The market 7 1. Manufacturer’s data 3. An exploding market FOCUS In 2006, 40 billion disposable batteries were sold worldwide. In 2006, the rechargeable battery market in Europe accounted for 92 million units2. It is currently undergoing remarkable growth. Consequently, rechargeable batteries are taking their place in major consumer retail outlets and specialised outlets. Key figures on the growth of rechargeable batteries between 2005 and 2006 1 EUROPE The rechargeable market vs. disposable batteries: + 20 % in volume + 10 % in value

How do rechargeable batteries work? How can their use be optimised and how can we reduce their impact on the environment? <strong>UNIROSS</strong> proposes a quick user’s manual. I Disposable battery, rechargeable battery, what changes? There are two types of batteries: Single-use batteries, called disposable batteries, which contain a quantity of energy that is not renewable and which have a single life cycle, since they are thrown away after each use. Rechargeable batteries can be recharged using a charger. They have a multiple life cycle and are recharged after each use. What happens inside a rechargeable battery? A rechargeable battery is made up of various sheets of components superposed and rolled up like the tobacco leaves in a cigar. At each extremity of the rechargeable battery, two electrodes are connected through an ionically conductive solution called an electrolyte. From chemical energy to electric energy Each time it is recharged, a rechargeable battery transforms electric energy into chemical energy. When a device needs energy, the rechargeable battery converts the chemical energy back into electric energy. This is where there is a radical difference between disposable batteries and rechargeable batteries: whereas the former finish their life cycle and are thrown F away or head for recycling, the latter can be recharged hundreds of times with chargers. What is the capacity of a rechargeable battery? The capacity of a rechargeable battery is the quantity of energy that it can store, and release to power a device. It is expressed in mAh (milliampere-hour). The greater the capacity (mAh), the longer the battery will last before needing to be recharged. Today, research has made it possible to develop rechargeable batteries with a capacity of 800mAh up to 2700mAh for an R6 format. Negative electrode
