In the present smart world, a lot of emphasis is placed on ecology. Also in terms of electronics and power. We often don’t realize how many things are powered by the energy generated by batteries. The list of battery applications and devices is virtually endless. In the article you will learn about standard solutions used globally and about the possibilities of battery customization.
EEMB – global manufacturer of battery solutions
EEMB is a Hong Kong-based battery manufacturer with 25 years of experience. Offers a wide range of battery power solutions for portable and stationary applications. The range includes products such as lithium ion, lithium polymer, lithium iron, lithium manganese and lithium thionyl. Thanks to such a diverse portfolio, customers can power devices that require the presence of batteries in virtually any application. EEMB’s production facilities are located in China. The factories have ISO 9001 and ISO14001 certificates, have their own quality and environmental management system, thanks to which they can provide reliable products that meet the strictest standards.

The most popular battery applications
The development of industry 4.0 and the increasing presence of all kinds of electronics in everyday life and in industry mean that batteries are gaining more and more new applications. The most popular battery-powered applications include:
- Energy, water, heat and gas meters
- GPS locators
- Temperature and humidity recorders
- NFC readers / recorders
- Logistic monitoring of materials at extremely low temperatures (e.g. transport of vaccines)
- Access modules / cards
- Emergency medical devices (e.g. inhalation applicators)
- Electronic medical capsules

Button and cylinder batteries
An example of the use of the popular CR2032 button battery is a water filtering device with a filling counter function and an LED diode informing about the need to replace the filter. It has a small electronic system that counts the number of opening the flap for pouring water. Inside there is a installed a disposable battery. It is soldered to the PCB module with personalized THT assembly.

In addition to standard solutions, button batteries for SMD and THT assembly are also personalized in accordance with the instructions received from the customer or with a standard size or arrangement of solder pins. The EEMB company specializes in this type of solutions and offers various versions of button batteries with a dedicated type of assembly. You can choose from 32 standard solutions.

Li-SOCl2 batteries and hybrid solutions
Batteries with the chemical composition of Li-SOCl2 (lithium-thionyl chloride) are installed in the measuring devices, also as a hybrid, i.e. a combination of the battery with a lithium capacitor according to the customer’s guidelines. Various variants are available.
The most popular versions of such battery solutions are: ER14250, ER14505, ER18505, ER26500, ER34615 with different terminals, cables or connectors.

The use of a lithium capacitor in conjunction with a battery gives the possibility of obtaining a higher pulse current and prevents passivation by draining the battery with a continuous, very low current. Passivation is a natural phenomenon found in Li-SOCl2 batteries. Thanks to this, the battery can work in the device for up to 20 years.

Quality and experience in battery production
In March 2018, a new facility with an area of 27,000 m² was officially commissioned. This new production facility, as well as the new automatic production line, have tripled EEMB’s production capacity. The whole is able to meet the growing demand of customers and satisfy their needs. Upgraded devices and a fully controlled environment in factories increase the efficiency and reliability of the batteries produced.
Continuous innovation at EEMB is supported by the high standards of research and design policy in a highly developed R&D department. The factories have quality certificates and meet the ISO 9001, UL, CE, ROHS, UN and IEC standards.
At the beginning of 2021, Masters entered into official cooperation with the global battery manufacturer EEMB. Masters offers a full range of EEMB portfolio in both standard and customized versions. Please contact us firstname.lastname@example.org.
