One of the most difficult challenges is to produce affordable batteries offering long driving range. Currently, the lithium ion (Li-ion) batteries have become the feasible solutions to EVs or PHEVs for energy storage. The emerging industry of Li-ion battery is, however, being besieged by five antagonists, i.e., the high initial cost, the large residual available capacity after retiring from EV or PHEV, a great amount of useful and treasure materials in waste batteries, the latent hazards with careless assembly and storage, and the serious impacts on environmental sustainability without appropriately processing exhausted batteries. In this study, a new ecosystem conception and a novel business model for Li-ion batteries in their total life-span applications are purposed to eliminating above-mentioned antagonists. This ecosystem consists of four stages, including the materials and components for batteries, the first use in EVs or PHEVs, the second-use (or second-life and repurposing) in other applications, and the recycling of treasure materials inside batteries. Further, this business model concentrates on the last two stages for the reimbursing profits to compensate the investment and consumption in the first two stages. Taking an electric bus (e-Bus) for example, its Li-ion battery system, normally defined as the most expensive consumer part in vehicle, can earn extra profits by being repurposed to a renewable energy generation system (REGS). Finally, the treasure metallic and rare earth materials in battery cells can be retrieved and reused in many profitable applications. The estimated remuneration percentage probably reaches to 46.88% over 15-year service life of a Li-ion battery system. " |
