The lithium cobaltate and the manganate spinel are in a weight ratio of lithium cobaltate: manganate spinel between about 0.9:0.1 to about 0.6:0.4.
Also disclosed are a method for producing such a spinel lithium manganate, and a nonaqueous electrolyte battery having a positive electrode containing the spinel lithium manganate.
The lithium manganate is cubic particles and the particles have pores therein.
Corrosion-inhibiting pigments based on manganese are described that contain a heptavalent (permanganate) or hexavalent (manganate) compound.
Many permanganate or manganate compounds are presented that can equal the performance of conventional hexavalent chromium systems.
A lithium manganate having high output power and excellent high-temperature stability.
By this method, lithium manganate having large grain sizes and high characteristics can be produced on an industrial scale.
Disclosed is a positive electrode active material including a plurality of crystal particles comprising lithium manganate with a spinel structure.
The lithium manganate is a compound having a spinel structure represented by the formula (1) below or a compound obtained by partially substituting a site in the compound where Mn or O exists with an other element.
Therefore lithium cell comprising such an active material of lithium manganate has a high initial discharge capacity of over 95 mAh/g and an excellent cycle characteristic.
