    Lead-acid batteries have consistently accounted for the largest market share of secondary batteries. However, there is still significant opportunity for improvement of lead-acid battery technology. Typically, lead-acid batteries do not make use of more than 25-35 % of their active materials. To date, there have been few reports of techniques for monitoring of the internal processes which occur during operation of lead-acid batteries. Neutron imaging presents a novel technique for in operando monitoring of lead-acid batteries; however, it requires an appropriately designed leadacid battery. The neutron beam has to pass through the battery without attenuation, carrying information about the inner components. In this work we have designed, optimized and validated a neutron-friendly lead-acid battery, using deuterated electrolyte and a neutron transparent casing.

    Gaurko egunean, berun-azido bateriek mantentzen dute bateria sekundarioen merkatu-kuotarik handiena oraindik ere. Hala ere, berun-azido bateriaren teknologia hobetzeko tarte esanguratsua dago, azken finean, bere material aktiboen % 25-35 baino ez duelako erabiltzen normalean. Gaur arte, berunazido baterien barne-fenomenoak monitorizatzeko tekniken inguruko ikerketa-lan gutxi dago.

    Neutroiak erabiltzen dituzten teknikak egokiak izan daitezke berun-azido bateria in operando monitorizatzeko. Horretarako, espresuki diseinaturiko berun-azido bateria beharrezkoa da. Neutroiizpia ahultzerik gabe pasatu behar da baterian zehar, barne-elementuetako informazioa azaleratuz. Lan honetan horrelako bateria diseinatu, optimizatu eta egiaztatu dugu, elektrolito deuteratua eta neutroiekiko gardena den karkasa erabiliz.
