Beyond serving as simple communication tools, mobile devices including smartphones are rapidly evolving into core platforms that support advanced the importance of batteries, as their performance affects the mobile user experience and determines consumer satisfaction.

[Batteries determine mobile device performance and user experience]

Mobile devices such as smartphones, tablets, smartwatches are primarily equipped with pouch type batteries made from lightweight, highly processable film materials. Because the internal space of a mobile device is mostly designed in an irregular shape, pouch cells, which can be manufactured in various forms, are highly versatile. SAMSUNG SDI produces pouch cells through customized designs that meet each customer’s needs.

[Key characteristics required for mobile device batteries]

High capacity is another critical characteristic required for mobile device batteries. Higher capacity increases device usage time and lifespan. Therefore, batteries offering high capacity based on high volumetric energy density(Wh/L) are essential.

Recently, mobile devices have incorporated diverse functions that demand even higher capacity. This is necessary to handle the computations of high-performance processors that consume a lot of power for tasks like gaming, video editing, and AI.

To address this, SAMSUNG SDI is developing a solution to replace the film used in pouch cell casings with stainless steel. Utilizing the stainless steel allows more internal space to be used for electrodes, enabling increased capacity.

In line with technological advancements, mobile devices are expected to become more sophisticated in functionality and continue to diversify with new types of devices. SAMSUNG SDI will remain dedicated to developing batteries that can meet the evolving demands of the market.
