Lithium Polymer Battery Series
Custom Shaped Lithium Polymer Battery Cells
ASOL supplies custom shaped lithium polymer battery cells for compact products where a conventional rectangular pouch cell does not fit the available space.
Existing shapes and OEM/ODM solutions can be matched to device geometry, electrical requirements and connection layout, subject to specification confirmation.
Product Overview
The available range includes teardrop, semi-circular, angled curved, ultra-thin, U-shaped, T-shaped and ring-shaped lithium polymer battery formats, together with other custom battery geometries. Battery selection starts with the usable enclosure space, required runtime and load profile, charging design, and the position of tabs, wires or connectors.
Key Features
Shape Options for Restricted Spaces
Non-rectangular outlines help use available space around housings, circuit boards and other internal components.
Compact and Ultra-Thin Formats
Different thickness and footprint options support compact products with tightly controlled internal packaging.
Configurable Connections
Tab direction, polarity, lead exit, wires and compatible connectors can be specified for the intended assembly layout.
Project-Specific Selection
Existing models and feasible custom solutions are selected against the device drawing and confirmed electrical requirements.
Available Battery Shapes
These images represent shape families and do not identify exact dimensions, capacities or individual cell specifications. Additional geometries may be available for suitable OEM/ODM projects.
Teardrop
A tapered outline for products with a wider body and a narrowing internal cavity, including compact wearable and handheld layouts.
Semi-Circular
A half-round format suited to curved enclosures or layouts that need to preserve space around a circular component.
Angled Curved
An angled arc profile for assemblies that follow a curved housing while routing around adjacent electronics.
Ultra-Thin
A low-profile pouch format for slim wearable electronics, compact smart devices and other thickness-limited products.
U-Shaped
A U-profile may accommodate a central component or opening where the surrounding envelope can hold the battery.
T-Shaped
A T-profile can use connected areas of unequal width within an irregular enclosure.
Ring-Shaped
Curved ring-cell formats support wearable electronics designed around a circular or partial-ring enclosure.
Other Custom Geometries
Other outlines can be discussed from a device drawing, available space and complete electrical requirements.
OEM / ODM Customization
ASOL offers existing custom-shaped cell options and project-specific OEM/ODM support. Final specifications are confirmed against technical feasibility and the intended device design.
Shape and Mechanical Envelope
Outline, curvature, maximum dimensions and thickness are defined from the available space and device drawing.
Capacity and Electrical Requirements
Capacity targets, normal and peak current, runtime and charging requirements are considered together for cell selection.
Tabs, Wires and Connectors
Polarity, tab direction, lead exit, wire length and compatible connector requirements can be specified for assembly.
Protection and Temperature Sensing
Protection circuits and temperature-sensing arrangements can be included where appropriate for the selected configuration and application.
Applications
Wearable Electronics
Compact wearable products that need battery geometry aligned with a curved or irregular enclosure.
Compact Smart Devices
Connected electronics with limited internal space shared by the battery, PCB, sensors and charging components.
Portable Electronic Equipment
Portable products where a shaped or ultra-thin pouch cell can improve use of the available battery compartment.
Space-Constrained OEM Devices
OEM products requiring a cell outline, connection arrangement and electrical specification matched to the device design.
Frequently Asked Questions
What shapes of lithium polymer battery cells are available?
Available formats include teardrop, semi-circular, angled curved, ultra-thin, U-shaped, T-shaped and ring-shaped cells. Other geometries may be available depending on the device requirements and technical feasibility.
Can ASOL customize the battery shape and dimensions?
Yes. ASOL supports OEM/ODM requirements for cell outline, curvature, dimensions and thickness when technically feasible. Final requirements are confirmed from the device drawing and complete electrical specification.
What information is required for a custom shaped battery project?
Please provide the application, device drawing or available battery space, voltage and capacity or runtime target, normal and peak current, charging method, tab or connection requirements, and estimated quantity.
Can tabs, wires and connectors be customized?
Polarity, tab direction, lead exit, wire length and compatible connectors can be specified for the intended assembly. The approved drawing defines the final connection arrangement.
Can protection circuits be supplied with custom shaped cells?
Protection circuits and temperature sensing can be supplied where appropriate for the selected cell and application. Requirements must be confirmed before the final configuration is approved.
How can I request samples or a quotation?
