Concern Parameters: The 10 parameters that a Lithium-ion battery pack’s development covers are high specific energy, specific power, affordable cost, longer life, better safety, wide temperature operating range, non-toxic, fast charging, lower self-discharge and longer shelf life. In the early stages, the cost of a Li-ion battery was $3000 per kWh, while Lead-acid battery cost $150 per kWh.
But over the years, due to multiple benefits of Li-ion battery pack, being 150Wh/kg more than the NiMH, the cost is dramatically falling costing now $150 to $240 per kWh. Tesla’s goal is to reach $100 per kWh on lithium-ion battery packs for the cars.
