Held in Singapore, September 10-13.
After 25 years the Asian Battery Conference finally returns to Singapore. Over these years the conference content and its drivers has of course changed, from a very technical format to one that addresses both the technical and commercial aspects of a growing, developing industry.
If one considers back in 1988 the world lead tonnage consumed was 5.5 million tonne with 65% entering the battery market, today we consume over 11 million tonne with 85% being converted to batteries. It is also facing a declining supply from lead mines, competition for scrap batteries (which has driven prices higher), and the ongoing redistribution of output between China and the rest of the world.
During this period the population of workers within the lead acid battery industry has increased spectacularly, particularly in China where it has increased from around 20 people to 2 million people. Today, China has become the largest lead acid battery manufacturer, exporter and consumer in the world. China and India together produce 50% of the world’s batteries!
Due to the booming market in China and India, the lead acid industry will steadily grow in Asia, continuing to attract large amounts of investment.
Looking at various technical trends in battery manufacturing, and understanding the current market demands, what is the future of the lead–acid batteries in Asia?
1. Punched battery grids technology seems to be imposed, because it has been proven to provide superior performance when compared to grids produced with other technologies.
2. Valve-regulated lead–acid (VRLA) batteries and enhanced flooded lead–acid batteries (EFB) have been developed to allow some recovery of energy by regenerative braking but the dynamic charge-acceptance (DCA) of both these designs will be improved to reach higher levels of recovery. Accordingly, the battery industry has modified absorbent glass mat (AGM) batteries and developed the enhanced flooded battery (EFB) that can accept higher currents and are more robust in deep-discharge service.
