Abstract
In the rapidly evolving landscape of wireless trackers and Internet of Things (IoT) devices, the selection of an appropriate battery is of paramount importance. These devices, often operating without external wiring and relying solely on built-in power sources, demand batteries that can offer long - lasting performance, high energy density, and reliability. This article focuses on two prominent battery types used in this domain: LiSOCl₂ batteries and ultra - thin batteries (including ultra - thin LiMnO₂ and ultra - thin LiPo batteries). By examining their characteristics, advantages, limitations, and suitability for wireless trackers and IoT devices, we aim to provide a comprehensive guide for manufacturers, developers, and end - users.
1. Introduction
The proliferation of wireless trackers and IoT devices has transformed various industries, from logistics and asset management to personal safety and smart home applications. These devices are designed to operate autonomously, transmitting data and performing functions without the need for external power connections. As a result, the battery becomes the lifeblood of these devices, determining their operational life, performance, and overall usability.
The requirements for batteries in wireless trackers and IoT devices are unique. They need to have a long shelf life, high energy density to support continuous or intermittent operation, and the ability to withstand a wide range of environmental conditions. Additionally, factors such as size, weight, and cost also play crucial roles in battery selection. Among the various battery options available, LiSOCl₂ batteries and ultra - thin batteries have emerged as the most widely used choices.
2. LiSOCl₂ Batteries: The Powerhouse for Long - Lasting Performance
2.1 High Energy Density: A Key Advantage
LiSOCl₂ (Lithium Thionyl Chloride) batteries are renowned for their exceptionally high energy density. Energy density refers to the amount of energy a battery can store per unit volume or mass. In the context of wireless trackers and IoT devices, where space is often at a premium, a high - energy - density battery is essential.
LiSOCl₂ batteries achieve their high energy density through a unique chemical reaction. The lithium anode reacts with thionyl chloride (SOCl₂) as the cathode material, releasing a large amount of electrical energy. This high energy density allows LiSOCl₂ batteries to power wireless trackers for extended periods, often lasting several years on a single charge. For example, in asset tracking applications where devices may be deployed in remote locations for long - term monitoring, LiSOCl₂ batteries can provide reliable power without the need for frequent battery replacements.

LiSOCl₂ batteries are well - suited for such conditions as they can operate effectively over a wide temperature range, typically from - 40°C to 85°C.
This wide operating temperature range ensures that the trackers continue to function reliably regardless of the external environment. For example, in cold chain logistics, where temperature - sensitive goods are transported, LiSOCl₂ - powered trackers can accurately monitor the temperature and location of the shipment even in sub - zero temperatures. Similarly, in industrial IoT applications, such as monitoring equipment in hot factories, these batteries can withstand high temperatures without compromising performance.
2.4 Long Service Life: Reduced Maintenance and Cost
Due to their high energy density, low self - discharge rate, and wide operating temperature range, LiSOCl₂ batteries offer a long service life. In wireless trackers, the service life of the battery is closely related to the set positioning frequency. However, even with relatively frequent positioning, LiSOCl₂ batteries can last for several years.
This long service life translates to reduced maintenance requirements and lower overall costs. Manufacturers and end - users do not have to frequently replace batteries, which saves on both the cost of batteries and the labor associated with battery replacement. For large - scale deployments of wireless trackers, such as in fleet management or asset tracking systems, the long service life of LiSOCl₂ batteries can result in significant cost savings over the lifetime of the devices.
3. Ultra - Thin Battery: Meeting the Demands of Size and Flexibility
