[0012] overview

[0013] This article discusses techniques for shared electrode batteries. In general, different battery configurations are described that include multiple electrodes of one type (eg, cathodes) that share electrodes of another type (eg, shared anodes).

[0014] For example, one or more implementations utilize multiple cathodes and shared anodes. Different cathodes have different properties (such as different chemistry, particle size and distribution, capacity, etc.) designed to provide specific features (such as high energy density, high power density, high cycle life, fast charging, safety, etc.) . Multiple cathode-anode pairings are possible where the battery provides power. For example, if a battery includes two cathodes and a shared anode, one cathode-anode pair is a first cathode and a shared anode, and the other cathode-anode pair is a second cathode and a shared anode. The switching hardware is operable to select one of the plurality of cathode-ano...

Abstract

A shared electrode battery includes multiple electrodes of one type (e.g., two or more cathodes) that share an electrode of another type (e.g., a shared anode). The multiple electrodes of the same type (e.g., the multiple cathodes) can have different characteristics, such as different chemistries, particle sizes and distributions, capacities, and so forth that are designed to provide particular features such as high energy density, high power density, high cycle life, fast charge, safety, and so forth. Multiple cathode-anode pairings of one of the multiple electrodes of the same type with theshared electrode are possible. Switching hardware is operable to select one of the multiple pairings at any given time, allowing the battery to provide power using the cathode having the desired characteristics at that given time. A single battery is thus able to provide these multiple different features.

Description

Background technique [0001] Today, many devices utilize some form of battery for various power needs, such as main power, backup power, etc. Battery life is a major concern, especially in the case of mobile devices such as mobile phones, portable computing devices, wearables, etc. Current battery designs typically provide little flexibility to affect battery performance during various usage scenarios. Contents of the invention [0002] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. [0003] According to one or more aspects, a system includes a battery and switching hardware. The battery includes a shared anode, a first cathode and a second cathode. The switching hardware is o...
