Lithium Manganese Dioxide Battery-Introduction and Application

Not surprisingly, lithium-ion batteries are critical to today's technology. In fact, lithium-ion batteries are commonly found in every portable device, even in electric cars. Laptops, smartphones, cordless power tools, tablets and flashlights are just a few examples of the kind of technology powered by this remarkable battery that has been the foundation of electronics since its commercialization in 1991. These batteries are hugely popular because they can equip a large amount of energy into a very small space and are quite light in weight.

Like other batteries, lithium-ion batteries provide the same elements within the cell in order to produce energy from a chemical reaction - the negative electrode, the positive electrode and the electrolyte. Like other technologies, lithium-ion batteries have undergone significant changes over time, including new chemicals used to improve performance and for different applications.

In this article, we'll discuss lithium manganese dioxide batteries. So let's start uncovering things you may not have known about lithium manganese dioxide batteries before.

What is a lithium manganese dioxide battery?

Lithium manganese dioxide batteries (Li-Mn02) are preferably used as primary or standard batteries. These batteries are available in both coin and cylindrical types. It is a highly reliable and lightweight battery with a voltage of 3.0v that can operate at several different temperatures. They are known for providing high voltage, low internal resistance, stable discharge rate and high specific energy.

Lithium manganese dioxide batteries have a positive active component of manganese dioxide (Mn02) and a negative active component of lithium (Li) and an organic electrolyte solution.

The following are its main highlights -

High voltage - At a nominal voltage of 3.0 volts, it has approximately twice the nominal voltage of alkaline and silver oxide batteries.

Suitable for a wide temperature range - The battery can operate over a wide temperature range of -40 degrees Celsius to +85 degrees Celsius.

High energy density - The battery's electrochemical system has the high energy density of available primary cells, up to 400 Wh/KG.

Long shelf life and long service life - Lithium manganese dioxide batteries have very low self-discharge, which is why these batteries can complete a ten to twenty year service life and support a long storage period.

Outstanding Safety - These batteries are regularly reviewed by Underwriters Laboratories and are fully compliant with UN shipping test needs or requirements.

Sealed Enclosures - There is no doubt that sealed enclosures are necessary for the long shelf life and safety of the products using the batteries. Glass-to-metal seals are used for the insulated + (positive) terminals and safety vents are used on the screw-type negative terminals.

That's all there is to know about lithium manganese dioxide batteries. Understanding the key characteristics of the battery will help you determine if it is suitable for your application. Most importantly, make sure you buy your battery from a reputable and trustworthy manufacturer. Choosing any one of them could expose you to worse consequences.

Are lithium manganese dioxide batteries rechargeable?

There are coin-type lithium manganese dioxide rechargeable batteries available, which are lightweight and compact rechargeable batteries. The battery uses a specially treated lithium-aluminum composite (for the negative terminal) and manganese dioxide (for the positive terminal) and an organic electrolyte to produce excellent discharge characteristics and low self-discharge.

The following are some of the characteristics of lithium manganese dioxide rechargeable batteries -

The operating voltage of the battery is approximately twice that of a NiCd rechargeable battery. Shows a high discharge voltage of 2.8 volts at 10% of nominal capacity.

Excellent discharge and charge cycle characteristics

Superb leakage resistance and low self-discharge

Excellent float characteristics - features a specially designed organic electrolyte that provides stable discharge characteristics even when the battery is charged at 3.3 volts for one year at 20 degrees Celsius

Excellent high rate discharge characteristics

What are the uses of lithium manganese dioxide batteries?

Let's get into a very interesting topic when it comes to batteries. You are certainly curious to know the applications of lithium manganese dioxide batteries. Aren't you, right? Without a doubt, this is the first thing most of us look at or search for when we buy batteries.

Well, the typical application for these batteries is to provide memory or microcontroller backup power in the event of rechargeable battery depletion or power failure.

However, let's take a quick look at the applications for lithium manganese dioxide batteries -

Laptops

Desktop computers

Calculators

Watches

Portable gaming devices

Electronic dictionary

Keyless entry system

Remote control

Camcorder

Communication labels

Digital Cameras

OA machines - printers, copiers and faxes

Medical devices and cash registers

FA instruments - sensors, on-board microcomputers and measuring instruments

Electronic Instruments - Electricity, gas, and water.

Not to mention that batteries include organic solvents, lithium and other combustible elements. Considering all these factors, improper handling of these batteries may lead to leakage, deformation, explosion or fire. Therefore, make sure to keep these batteries out of reach of children.

And, if you are considering a primary battery or a lithium manganese dioxide battery (which cannot be recharged), then there is one thing to make sure of. If the battery is used for RTC backup or storage applications, then make sure you use a diode to prevent charging from the mains and a protective resistor to regulate the current.

Be sure to read this article before you make your final decision to purchase a lithium manganese dioxide battery. This will help you understand what lithium manganese dioxide batteries are all about. Most importantly, if the battery is right for your application.
