Lithium-manganese-dioxide (LiMnO2)

History #

The lithium-manganese-dioxide (LiMnO2) battery chemistry was first developed in the late 1970s by the Japanese company Sanyo. The company was looking for a way to improve the performance of their lithium-ion batteries, which had been used in consumer electronics since the early 1970s. The LiMnO2 chemistry was designed to provide a higher energy density than other lithium-ion chemistries, as well as improved safety and reliability.

Since its introduction, LiMnO2 has become one of the most popular battery chemistries for consumer electronics, and is now used in a wide range of products from mobile phones and laptops to electric vehicles and medical devices.

Typical Use #

LiMnO2 batteries are used in a variety of applications, including consumer electronics, electric vehicles, and medical devices. In consumer electronics, LiMnO2 batteries are used in mobile phones, laptops, and other portable devices. They are also used in electric vehicles, such as electric bicycles and scooters, as well as in medical devices such as pacemakers and insulin pumps.

In consumer electronics, LiMnO2 batteries are typically used in rechargeable devices, such as mobile phones and laptops. They are also used in some non-rechargeable devices, such as digital cameras and watches.

In electric vehicles, LiMnO2 batteries are used to power the motor and provide energy storage. They are typically used in combination with other battery chemistries, such as lithium-ion and lead-acid, to provide a more efficient and reliable power source.

In medical devices, LiMnO2 batteries are used to power pacemakers and insulin pumps. They are typically used in combination with other battery chemistries, such as lithium-ion and nickel-metal-hydride, to provide a more reliable and efficient power source.

Design #

LiMnO2 batteries are typically designed with a cylindrical shape, similar to other lithium-ion batteries. The cells are typically made up of a positive electrode (cathode) made of lithium-manganese-dioxide, a negative electrode (anode) made of graphite, and a separator between the two electrodes. The cells are then sealed in a metal or plastic case.

The design of LiMnO2 batteries is optimized for high energy density and safety. The cells are designed to be lightweight and compact, while still providing a high energy density. The cells are also designed to be safe, with built-in safety features such as overcharge protection and short-circuit protection.

LiMnO2 batteries are typically designed with a nominal voltage of 3.6V and a capacity of up to 3Ah. The cells are typically rated for up to 500 charge/discharge cycles, and can be recharged up to 1000 times. The cells are typically rated for temperatures between -20°C and 60°C.
