway and other safety issues need to be prvented.
- MATERIAL AVAILABILITY. Concerns are sometimes raised about the availability of the materials necessary for the construction of large format automative batteries. However, the current estimates of worldwide Lithium reserves total about 13.5Million tons, concluding world has enough reserve for 365 years of current global production of about 37000tons per year.
At Exegi batteries, our in house R&D team in collaboration with some government accreciated testing labs is in continous endevour to overcome these challenges.
