Preparation and characterization of graphite anodes for lithium ion batteries
Humana, Rita; Ortiz, Mariela; Thomas, Jorge; Real, Silvia; Sedlarikova, Marie; Vondrak, Jiri; Visintin, Arnaldo (The Electrochemical Society, 2014)The lithium-ion batteries are energy storage systems of high performance and low cost. They are employed in multiple portable devices and these require the use of increasingly smaller and lighter batteries with high energy ... -
Preparation and characterization of positive electrode of NiMH batteries with cobalt additives
Ortiz, Mariela; Real, Silvia; Castro, Élida Beatriz (Elsevier, 2014-02-18)The present paper shows the preparation and characterization of alkaline batteries cathodes formed by nickel hydroxide with the addition of cobalt. This additive was incorporated by two methods: on the electrode surface, ... -

Study of the electrochemical behavior of different carbon materials as anode material for lithium ion batteries
Ortiz, Mariela; Visintin, Arnaldo; Real, Silvia (Topical Meeting of the International Society of Electrochemistry, 2017-03-19)Since the lithium ion battery was first commercialized by the Sony Corporation in 1991, the development for improvement it is critical for advancements in a variety of applications ranging from hybrid electric vehicles to ... -
Synthesis and electrochemical properties of Nickel oxide as anode for Lithium ion batteries
Ortiz, Mariela; Visintin, Arnaldo; Real, Silvia (Topical Meeting of the International Society of Electrochemistry, 2017-03-19)Transition-metal oxides (MO, where M is Fe, Ni, Co and Cu) have been studied since these materials were proposed by Tarascon and co-workers [1-6]. These oxides can offer higher capacities (600-1000 mAh g-1) that graphite ...
