Lead-Acid Batteries

The battery of a motor vehicle is a real powerhouse. It has to deliver very high currents in a short time so that the starter can powerfully crank the engine to start it – and this sometimes at temperatures below 0 °C. Although the basis of the starter battery is generating electricity from lead electrodes in dilute sulphuric acid and has remained unchanged, the requirements have changed significantly. Not only are modern batteries low-maintenance, they must also be capable of reliably starting the engine again and again at short intervals, e.g. in city traffic in start-stop mode. Our fibres reinforce the lead paste on the electrodes so that it sticks to the electrode, does not crack and does not fall off as a result of physical shock. This increases operational reliability and extends the battery service life.
