History of 14500 Battery Size #

The 14500 battery size is a standard size for lithium-ion cells, which were first introduced to the market in 1991. Prior to this, small cylindrical cells were available in sizes such as AA, AAA, and C, but the 14500 was the first of its kind. It is a relatively new form factor, but has become popular due to its small size and high capacity.

Typical Chemistry of 14500 Battery Size #

The 14500 battery size typically uses a lithium-ion chemistry, which is one of the most popular types of rechargeable batteries available today. Lithium-ion cells offer high energy density, low self-discharge rate, and no memory effect. The cells can be charged and discharged hundreds of times without significant degradation of performance.

The typical chemistry of the 14500 battery size is a 3.7V nominal voltage with a capacity of 700mAh to 1300mAh. The cells are typically made of a lithium-cobalt-oxide (LiCoO2) cathode and a graphite anode. The cells are also available in different shapes and sizes, such as flat, prismatic, and cylindrical.

Typical Use of 14500 Battery Size #

The 14500 battery size is most commonly used in small electronic devices such as digital cameras, portable media players, and handheld game consoles. The small size and high capacity of the cells make them ideal for these types of devices, as they can provide a longer runtime than traditional AA or AAA batteries.

The 14500 battery size is also popular for use in flashlights and other small LED lighting devices. The cells can provide a brighter and longer lasting light than traditional batteries, making them ideal for camping, hiking, and other outdoor activities.

Design of 14500 Battery Size #

The 14500 battery size is designed to be small and lightweight, while still providing a high capacity. The cells are typically made of a lithium-cobalt-oxide (LiCoO2) cathode and a graphite anode, which allows them to be charged and discharged hundreds of times without significant degradation of performance.

The cells are also available in different shapes and sizes, such as flat, prismatic, and cylindrical. This allows them to be used in a variety of different devices and applications. The cells are also designed to be safe and reliable, with built-in safety features such as overcharge protection and short circuit protection.
