Manganese X Energy Announces Breakthrough Phase 2 Battery Test Results with 70% Capacity Retention After 4,600 Cycles and Advances to Phase 3 Testing with U.S. Battery Innovator C4V
Manganese X Energy (OTCQB: MNXXF) has achieved breakthrough results in Phase 2 battery testing with U.S. battery innovator C4V, demonstrating 70% capacity retention after 4,600 cycles - more than double the cycle life of conventional NMC-based EV batteries.
The company's high-purity battery-grade manganese, sourced from its Battery Hill project in New Brunswick, has outperformed both Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) chemistries. Each test cycle included a 60-minute charge, 60-minute discharge, and 5-minute rest period.
Following these exceptional results, Manganese X is advancing to Phase 3 testing, which will evaluate the material in multilayer pouch cells (3Ah design) to meet end-user product requirements. Success could lead to a potential binding offtake deal with C4V.
Manganese X Energy (OTCQB: MNXXF) ha ottenuto risultati importanti nei test di Fase 2 sulle batterie con l'innovatore statunitense C4V, dimostrando una ritenzione di capacità del 70% dopo 4.600 cicli - più del doppio della durata ciclica delle tradizionali batterie EV a base NMC.
Il manganese ad alta purezza e grado batteria dell'azienda, proveniente dal progetto Battery Hill nel New Brunswick, ha superato sia le chimiche LFP (Lithium Iron Phosphate) sia LMFP (Lithium Manganese Iron Phosphate). Ogni ciclo di prova prevedeva una carica di 60 minuti, una scarica di 60 minuti e una pausa di 5 minuti.
A fronte di questi risultati eccezionali, Manganese X passa alla Fase 3 dei test, che valuterà il materiale in celle pouch multilivello (design da 3Ah) per rispondere ai requisiti dei prodotti finali. Il successo potrebbe portare a un potenziale accordo di offtake vincolante con C4V.
Manganese X Energy (OTCQB: MNXXF) ha alcanzado resultados destacados en las pruebas de fase 2 con el innovador estadounidense C4V, demostrando una retención de capacidad del 70% tras 4.600 ciclos, más del doble de la vida útil en ciclos de las baterías EV convencionales basadas en NMC.
El manganeso de alta pureza y calidad para baterías de la compañía, procedente de su proyecto Battery Hill en New Brunswick, ha superado tanto a las químicas LFP (fosfato de hierro y litio) como LMFP (fosfato de litio-manganeso-hierro). Cada ciclo de prueba incluyó 60 minutos de carga, 60 minutos de descarga y 5 minutos de reposo.
Tras estos excepcionales resultados, Manganese X avanza a la fase 3 de pruebas, que evaluará el material en celdas pouch multicapa (diseño de 3Ah) para cumplir los requisitos de producto final. El éxito podría conducir a un posible acuerdo de offtake vinculante con C4V.
Manganese X Energy (OTCQB: MNXXF)는 미국 배터리 혁신 기업 C4V와의 2상 배터리 테스트에서 획기적인 성과를 달성하여 4,600회 사이클 후 70%의 용량 유지를 입증했습니다. 이는 기존의 NMC 기반 전기차 배터리 수명보다 2배 이상 긴 수명입니다.
회사의 고순도 배터리 등급 망간은 뉴브런즈윅의 Battery Hill 프로젝트에서 공급되며, LFP(리튬 인산철)와 LMFP(리튬 망간 철 인산염) 계열보다 우수한 성능을 보였습니다. 각 테스트 사이클은 60분 충전, 60분 방전, 5분 휴식을 포함했습니다.
이러한 탁월한 결과에 따라 Manganese X는 3상 시험으로 진행하여 다층 파우치셀(3Ah 설계)에서 재료를 평가해 최종 제품 요구사항을 충족할 예정입니다. 성공 시 C4V와의 잠재적 구속성 오프테이크 계약으로 이어질 수 있습니다.
Manganese X Energy (OTCQB: MNXXF) a obtenu des résultats majeurs lors des essais de phase 2 avec l'innovateur américain C4V, démontrant une rétention de capacité de 70 % après 4 600 cycles — plus du double de la durée de vie cyclique des batteries VE traditionnelles à base de NMC.
Le manganèse de haute pureté et de qualité batterie de la société, provenant de son projet Battery Hill au Nouveau-Brunswick, a surpassé les chimies LFP (phosphate de fer et de lithium) et LMFP (phosphate de lithium-manganèse-fer). Chaque cycle d'essai comprenait 60 minutes de charge, 60 minutes de décharge et 5 minutes de repos.
À la suite de ces résultats remarquables, Manganese X passe à la phase 3 des tests, qui évaluera le matériau dans des cellules pouch multicouches (conception 3Ah) pour répondre aux exigences des produits finaux. Le succès pourrait déboucher sur un accord d'offtake contraignant potentiel avec C4V.
Manganese X Energy (OTCQB: MNXXF) hat in Phase-2-Batterietests mit dem US-Batterie-Innovator C4V bahnbrechende Ergebnisse erzielt und eine Kapazitätserhaltung von 70% nach 4.600 Zyklen nachgewiesen – mehr als das Doppelte der Zyklenfestigkeit herkömmlicher NMC-basierter EV-Batterien.
Das hochreine, batteriegeeignete Mangan des Unternehmens, gewonnen aus dem Battery Hill-Projekt in New Brunswick, übertraf sowohl LFP- (Lithium-Eisenphosphat) als auch LMFP-Chemien (Lithium-Mangan-Eisen-Phosphat). Jeder Testzyklus umfasste 60 Minuten Laden, 60 Minuten Entladen und 5 Minuten Ruhezeit.
Aufgrund dieser außergewöhnlichen Ergebnisse geht Manganese X nun in die Phase-3-Tests, in denen das Material in mehrlagigen Pouch-Zellen (3Ah-Design) bewertet werden soll, um den Anforderungen der Endprodukte zu genügen. Ein Erfolg könnte zu einem potenziellen verbindlichen Abnahmevertrag mit C4V führen.
