Overview
FIAMM is an Italian industrial brand whose name originated from Fabbrica Italiana Accumulatori Motocarri Montecchio. The company began in 1942 with a focus on electric-traction batteries and starter batteries for vehicles. Over time, it developed from an Italian accumulator producer into a supplier serving automotive manufacturers, industrial operators, distributors, and replacement markets in several countries. Its principal technical heritage is in lead-acid battery technology, covering batteries for vehicle starting applications as well as stationary and industrial uses. The business has also been associated with acoustic equipment, including horns and warning devices. FIAMM’s early development was closely linked to Italian transport and vehicle manufacturing. In 1950, the company displayed its products at motor shows alongside major automobile manufacturers, and a FIAMM battery was fitted to the Ferrari that won that year’s Mille Miglia. The company subsequently obtained an original-equipment supply relationship with Innocenti for the Lambretta scooter. During the 1970s, FIAMM expanded its original-equipment role and became a supplier to important European car manufacturers. Its industrial battery business also served major Italian operators, including SIP and Enel, indicating that the brand’s activities extended beyond automotive replacement products into infrastructure and stationary-power applications. Internationalization became more visible during the 1980s. FIAMM exported stationary batteries to the United States and established operations in two major European markets through FIAMM Germany and FIAMM France. The company also maintained a public presence through participation in motorsport and other sporting activities, including rallying, Formula 1, Formula Indy, the Paris-Dakar event, and offshore racing. In the 1990s, FIAMM introduced a new generation of professional management. During the 2000s, it opened plants outside Italy, acquired several battery distributors in Europe, and invested in battery technology and production capabilities. The modern FIAMM battery business was created through a separation from the wider FIAMM Group. The automotive-battery and industrial-battery activities based on lead-acid technology were organized as FIAMM Energy Technology. A strategic partnership with Hitachi Chemical was agreed in 2016, and FIAMM Energy Technology was formed in February 2017. Hitachi Chemical took a 51 percent stake, while the FIAMM Group retained 49 percent. The transaction involved an €86 million operation, comprising €52 million paid by Hitachi and a further €34 million capital increase. In 2020, Showa Denko acquired all of Hitachi Chemical’s shares; Hitachi Chemical subsequently changed its name to Showa Denko Materials Co. FIAMM therefore became part of the Japanese industrial-materials group while retaining its Italian industrial identity and battery-focused activities.
History
FIAMM was established in Italy in 1942 under the name Fabbrica Italiana Accumulatori Motocarri Montecchio. Its initial production centered on batteries for electric traction and vehicle starting. The company’s early commercial development took place alongside the expansion of Italian vehicle manufacturing. In 1950, FIAMM exhibited at motor shows with leading automobile manufacturers, and a FIAMM battery was installed in the Ferrari that won the Mille Miglia that year. Its first original-equipment supply relationship with a major brand was for Innocenti’s Lambretta scooter. During the 1970s, FIAMM became an original-equipment supplier to important European automobile manufacturers. In parallel, its stationary-battery business supplied large Italian operators, including SIP and Enel. The company expanded internationally in the following decade: it exported stationary batteries to the United States and entered Germany and France through dedicated FIAMM operations. Its sporting visibility also broadened through involvement in rallying, Formula 1, Formula Indy, Paris-Dakar, and offshore racing. In the 1990s, FIAMM appointed a new generation of professional managers. The 2000s brought further international development, including overseas plant openings, acquisitions of European battery distributors, and investment in technology. The wider FIAMM Group also explored activities beyond its core battery operations, while the automotive and industrial lead-acid divisions continued to form the basis of the battery business. The battery activities were subsequently separated from the wider FIAMM Group and organized as FIAMM Energy Technology. In November 2016, FIAMM and Hitachi Chemical signed an agreement to create an Italian-Japanese joint venture. FIAMM Energy Technology was established in February 2017, with Hitachi Chemical holding 51 percent and the FIAMM Group retaining 49 percent. The operation was valued at €86 million, consisting of a €52 million payment by Hitachi and a €34 million capital increase. Misao Nakagawa became president and Yasuhiko Nakayama became chief executive officer. In 2020, Showa Denko acquired 100 percent of Hitachi Chemical’s shares. Hitachi Chemical changed its name to Showa Denko Materials Co. from October 1, 2020. FIAMM Energy Technology consequently became part of the Showa Denko corporate group, while continuing its Italian battery-industry identity.
