7 Foreword When they are offered for transport, lithium batteries are regulated as Dangerous Goods by the United Nations Transport Organisation and other national transport authorities. This regulation is being permanently adapted to take into consideration the evolution of lithium battery technologies. Indeed, lithium metal battery markets have seen significant developments in the last twenty years. More recently, a similar evolution has been observed with the increasing role played by rechargeable Lithium-ion batteries in electrical and electronic equipment. Battery technology innovation and development helps an increasing number of technicians and engineers to design new equipment powered by portable sources of energy such as lithium batteries. The innovation capacity offered by lithium batteries opens the way to an increasing use of advanced rechargeable batteries in our modern society. The necessity for an increasing number of economic actors to respect the UN Dangerous Goods Regulation requires modern communication tools to inform the shippers of batteries about their duties and responsibilities when offering them for transport. The aim of this manual is to offer a simple and visual means to access the UN Regulation via a modern multimedia communication tool. The regulation is presented in a summarized format covering ground, air and maritime transportation modes. In a page opposite the various regulations, the packaging and labelling instructions are illustrated to facilitate the implementation of the transport regulation as well as the packaging and labelling requirements by the shipper of lithium batteries. The objective of the funding Associations is to offer access to the UN Transport Regulation to the largest number of interested parties in order to make them aware of their duties and responsibilities when shipping lithium metal or lithium ion batteries. We thank Dr. Marco Ottaviani for preparing this exhaustive document with the most updated information and Emanuele Fanizzi, the Editor, who has accepted to translate the information into modern multimedia tools accessible to the largest number of users.
