Ultra-thin battery
Ultra-thin batteries (card batteries) adopt a 0.088mm ultra-thin aluminum-plastic composite film combined with a rolled ultra-thin core structure, achieving thicknesses as low as 2mm. They feature lightweight, flexibility, and high reliability, delivering stable power in extremely limited spaces. These batteries are especially suitable for smart cards, wearable devices, medical electronics, and ultra-thin portable terminals.
FAQs
What is an Ultra-thin Battery?
An ultra-thin battery is a lithium-ion battery with an extremely small thickness, typically less than 2 mm. It can be flexibly embedded into various electronic products to achieve a slim and lightweight design.
What are the typical applications of ultra-thin batteries?
They are mainly used in smart cards, wristbands, smartwatches, medical sensors, portable electronic devices, and ultra-thin wearable devices.
How does the energy density of ultra-thin batteries compare to regular batteries?
Although the thickness is limited, ultra-thin batteries can still maintain relatively high energy density through optimized electrode materials and electrolyte formulations, meeting the endurance requirements of slim devices.
Can ultra-thin batteries withstand bending or slight deformation?
Some flexible ultra-thin batteries are designed to allow slight bending, but conventional rigid ultra-thin card batteries are not recommended to bend to avoid internal short circuits. For curved or bendable battery needs, Irayenergy also offers specially customized bendable curved batteries.
Can ultra-thin batteries be customized in size and shape?
Yes. Irayenergy can customize ultra-thin batteries in various sizes, shapes, and even with flexible circuits according to customer product design requirements.
