Batteries are disclosed. In some embodiments, a battery includes a cathode having a composition that includes a manganese oxide. The composition has an X-ray diffraction pattern with a first peak at about 18 degrees, a second peak at about 22 degrees, and a third peak at about 32 degrees.

Battery cathodes

A method of making a cathode for a lithium primary battery includes lithiated manganese dioxide and a carbon fluoride. The cathode can provide high capacity and voltage with low gassing.

Method of making cathode

Batteries and methods of making batteries are disclosed. In some embodiments, a method of making a battery can include contacting a manganese oxide with lithium hydroxide and lithium bromide and/or lithium chloride, and incorporating the manganese oxide into a cathode of the battery.

A method of making a lithium electrochemical cell includes treating the cathode active material with an agent that includes lithium but not sodium. A cathode including the cathode active material, an anode, a separator, and an electrolyte are assembled in a housing to provide a cell containing less than 1500 ppm by weight of sodium.

Method of making non-aqueous electrochemical cell

A battery having an anode including an alkali metal as the active material, a cathode having, for example, iron disulfide as the active material, and an electrolyte including an organic solvent and an aluminum salt selected from the group consisting of aluminum iodide and aluminum tri(sec-butoxide).

Battery with electrolyte containing aluminum salt

A lithium electrochemical cell includes an electrolyte having a mixture of solvents including propylene carbonate (PC) and dimethoxyethane (DME), and a salt mixture. The salt mixture includes lithium trifluoromethanesulfonate (LiTFS), and lithium trifluoromethanesulfonimide (LiTFSI), and the cell contains less than 1500 ppm by weight of sodium. The mixture of solvents can further include ethylene carbonate (EC).

A primary electrochemical cell includes a cathode including lambda-manganese dioxide (&#x3bb;-MnO), an anode including lithium or a lithium alloy, a separator interposed between the cathode and the anode, and a non-aqueous electrolyte contacting the anode and the cathode.

Primary lithium electrochemical cell

Particulate MnO, having simultaneously a micropore surface area greater than 8.0 m/g, desirably between about 8.0 and 13 m/g and BET surface area of between about 20 and 31 m/g within the context of an MnOhaving a total intraparticle porosity of between about 0.035 cm/g and 0.06 cm/g produces enhanced performance when employed as cathode active material in an electrochemical cell, particularly an alkaline cell. The average pore radius of the meso and macro pores within the MnO(meso-macro pore radius) is desirably greater than 32 Angstrom.

Manganese dioxide for alkaline cells

An alkaline battery includes a cathode including lambda-manganese dioxide, an anode including zinc, a separator between the cathode and the anode, and an alkaline electrolyte contacting the anode and the cathode.

Alkaline battery

A primary electrochemical cell includes a cathode including lambda-manganese dioxide (&ggr;-MnO ), an anode including lithium or a lithium alloy, a separator interposed between the cathode and the anode, and a non-aqueous electrolyte contacting the anode and the cathode.

A battery, a primary alkaline battery, has a cathode including manganese dioxide, carbon, and a binder. The manganese dioxide is selected to have a high power coefficient to provide the battery capable of high current discharge.
