Hala ere, berun-azido bateriaren teknologia hobetzeko tarte esanguratsua dago, azken finean, bere material aktiboen % 25-35 baino ez duelako erabiltzen normalean. Gaur arte, berun-azido 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. Neutroi-izpia 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.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 lead-acid 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.berun-azido baterianeutroien bidezko irudiakin operandoelektrolito deuteratuaerradiografia.lead-acid batteryneutron imagingin operandodeuterated electrolyteradiography.ElektronikaIngeniaritzaKimikaintroduction
