A secondary cell is a [galvanic cell](/entry/_2azW7zIxVCeNrbXuRrsm2k) that can also be used as an [electrolytic cell](/entry/_2uDtUtOWJCL33X7zTAK8dK); in other words, it can be charged, then used to supply electrical energy to a device, then charged again. Rechargeable batteries are comprised of one or more secondary cells, as opposed to disposable batteries which are comprised of [primary cells](/entry/_7OCTF7b5Z4wM7KvEE16OtK).

The TROES 240 kWh cabinet is a lithium-ion battery energy storage system ([BESS](/entry/_5yfaUcmCgtN6K9FDNKdjbp)) for use outdoors. The system is contained in a 10 foot long enclosure. It is supported by HVAC, thermal runaway protection, power conversion systems, and cloud-based operation. The cabinet may also contain fire suppression systems. It is designed by Canadian battery designed and manufacturer [TROES Corp.](/entry/_4q8GTHzdDLFcvfEbtc9kqB).

A galvanic cell, also known as a voltaic cell, is an [electrochemical cell](/entry/_3VVHFqLRvQtI1YzMP7OxVV) that generates electrical energy through chemical reactions, specifically redox reactions. Galvanic cells are the building blocks of [batteries](/entry/_5HYZND6114KVUtCGjFC8mT).

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).

The TROES 2437 kWh cabinet is a lithium-ion battery energy storage system ([BESS](/entry/_5yfaUcmCgtN6K9FDNKdjbp)) for use outdoors. The system is contained in a 20 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).

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 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).
