![]() Its advantages include high capacity, high stability, nontoxicity, and low cost. Indeed, olivine-type LFP has been recognized as one of the most promising cathode materials for rechargeable Li batteries. Most of the work presented in this thesis corresponds to our contribution to this project, consisting of the optimization of low-cost and ecofriendly methods for the preparation of LiFePO4 (LFP) and the development of nanostructured and hybrid composites based on this cathode material and conductive polymers or conductive nanocarbons like graphene. The European Project SOlid MAterials for high power Li polymer BATteries (SOMABAT) aimed to develop more environmentally friendly, safer and better performing Li batteries. Yet, this implies new requirements such as a combination of high energy and power densities, longer cycling life and, last but not least, substantially reduced costs. ![]() Lithium ion batteries are the power sources of choice for portable electronics, power tools and electric base transportation and they are ready to take over other niche and mainstream applications (from wearables to smart grid support to electric vehicles).
