[{"type":"text","content":"\n\n17 April 2025\nGelion plc (\"Gelion\", the \"Company\" or the \"Group\")\nGelion Achieves Breakthrough in Sulfur Battery Coin Cell Results\nTerms Agreed on a Materials Testing Agreement (MTA) with a Tier-One Battery Manufacturer\nGelion plc (AIM: GELN), the global energy storage innovator, announces significant advancements in its Sulfur battery technology, achieving exceptional performance in high power and in cycling characteristics that supports its goals toward compelling commercial market propositions for drones, transportation, and grid and remote energy storage systems. Building upon its recent collaboration with the Max Planck Institute of Colloids and Interfaces (MPI), announced in March 2025, Gelion has successfully integrated MPI's technology into sodium-sulfur coin cells, the industry standard battery testing platform.\nInitial tests have yielded exceptional results:\n· Superior Power Capability: Maintaining robust capacity retention even under extreme charge / discharge rates, with six-minute charge and six-minute discharge cycles.\n· Outstanding Longevity: Evidence to support MPI testing which achieved over 1,000 charge/discharge cycles with industry-standard capacity retention under one-hour charge and one-hour discharge cycles.\n· Industrially relevant results: These tests represent a progression from laboratory material testing conditions to the industrially relevant coin cell development platform*.\n*The transition from coin cells to larger format commercial cells is a well-established pathway. In this case, it is underpinned by the combined technology introduced by MPI and Gelion and will involve adapting this technology to standard large-format cell parameters and componentry.\nAdvancements in Sulfur Battery Performance: Historically, the commercial adoption of sulfur batteries has been constrained by two key challenges: short cycle life, which has limited their potential use to niche markets, and low power output, making them unsuitable for applications in transportation and aerial drones.\nGelion's test results address these prior challenges, paving the way for sulfur battery products to achieve a compelling product-market fit and route to commercial adoption.\n...
