Mitacbattery has launched the soft-pack battery cell ST552125, with a lightweight design that breaks the energy density limit

Recently, I Love Audio Network received the Mitacbattery 552125 soft-pack battery cells produced by ShenZhen MItacbattery Techonology Co., LTD.. ShenZhen MItacbattery Techonology Co., LTD., headquartered in Shenzhen, is a leader in the high-end "three-high" lithium battery field - high safety, high energy, and high efficiency. Since its establishment in 2010, the company has been dedicated to the small polymer lithium battery industry and has achieved remarkable success in fields such as smart wearables, 3C digital products, and health care. The soft-pack battery cells have greater flexibility and can better adapt to devices of different shapes and sizes. This makes pouch batteries easier to apply in space-constrained devices, such as smart wearable devices, TWS headphones, tablet computers, etc., because they can be more flexibly shaped into different forms.

Secondly, compared with hard-shell batteries, soft-pack batteries often have a higher energy density within the same size, that is to say, they can store more energy within the same volume. This means that soft-pack batteries can offer greater capacity, extend the battery life of devices, and due to their lightweight design, they can also reduce the total weight of the devices. Below, the author will introduce the appearance and specifications of the Mitacbattery 552125 soft-pack battery cell to everyone.

Mitacbattery 552125 soft-pack battery cell

Without further ado, let's take a look at the appearance of this battery cell first.

The Mitacbattery 552125 soft-pack battery cell is of a square structure as a whole, encapsulated with aluminum-plastic film, and the positive and negative sides are led out through wires.

The front of the Mitacbattery 552125 soft-pack battery cell is printed with relevant parameter words:

Model: ST 552125 and "+", "-" positive and negative pole markings;

Typical capacity: [email protected];

Nominal voltage: 3.8V Nominal energy: 1.33Wh

Internal resistance: ≤250mΩ.

The length of the Mitacbattery 552125 soft-pack battery cell is approximately 25.1mm.

The width of the Mitacbattery 552125 soft-pack battery cell is approximately 20.5mm.

The thickness of the Mitacbattery 552125 soft-pack battery cell is approximately 5.4mm.

The weight of the Mitacbattery 552125 pouch battery cell is approximately 5.7g.

The Mitacbattery 552125 soft-pack battery cell is relatively small in the hands of adults.

Soft-pack batteries, as they do not use hard shells, are more prone to heat dissipation. Therefore, in some cases, they may be more suitable for applications that require better heat dissipation than hard-shell batteries. Mitacbattery has a market share of over 10% in the TWS earphone battery market and more than 50% in the smart wearable battery market. It has successfully entered the ranks of first-tier enterprises with a market share of 4.55%. In terms of research and development direction, Mitacbattery focuses on innovative battery technologies, including fast-charging batteries, high-rate batteries, silicon anode batteries, and high-capacity batteries, etc. In terms of technical routes, the performance of batteries is continuously improved by adopting carbon nanotubes, optimizing the molecular weight of binders, and thinning foils.

Overall, pouch batteries, due to their flexibility, high energy density and lightweight design, are suitable for a wide range of fields, including but not limited to smart wearable devices, mobile electronic devices, portable energy storage devices and other areas that require flexible design and high energy density. Later, I Love Audio Network will bring you a detailed test of the Mitacbattery 552125 soft-pack battery cell. We will comprehensively analyze the performance of this battery from aspects such as charging and discharging, internal resistance, and temperature tests.
