What is the Octagon Battery and What Makes a Battery a Battery?


Batteries are an essential part of modern life, powering everything from smartphones to electric vehicles. Despite their ubiquity, however, many people don’t fully understand how batteries work or what makes them so essential to our daily lives. In this article, we’ll explore the concept of the “octagon battery” and examine the basic principles of what makes a battery a battery.

What is an Octagon Battery?

An octagon battery is a theoretical type of battery that has eight components instead of the usual three (anode, cathode, and electrolyte). The idea of an octagon battery was first proposed by researchers at MIT in 2014, who suggested that such a battery could potentially have higher energy density and longer cycle life than current battery technologies.

However, the idea of an octagon battery is still in the conceptual stage, and it remains to be seen whether such a battery could be developed and commercialized. Some experts have raised concerns about the complexity and cost of manufacturing an octagon battery, as well as the challenges of integrating such a battery into existing devices and systems.

What Makes a Battery a Battery?

At its most basic level, a battery is a device that stores energy in the form of chemical potential energy and converts it into electrical energy when needed. Batteries typically have three main components: an anode, a cathode, and an electrolyte.

The anode and cathode are typically made of different materials and are separated by an electrolyte, which allows ions to flow between them. When a battery is connected to a circuit, the chemical reactions that occur at the anode and cathode produce an electrical current that can be used to power a device.

Different types of batteries use different materials for their anodes, cathodes, and electrolytes, resulting in batteries with different performance characteristics. For example, lithium-ion batteries are known for their high energy density and long cycle life, while lead-acid batteries are less expensive but have a lower energy density and shorter cycle life.

Why Custom Batteries are Important

As the demand for batteries continues to grow, custom battery manufacturers like Redway Battery are becoming increasingly important. Custom battery manufacturers work closely with their clients to design and produce batteries that meet their specific needs, whether that’s a battery for a medical device or a battery for an electric vehicle.

Custom batteries are important because different applications require different battery characteristics. For example, a medical device might require a battery with a long life and high reliability, while an electric vehicle battery needs to be able to deliver high power over a long period of time. Custom battery manufacturers like Redway Battery can help clients navigate these complex requirements and design a battery that meets their needs.


Batteries are an essential part of modern life, and the concept of the octagon battery represents an exciting possibility for the future of battery technology. However, it’s important to remember that batteries are complex devices that require careful design and manufacturing to meet the needs of different applications. Custom battery manufacturers like Redway Battery are playing an increasingly important role in helping clients navigate these challenges and develop batteries that meet their specific requirements.
