Abstract
The disclosed embodiments relate to a battery cell which includes a set of electrode sheets of different dimensions arranged in a stacked configuration to facilitate efficient use of space inside a portable electronic device. For example, the electrode sheets may be arranged in the stacked configuration to accommodate a shape of the portable electronic device. The stacked configuration may be based on a non-rectangular battery design such as a toroidal design, an L-shaped design, a triangular design, a pie-shaped design, a cone-shaped design, and/or a pyramidal design.

A battery cell, comprising:
- a set of electrode sheets of different dimensions, wherein the electrode sheets are electrically coupled in parallel and arranged in a stacked configuration;
- a pouch enclosing the electrode sheets;
- and
- a rigid plate beneath the stacked configuration of electrode sheets and within the pouch, wherein the rigid plate provides structural support for the stacked configuration of electrode sheets and wherein the set of electrode sheets has a hollow interior portion.
A method for providing a power source for a portable electronic device, comprising:
- arranging a set of electrode sheets of different dimensions in a stacked configuration, wherein the set of electrode sheets has a hollow interior portion;
- disposing a rigid plate beneath the stacked configuration of electrode sheets, wherein the rigid plate provides structural support for the stacked configuration of electrode sheets;
- enclosing the electrode sheets and the rigid plate in a pouch;
- and
- electrically coupling the electrode sheets in a parallel configuration.
A battery pack, comprising:
- a set of electrode sheets of different dimensions electrically coupled in parallel and arranged in a stacked configuration, wherein the set of electrode sheets has a hollow interior portion;
- a rigid plate disposed beneath the stacked configuration of electrode sheets;
- and
- a pouch enclosing the stacked configuration of electrode sheets and the rigid plate.
A portable electronic device, comprising:
- a set of components powered by a battery pack, the battery pack comprising:
- a set of electrode sheets of different dimensions electrically coupled in parallel and arranged in a stacked configuration, wherein the set of electrode sheets has a hollow interior portion configured to receive at least one component of the set of components powered by the battery pack;
- a rigid plate disposed beneath the stacked configuration of electrode sheets;
- and
- a pouch enclosing the stacked configuration of electrode sheets and the rigid plate.
