Lithium Manganese Dioxide Battery-Introduction and Application

Lithium Manganese Dioxide Battery-Introduction and Application

Page view

There is no surprise that a lithium-ion battery is vital to today’s technology. In fact,  lithium-ion battery are commonly found in every portable device and even, in electric vehicles. Laptops, smartphones, cordless power tools, tablets, and flashlights are a few instances that are powered by this outstanding battery technology, which has been a foundation of electronics since their commercialization back in the year 1991. This battery’s huge popularity is because of their ability to equip a remarkable amount of energy into a significantly small space with quite low weight.

Like other batteries, lithium-ion provides the same elements inside the battery cell in order to generate energy from a chemical reaction - a negative electrode, a positive electrode, and an electrolyte. Like other technologies, the lithium-ion battery has significantly evolved with time, including new chemistries for increased performance and different applications.

In this post, we are going to talk about lithium manganese dioxide battery. So, let’s begin to unveil the things about lithium manganese dioxide battery you may don’t know before.

What is lithium manganese dioxide battery?

Lithium manganese dioxide battery (Li-Mn02) is preferred as a primary or standard battery. These batteries come in both coin and cylindrical types. It is highly-reliable and light batter with a voltage of 3.0v and can work under several different temperatures. They are known for delivering high voltage, low internal resistance, a stable discharge rate, and high specific energy.

The positive active component of lithium manganese dioxide battery is Manganese dioxide (Mn02), the negative active component is Lithium (Li) and an organic electrolyte solution.

Here are its key highlights -

  • High voltage - At a nominal voltage of 3.0 volts, it features about twice the nominal voltage of alkaline and silver oxide batteries.

  • Suitable for wide temperature range - the battery can operate under a wide range of temperatures generally from -40 degrees Celsius to +85 degrees Celsius.

  • High energy density - The battery’s electrochemical system features a high energy density of available primary batteries, up to 400 Wh/KG.

  • Superlative shelf life and long operating life - The self-discharge of lithium manganese dioxide battery is very low and that’s why these batteries can accomplish a service life of ten to twenty years and support very long storage periods.

  • Outstanding safety -These batteries are regularly reviewed by Underwriters Laboratories and completely meet UN transportation test needs or requirements.

  • Hermetically sealed case- No doubt, the hermetically sealed case is necessary for the long shelf life and safety of the products in which batteries are utilized. A glass-to-metal seal is utilized to insulate the + (positive) terminal and a safety vent is utilized on the negative terminal for spiral type.

That’s all about lithium manganese dioxide battery. Comprehending key characteristics of the battery will help you determine whether it is the right fit for your application or not. On top of all, make sure to buy the battery from a reputable and trustworthy manufacturer. Picking any random one could make you face further worse consequences.

Are lithium manganese dioxide batteries rechargeable?

There is the availability of a coin-type lithium manganese dioxide rechargeable battery, which is a lightweight and small rechargeable battery. The battery features specially treated a lithium-aluminum composite for the negative terminal and manganese dioxide for the positive one and an organic electrolyte that yields outstanding discharge traits with low self-discharge.

Here are some traits of lithium manganese dioxide rechargeable battery-

  • The operating voltage of the battery is about the twice of nickel-cadmium rechargeable batteries. Shows a high discharge voltage of 2.8 volts when at ten percent of nominal capacity.

  • Superior discharge and charge cycle characteristics

  • Superlative leakage resistance and low self-discharge

  • Outstanding floating characteristics - a specially designed organic electrolyte is featured to deliver stable discharge traits even if the cell charged for one year at 3.3 volts at 20 degrees Celsius.

  • Outstanding high rate discharge traits

What is lithium manganese dioxide battery used for?

Let’s get into a very interesting subject when it comes to batteries. You certainly are so curious to know about the applications of lithium manganese dioxide battery. Isn’t, it right? Without a doubt, it is the first thing that most of us look or search when it comes to buying a battery.

Well, a typical application of these batteries is to offer memory or microcontroller backup power in case of rechargeable battery depletion or power failures.

However, let’s give a quick look at the applications of lithium manganese dioxide battery-

  • Notebook PCs

  • Desktop PCs

  • Calculators

  • Watches

  • Portable Game devices

  • Electronic dictionaries

  • Keyless entry systems

  • Remote controllers

  • Camcorders

  • Communication tags

  • Digital still cameras

  • OA Machines - Printers, Copiers and Fax

  • Medical instruments and cash registers

  • FA instruments - sensors, onboard microcomputers and measuring instruments

  • Electronic meters - electricity, gas, water.

Not to mention, the battery includes organic solvents, lithium, and other combustible elements. Considering all these things, improper handling of these batteries could cause leakage, distortion, explosion, or fire. So, make sure to keep these batteries out of reach of kids.

Moreover, if you are considering the primary battery or lithium manganese dioxide battery (that can’t be charged), then there is one thing to ensure. It is that if the battery used in RTC backup or memory applications then ensure to use diodes in order to prevent charging from the primary power source and use a protective resistor for regulating the current.

Before you make your final decision to buy lithium manganese dioxide battery, make sure to go through this post. This will help you get an idea of what lithium manganese dioxide battery is all about. Most significantly, if the battery is appropriate for your application.
