Özet

With the growing popularity of electric vehicles (EV), the demand for battery minerals and research activities on battery technologies are continuously increasing. Conventional batteries like lead-acid and Ni-Cd batteries are being replaced by high energy density batteries including Li-ion ones. ‘Li-ion batteries’ is a vague term used for different combinations of materials containing lithium in different proportions to manufacture batteries. Lithium-ion batteries come in a variety of different combinations with the negative electrode usually made from carbon or lithium titanate (Li₄Ti₅O₁₂) while the positive electrode can be lithium cobalt oxide (LiCoO₂), lithium nickel oxide (LiNiO₂), lithium manganese oxide (LiMn₂O₄), lithium iron phosphate (LiFePO₄), lithium nickel cobalt aluminum oxide (Li(Ni_xCo_yAl_1-x-y)O₂), etc. There are some very promising high performing novel materials like Li metal, Li(Si), graphene, and graphene vanadium ribbons which are in their development stage. This study, through a literature survey, provides a review of various types of electrodes used in the development of lithium-ion batteries as well as a brief description of some of the novel materials under development. Factors that affect the performance of Li-ion batteries and current technological limitations are discussed. Finally, the challenges and expectations of such batteries are summarized.
