Cobalt-free lithium-manganese-nickel-oxide electrode materials for lithium cells and batteries, notably rechargeable Li-ion batteries, are described herein. These electrode materials have a lithiated-spinel structure with the general formula LiMnxNiyMzO2, or alternatively in lithiated-spinel notation, Li...
Lithium-ion batteries make use of cobalt for stability. The use of cobalt, nonetheless, has its drawbacks. The drawbacks have to do with cost, and with availability, and the two as usual are intertwined. "Cobalt is a vital ingredient in currentlithium-ion batteries, but cost, a limited sup...
MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries). In a new study, t...
The doping process, Xin explained, eliminates the need for cobalt in commercial components critical for lithium-ion battery functioning and replaces it with nickel. "Doping also increases the efficiency of nickel," said Xin, which means EV batteries now require less nickel to work—something that ...

In Li-ion batteries, particularly those using lithium cobalt oxide or nickel...
The development of lithium-ion batteries for use in applications such as electric vehicles has been continuing with much of the attention focused on finding a substitute for the graphite electrode used as the anode. But attention also is being paid to the cathode because of the challenge of ...
