8 Minimising battery capital costs Challenge: There is widespread industry interest in Li-ion batteries as a replacement for lead-acid, but one drawback of Li-ion technology is its cost. Solution: The latest lead-acid battery technologies, while offering many technical advantages, have a cost factor of 1.4 to 1.6 compared with standard lead-acid types. By contrast, many Li- ion batteries carry a historical cost factor of 4 to 6 over lead-acid.
9 Recycling to reduce costs and environmental damage Challenge: As all batteries have finite operating lifetimes, disposing of them responsibly with minimal environmental impact and cost is always a concern. Solution: Against this background, Li-ion batteries present difficulties. All Li-ion types must be chemically analysed to determine whether they contain any valuable materials. Lithium iron phosphate (LFP) battery recycling is currently hardly worthwhile, while with lithium cobalt oxide (LCO) batteries the cobalt can be recovered and corresponds to about 10 per cent of the
new cell value. However, Li-ion recyclability is anticipated to improve. Lead-acid batteries, however, are easily and virtually completely recyclable.
10 Robust batteries for challenging conditions Challenge: Batteries can be subject to harsh environments, with shock and vibration, wide temperature ranges and heavy-handed treatment from inexperienced operating personnel. Solution: The grain structure of the pure lead used in TPPL batteries makes the plates far less susceptible to corrosion. The batteries are also resistant to harsh shock and vibration conditions, due to their rugged construction and a vibration-resistant compound. They also have a much wider operating temperature range than other lead-acid battery designs. For more information about TPPL technology, please visit:
