Lithium Manganese Button Battery

Lithium Manganese Button Battery

A button battery is a type of coin cell or portable electric battery. They are used for powering small electronic devices such as watches, calculators and hearing aids.

Lithium manganese button batteries are primary lithium batteries that use MnO2 as the anode. They have a high discharge capacity, long cycle life and low self-discharge. They are also very safe and environmentally friendly.


Ingestion of lithium manganese button batteries is a serious choking hazard. They can lodge in the nostrils, gullet (oesophagus) and throat and cause severe burns to the surrounding tissue. This can be fatal for young children.

To reduce the risk of ingesting lithium manganese button batteries, use them only on devices in accordance with their instruction manuals and handling precautions. Store or dispose of them safely in a place out of reach of children and pets.

Button cells are available in a variety of sizes and models. They can be found in quartz watches, calculators, small PDA devices, computer clocks and blinky lights.

They are commonly marketed by a letter prefix followed by four numbers to indicate the size, for example, CR2032 is a 3.2mm 3V battery. These batteries are also used in rechargeable devices, which may have a different prefix depending on the battery system.

Although many of these devices have secure compartments that are designed to keep children from gaining Lithium Manganese Button Battery access, they still pose a safety hazard. Batteries are easily freed from the compartment when the device is dropped or broken, allowing a child to enter the battery cavity and possibly ingest or insert a button cell.

These types of cells are not regulated as hazardous waste in the United States, but they may be in a municipal disposal stream. For example, one manufacturer of “button” size lithium iron disulfide primary batteries advises that consumer quantities of used cells are disposed of in municipal waste.

Lithium-ion batteries have become more energy dense over the years, with a separator thickness of only 20-25um. As a result, a nail penetration test that could be tolerated on older 18650 cells with a capacity of 1.35Ah would be a bomb on today’s 2.4Ah battery.

In addition to requiring the safe use of these batteries, CPSC staff proposes that manufacturers and importers of button cell or coin batteries must notify consumers of any additional performance data related to the safety of these products at the point of sale, both online and in stores. If the rule is finalized, these notification statements will be included on the product packaging and accompanying literature that comes with these products.


The environment is a critical concern for all battery users. Various hazardous chemicals can leak from lithium-ion and lithium-polymer batteries into the soil or water, where they can cause problems for human health and environmental quality.

Button batteries can also be a choking hazard for young children, so they should be stored away from them. They can be swallowed or push up through the nose or gullet, and can cause serious burns if they lodge in the throat.

Despite their size and appearance, these batteries can contain toxic materials such as lead, mercury, cadmium, or acid that can leak into the surrounding air. These chemicals can pose a health risk to children and adults, and the toxicity of some can be harmful to plants and animals.

These types of batteries are used in many different products, including security alarm devices and shared bicycle electronic locks. They are also used in medical equipment, and are suitable for a wide range of applications because they have strong power and a long working life.

They are a great alternative to conventional batteries for many devices, because they offer better performance at a low cost. They can be recharged and reused, and their energy density is higher than that of most other batteries.

In addition, they are safer than traditional batteries and can be easily disposed of. The materials in the Lithium Manganese Button Battery are derived from a zinc-manganese oxide cathode and a lithium anode.

Batteries with this chemistry are commonly found in electronic items such as handheld digital cameras, laptop computers, and smartphones. They are also used in emergency lighting systems.

The lithium manganese button battery is a popular alternative to traditional batteries because it offers superior performance at a low price and has a long working life. It can be charged and discharged quickly, and its internal cell resistance is low, allowing fast charging and high-current discharging.

The toxicity and resource depletion potentials of the lithium batteries analyzed in this study were assessed using standardized leaching tests, life-cycle impact assessment (LCIA), and hazard assessment models. The results of these studies identify metals, Co, Cu, Ni, and Pb that are a significant source of hazardous chemicals in the environment. They suggest that improvements to design-for-the-environment (DfE) strategies should focus on reducing the concentration of these hazardous chemicals.


A Lithium Manganese Button Battery is used in small devices and electronic products, including cell phones, clocks, digital cameras, thermometers, flashlights, calculators, personal computers (BIOS) and remote car locks. They are also used in some medical equipment.

They are made from lithium, manganese dioxide, and a small amount of copper and nickel. They have several benefits, such as high working voltage and low self-discharge rate. This makes them the most popular rechargeable battery for consumer electronics.

The cost of a lithium manganese battery varies based on the different parameters, such as capacity, power, and charging/discharging. Generally, they cost from 0.036 to 2.23 for each battery.

Compared with other types of batteries, lithium manganese batteries are cheaper to produce. They also have a higher energy density and better power output.

However, they can be difficult to handle and are not safe for children to use. They can be easily swallowed, causing serious injury or even death when a child aspirates or chokes on them.

The environmental pollution of batteries is a major concern. The mercury content of button batteries is quite high, which means they are a major source of environmental pollution. Therefore, it is important to properly dispose of these batteries.

It is a good idea to store used batteries in a safe, room temperature area out of reach of children and pets. Batteries should not be stored in the sunlight or near heaters, as this can cause corrosion and deterioration of their internal components.

These batteries should also be handled carefully, as they contain sulfuric acid, which can irritate the skin and cause burns. If you plan on storing your batteries for long periods of time, it is best to protect them with plastic wrap or a lid to prevent them from rusting and becoming dangerous.

Lithium manganese batteries are available in a variety of sizes and shapes, but the most common ones are the 3-volt “coin” type. These are often referred to as CR2032 or CR2025. They are 20 mm in diameter and 3.2 mm thick. These batteries are not regulated by the US Federal government for disposal.


Lithium manganese button batteries are used in a variety of products. They are used for portable devices, such Lithium Manganese Button Battery as radios, flashlights, and toys. They also find application in the medical industry.

They are available in several shapes and sizes, and they can be recharged or replaced. They are also very lightweight and compact, which makes them ideal for small electrical appliances.

The most common type of lithium battery is the Li-Mn battery. These batteries are based on the lithium manganese oxide chemistry and have many advantages over conventional lithium batteries.

For example, they are more durable, have a longer service life, and are more energy-efficient. They are also more environmentally friendly, as they contain less mercury than lead-acid batteries.

These batteries are also cheaper than other types of lithium batteries. They are used in a wide range of applications, including electronic dictionaries and timepieces. They are also a popular choice for laptop computers.

However, they can cause serious injury or death if they are accidentally ingested. Children who are 5 years and younger are most at risk.

A number of different safety measures are in place to prevent this type of incident from occurring. For example, children should never put a button battery in their mouth. This can result in severe damage to their esophagus and stomach.

Additionally, buttons should not be stored near water or exposed to sunlight. This can lead to the release of toxic chemicals into the environment.

Another concern is the presence of hazardous substances such as lead, cadmium, and acid in the batteries. These can pollute the soil and water if they are not properly removed before disposing of them.

These are important issues to consider when designing a product that uses button batteries. They are also important in the management of the battery supply chain.

A lithium battery can be a good option for some electronic devices, such as medical instruments and pacemakers. However, it may not be the best choice for other devices. This is because the battery may not last as long as expected, and it could cost too much to replace it.
