They are manufactured by [Tesla Energy](/entry/_27PVRRLDkKIBKhxcgh1U3q), the clean energy subsidiary of [Tesla, Inc](/entry/_27DEebL0FX8pdOLEws9e7R). The Powerpack stores electricity for time of use load shifting, backup power, demand response, microgrids, renewable energy integration, frequency regulation, and voltage control.^[Some text from Wikipedia, ["Tesla Powerpack"](https://en.wikipedia.org/wiki/Tesla_Powerpack)]

An electrolytic cell is a [cell](/entry/_3VVHFqLRvQtI1YzMP7OxVV) containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen).

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. Those which generate electrical energy are called galvanic cells, and are the principal buidling block of [electric batteries](/entry/_5HYZND6114KVUtCGjFC8mT).

A lithium-ion cell is a [secondary cell](/entry/_4HwJfgRjCzfOI7z2XTzY0r) ("rechargeable battery") that uses a lithium compound as its cathode (positive terminal) material, and typically graphite as the anode (negative terminal) material. Lithium-ion cells feature high energy density and low self-discharge, making them ideal for a variety devices including mobile phones and electric vehicle batteries.

The **Tesla 18650 cell** is a proprietary [18650 cylindrical lithium-ion](/entry/_7RHY0mKlOEp2xsahAaNcbc) [cell](/entry/_4HwJfgRjCzfOI7z2XTzY0r) developed by Tesla and Panasonic. It is thought to be similar to the [Panasonic NCR18650BE cell](/entry/_1CZTpr2BFC76f54Q3vNuB4).

The TROES 4874 kWh cabinet is a lithium-ion battery energy storage system ([BESS](/entry/_5yfaUcmCgtN6K9FDNKdjbp)) for use outdoors. The system is contained in a 40 foot long enclosure. It is supported by a fire suppression system, HVAC, thermal runaway protection, power conversion systems, and cloud-based operation.  It is designed by Canadian battery designed and manufacturer [TROES Corp.](/entry/_4q8GTHzdDLFcvfEbtc9kqB).

The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries,  including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion).  The design has this name because the cross section of the battery looks like a Swiss roll ^[from Wikipedia, ["Jelly roll"](https://en.wikipedia.org/wiki/Jelly_roll_(battery))].

A 4680 cell is a [cylindrical lithium-ion](/entry/_75HaEKOi2Ir5UV84KH3CGk)
[cell](/entry/_4HwJfgRjCzfOI7z2XTzY0r), with a diameter of {this.get(prop=[[/prop/_3JjzqBJ9YLtRGuesdK0lWb]])}
and a length of {this.get(prop=[[/prop/_1PPhmzTVqhSwjbyZtAsIBm]])}.
The cell was announced at Tesla's battery day in 2020, along with plans for the cell to power future Tesla vehicles.
Chinese battery manufacturer BAK later announced a 4680 model, with unknown chemistry. 
It is significantly larger than its predecessors, with a diameter more than twice that of the
[18650 cell](/entry/_7RHY0mKlOEp2xsahAaNcbc) (which powered the [Tesla 85kWh Battery](/entry/_6dF6GUIrPx8ToREmsFAZ5R)), 
and the [21700 cell](/entry/_725MCg9IOqXqKUUA2cEoSc).
Because of this, the 4680 cell boasts a significantly higher storage capacity of {this.get(prop=[[/prop/_7jO8Fx7LRlDUKaEXBSCYjI]])}.

The **21700 cell** (also called **2170 cell**) is a [cylindrical lithium-ion](/entry/_75HaEKOi2Ir5UV84KH3CGk) [cell](/entry/_4HwJfgRjCzfOI7z2XTzY0r) introduced in 2017 by Panasonic. With a diameter of 21mm and a length of 70mm, it is slightly larger than the standard [18650 cell](/entry/_7RHY0mKlOEp2xsahAaNcbc). Due to its larger area and a smaller separation between the anode and cathode, the 2170 boasts a larger capacity than the [18650 cell](/entry/_7RHY0mKlOEp2xsahAaNcbc). The 2170 cell is used in the Tesla Model 3 and Y vehicles, and the [Tesla Powerwall 2](/entry/_LmaF231kKLrJmYWeVZ8qS) and [Powerpack 2](/entry/_3XaDmRIYYb0F01anoSHKLj).

A cylindrical [lithium-ion cell](/entry/_5GDsp3jxMTJ1liBePo9sgT) is a cylindrical [cell](/entry/_5GDsp3jxMTJ1liBePo9sgT) made from a single long "sandwich" of the positive electrode, separator, negative electrode, and insulating sheet which is then rolled and inserted into a hollow cylinder casing. This cell design is often called a "[jelly roll](/entry/_6hMuZdGzPja2AoKOTo4hiH)" or "swiss roll" because the cross section looks like a swiss roll.

An 18650 cell is a standard format [cylindrical lithium-ion](/entry/_75HaEKOi2Ir5UV84KH3CGk)
[cell](/entry/_4HwJfgRjCzfOI7z2XTzY0r), with a diameter of {this.get(prop=[[/prop/_3JjzqBJ9YLtRGuesdK0lWb]])}
and a length of {this.get(prop=[[/prop/_1PPhmzTVqhSwjbyZtAsIBm]])} (slightly larger than a
[AA battery](/entry/_1bWGkkQDaPxHwmcMkO5cbu)).
The 18650 cell has been used since the late 1990s and has been popular for a wide range of applications that
require a rechargeable battery - such as flashlights, laptops, power tools, and even electric vehicles. Due
to the popularity of the 18650 cell, they are usually an easily available, well-understood, and affordable
option.

The length is a measurement or specification of the size of an object, usually as measured along its longest major axis.

Length

The quantity of matter in a physical body, which directly affects how heavy something is. Often called "weight", though the technical definition of weight is different.

Mass

A battery's capacity is the amount of electric charge it can deliver at the rated voltage. As individual batteries can vary significantly, a nominal capacity is usually given.

Battery Capacity (minimum)

The diameter is a measurement or specification of the distance across a circular or spherical shape (specifically, the length of a straight line passing through the center and connecting two points on the circumference).

Diameter

Nominal voltage is the value assigned to an electrical component or system to indicate its typical voltage. The actual voltage that the component or system operates at may vary significantly from the nominal voltage.
