CR2032 Coin Cell Cases


Today most of the electronic devices use battery to work. Coin cell batteries are used to power small, portable electronics devices like the keyless entry remote for your car, laser pointers, pocket calculators, implantable cardiac defibrillators and even artificial cardiac pacemakers. We have to protect batteries to have a long-life device. Coin cell cases are just designed for this purpose. The main advantage of a coin cell case is to protect your battery.
A well-designed coin cell case must resist shocks and vibrations while remaining flexible enough to allow easy battery replacements. The best coin cell cases have features designed to ease battery removal, which allows for the use of stronger plastics while keeping battery replacements simple.
Durability is especially important for applications where frequent battery replacements may be needed over the product’s expected lifespan. If a coin cell case’s contacts have an especially strong grip, the increased wear and tear on the contacts during battery insertions and removals can cause significant harm to the metal. If an application will require relatively frequent cell changes, find out the cycle count that the case has been tested for. It is also worth noting that a large number of replacements will lead to more instances of end users inserting batteries with the polarities reversed, so holders with built-in reverse polarity protection features would be beneficial as well.
Another little known fact is that competing brands of batteries can differ substantially in terms of dimensional specifications. For example, according to ANSI and IEC standards a CR2032 coin cell can vary in height by ±0.3 mm, or almost 10% of its total height. Therefore, it is critical that a coin cell case be adaptable to normal height variances while not accepting incompatible batteries, but it is of course completely unacceptable to have a connection that is too loose, as it compromises electrical performance and battery retention.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
