RETRANSMISSION: 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, 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. Successful Phase 3 results could lead to commercial adoption and potential binding offtake agreements with C4V.
Manganese X Energy (OTCQB:MNXXF) ha ottenuto risultati rivoluzionari nella Phase 2 dei test sulle batterie con l'innovatrice statunitense C4V, dimostrando una rimanenza di capacità del 70% dopo 4.600 cicli - oltre il doppio della durata ciclica delle batterie EV tradizionali a base di NMC.
Il manganese ad alta purezza e qualità batteria dell'azienda, proveniente dal progetto Battery Hill in New Brunswick, ha superato sia le chimiche Lithium Iron Phosphate (LFP) sia Lithium Manganese Iron Phosphate (LMFP). Ogni ciclo di prova prevedeva una carica di 60 minuti, una scarica di 60 minuti e una pausa di 5 minuti.
In seguito a questi risultati eccezionali, Manganese X passerà alla Phase 3 dei test, che verificherà il materiale in celle pouch multilayer (design da 3Ah) per soddisfare i requisiti dei prodotti finali. Esiti positivi della Phase 3 potrebbero aprire la strada all'adozione commerciale e a potenziali accordi di offtake vincolanti con C4V.

Un éxito en la Fase 3 podría conducir a la adopción comercial y a posibles acuerdos vinculantes de offtake con C4V.
Manganese X Energy (OTCQB:MNXXF)는 미국 배터리 혁신기업 C4V와 함께한 2단계(Phase 2) 배터리 테스트에서 획기적인 성과를 냈습니다. 4,600회 사이클 후에도 70%의 용량을 유지하며 기존 NMC 기반 전기차 배터리보다 사이클 수명이 두 배 이상 길게 나타났습니다.
뉴브런즈윅의 Battery Hill 프로젝트에서 나온 고순도 배터리 등급 망간은 리튬 인산철(LFP) 및 리튬 망간 인산철(LMFP) 계열보다 우수한 성능을 보였습니다. 각 테스트 사이클은 60분 충전, 60분 방전, 5분 휴식으로 진행되었습니다.
이러한 탁월한 결과를 바탕으로 Manganese X는 Phase 3 테스트로 진입하여 멀티레이어 파우치 셀(3Ah 설계)에서 재료를 평가해 최종 사용자 제품 요구사항을 충족할 예정입니다. Phase 3가 성공하면 상업적 채택 및 C4V와의 구속력 있는 오프테이크 계약 체결로 이어질 수 있습니다.
Manganese X Energy (OTCQB:MNXXF) a obtenu des résultats majeurs lors des tests de batterie de la Phase 2 avec l'innovateur américain C4V, démontrant une rétention de capacité de 70% après 4 600 cycles — soit plus du double de la durée de vie cyclique des batteries VE classiques à base de NMC.
Le manganèse de haute pureté et qualité batterie de la société, issu de son projet Battery Hill au New Brunswick, a surpassé les chimies Lithium Iron Phosphate (LFP) et Lithium Manganese Iron Phosphate (LMFP). Chaque cycle de test comprenait 60 minutes de charge, 60 minutes de décharge et 5 minutes de repos.
Suite à ces résultats exceptionnels, Manganese X passe à la Phase 3 des tests, qui évaluera le matériau dans des cellules pouch multicouches (design 3Ah) afin de répondre aux exigences des produits finaux. Des résultats positifs en Phase 3 pourraient mener à une adoption commerciale et à d'éventuels accords d'offtake contraignants avec C4V.
Manganese X Energy (OTCQB:MNXXF) hat in Phase‑2-Batterietests mit dem US‑Innovator C4V bahnbrechende Ergebnisse erzielt und zeigt eine Kapazitätserhaltung von 70% nach 4.600 Zyklen – mehr als das Doppelte der Zyklusfestigkeit herkömmlicher NMC‑basierter EV‑Batterien.
Das hochreine, batteriegeeignete Mangan des Unternehmens aus dem Projekt Battery Hill in New Brunswick übertraf sowohl Lithium‑Eisenphosphat (LFP) als auch Lithium‑Mangan‑Eisenphosphat (LMFP) Chemien. Jeder Testzyklus umfasste 60 Minuten Laden, 60 Minuten Entladen und eine 5‑minütige Ruhephase.
Aufgrund dieser herausragenden Resultate geht Manganese X in die Phase 3, in der das Material in mehrlagigen Pouch‑Zellen (3Ah‑Design) geprüft wird, um die Anforderungen von Endprodukten zu erfüllen. Erfolgreiche Phase‑3‑Ergebnisse könnten zur kommerziellen Einführung und zu potenziellen verbindlichen Abnahmevereinbarungen mit C4V führen.
