description	Graphite particles comprises natural veined graphite or flake graphite particle clusters with specified average diameter, specific surface and apparent density values. Graphite particles comprise natural veined graphite or flake graphite particle clusters having a D50 diameter of 8-22 Micro as measured by laser beam diffraction, a specific surface of 2.5-6 m2>/g as measured by nitrogen gas adsorption and an apparent density of >= 0.25 g/cm3> before compaction and >= 0.55 g/cm3> after compaction, the apparent density after compaction being 1.8-2.5 times that before compaction. Graphite particles comprises natural veined graphite or flake graphite particle clusters with specified average diameter, specific surface and apparent density values. Graphite particles comprise natural veined graphite or flake graphite particle clusters having a D50 diameter of 8-22 microns as measured by laser beam diffraction, a specific surface of 2.5-6 m /g as measured by nitrogen gas adsorption and an apparent density of \- 0.25 g/cm before compaction and \- 0.55 g/cm after compaction, the apparent density after compaction being 1.8-2.5 times that before compaction. Es werden Graphitteilchen bereitgestellt, die für die Herstellung einer negativen Elektrode einer nicht-wäßrigen Sammelbatterie zu dem Zweck eingesetzt werden, um die Eigenschaften zum raschen Laden/Entladen und die Eigenschaften hinsichtlich der Zykluslebensdauer zu verbessern und die irreversible Kapazität im ersten Zyklus zu verringern, wobei die Graphitteilchen klumpige Graphitteilchen sind, die aus natürlichen gemaserten Graphitteilchen oder Flockengraphitteilchen gebildet und dadurch gekennzeichnet sind, daß der Teilchendurchmesser mit einer Wahrscheinlichkeit von 50% (D50-Durchmesser), die spezifische Oberfläche und die apparente Dichte dieser Teilchen auf jeweils spezifische Bereiche eingeschränkt sind.
