The battery includes an electrolyte activating one or more cathodes and one or more anodes. The electrolyte includes one or more salts in a solvent. The solvent includes one or more organic solvents and one or more silanes and/or one or more siloxanes.

Battery having electrolyte with mixed solvent

The battery includes a cathode and an anode. The anode has a first medium that includes a first active material. The anode also has a second medium including a concentration gradient of a second active material. The battery also includes an electrolytic solution in contact with the cathode and the anode. In some instances, the first medium is positioned so as to protect at least a portion of the second medium from the electrolytic solution. The first medium can also be selected so as to dissipate during discharge of the battery. The first medium can be configured to dissipate enough that one or more of the protected regions of the second medium become exposed to the electrolytic solution during the discharge of the battery.

Primary battery having sloped voltage decay

The battery has an electrolyte that includes an organoborate additive and one or more salts in a solvent. The organoborate additive can be present in a concentration less than 0.2 M or less than 0.05 M. A molar ratio of the organoborate additive:one or more salts is in a range of 4:1 to 400:1. In some instances, the solvent includes one or more organic solvents.

Battery having electrolyte with organoborate additive

The battery has an electrode assembly that includes one or more anodes and one or more cathodes. A first liquid phase is positioned in an active region of the electrode assembly. The first liquid phase includes one or more first flame retardants and an electrolyte. A second liquid phase is outside of the active region and in contact with the first liquid phase. The second liquid phase includes one or more second flame retardants. A third liquid phase is outside of the active region and in contact with the second liquid phase. The third liquid phase includes one or more third flame retardants. The first liquid phase and/or the electrolyte have a density between the second liquid phase and the third liquid phase.

Flame retardant battery

A negative electrode for use in secondary battery with nonaqueous electrolyte having a high voltage and energy density and a superior cycle property, characterized in that the active material comprises composite carbon materials containing massive ball-shaped graphite particles, carbon fibers, and graphite flakes. The massive ball-shaped graphite particles provide porosity to the composite, the carbon fibers improve packing density, conductivity, and stiffness to prevent the body made thereof from swelling and decomposing, and the graphite flakes reduce friction in the mixture. An aqueous, non-fluorine-containing binder is used, along with a titanium negative substrate.
