In 1999, the Global Industry Classification Standard (GICS) was developed by MSCI in collaboration with S&P Dow Jones Indices to provide an efficient, detailed and flexible tool for use in the investment process.
Batteries can be classified according to their chemistry or specific electrochemical composition, which heavily dictates the reactions that will occur within the cells to convert chemical to electrical energy. Battery chemistry tells the electrode and electrolyte materials to be used for the battery construction.
The number of categories has increased from three in the previous directive (portable battery, industrial battery and automotive battery) to five categories. The two new categories include Light Means of Transport (LMT) and electric vehicles. Figure 5: Battery types according to the new regulation
Primary batteries come in three major chemistries: (1) zinc–carbon and (2) alkaline zinc–manganese, and (3) lithium (or lithium-metal) battery. Zinc–carbon batteries is among the earliest commercially available primary cells. It is composed of a solid, high-purity zinc anode (99.99%).
The current designation system was adopted in 1992. Battery types are designated with a letter/number sequence indicating number of cells, cell chemistry, cell shape, dimensions, and special characteristics. Certain cell designations from earlier revisions of the standard have been retained.
Where the regulator disagrees with the classification of a battery, they will ask the battery producer to provide written confirmation from the battery manufacturer that its specific model number is designed exclusively for industrial or professional use.
This Classification Note provides requirements for approval of Lithium-ion battery systems to be used in battery powered vessels or hybrid vessels classed or intended to be classed with IRS.
