Компания Terra Supreme внедрила стекловолокно AGY S2 в составные решетки новых свинцово-кислотных батарей

AGY S2 Glass Fiber Reinforces Terra Supreme’s Group 31 Bipolar Batteries High-strength glass fiber enables dimensionally stable composite grids designed to address a primary cause of lead-acid battery failure.

Source | AGY, Terra Supreme AGY’s (Aiken, S.C., U.S.) S2 Glass fiber is being used by Terra Supreme Battery (Albion, Ind., U.S.) in the composite grids incorporated into the company’s new Group 31 bipolar lead-acid batteries. Terra Supreme Battery combines pure lead with high-strength S2 Glass fiber to create dimensionally stable composite grids. The glass fiber reinforcement, reported to be 10X stronger than steel by weight, helps maintain the structural integrity of the battery’s internal grid system throughout repeated charging and discharging cycles. In addition, the reinforced composite-grid technology eliminates positive active-material shedding, which Terra Supreme identifies as a major failure mode across lead-acid battery chemistries. “S2 Glass fiber was developed for applications where high strength, durability and dimensional stability are essential,” says Patrick Hunter, chief commercial officer and president of AGY. “Terra Supreme’s innovative use of S2 Glass demonstrates how advanced glass fiber reinforcement can help transform a well-established battery chemistry and address one of its most persistent performance limitations.” Terra Supreme’s battery uses a bipolar architecture with horizontally oriented plates, an efficient internal current path and no conventional internal busbars. The battery is designed as a direct Group 31 replacement that can operate without changes to an existing charging system. “Our objective was to rethink the lead-acid battery from the inside out,” describes Benny E. Jay, chief technology officer of TSB. “AGY’s S2 Glass fiber provides the strength and dimensional stability required for our composite grids. This enables us to structurally secure the active material, extend service life and deliver significantly improved performance from a familiar, recyclable battery chemistry.” Terra Supreme reports that its Group 31 battery provides 1,200 cold-cranking amps, 1,800 marine-cranking amps 3,000 pulse hot-cranking amps, 240 minutes of reserve capacity and up to 4,000 cycles at 60% depth of discharge. The battery is designed for high-power engine-starting and deep-cycle applications across commercial transportation, emergency services, industrial equipment, agriculture, aerospace, military, marine, recreational vehicle, railroad and off-grid and grid-tied energy-storage markets.
