Perth's Talga makes Li-ion battery breakthrough
17 February, 2016Perth-based advanced materials company Talga Resources' preparation of graphite for the Li-ion battery eliminates a number of processing steps otherwise required under conventional graphite refining pathways to meet commercial-level performance in capacity over 100 cycles in a cell test.
Room-temperature lithium metal battery closer to reality?
12 February, 2016Rechargeable lithium metal batteries have been known to offer energy storage capabilities but they are not in common use today because, when recharged, they spontaneously grow treelike bumps called dendrites on the surface of the negative electrode.
New Li-ion battery won't overheat
12 January, 2016A new lithium-ion battery shuts down before overheating, then restarts once it cools down — preventing the kinds of fires that have prompted recalls and bans on a wide range of battery-powered devices.
3D imaging shows how lithium batteries degrade over time
22 December, 2015How disposable lithium batteries degrade during normal use has been tracked in real time by a UCL-led team using sophisticated 3D imaging, giving a new way to non-invasively monitor performance loss and guide the development of more effective commercial battery designs.
Hitachi develops thermally durable solid-state Li-ion battery
15 December, 2015Hitachi, in collaboration with Tohoku University researchers, has developed a technology to reduce the internal resistance of the all-solid-state Li-ion battery using a complex hydride*1 as a solid electrolyte.
Safer batteries for grid-storage and safety-critical applications
01 December, 2015The latest 'water-in-salt' aqueous lithium-ion battery technology could provide power, efficiency and longevity comparable to today's lithium-ion batteries, but without the fire risk, poisonous chemicals and environmental hazards of current lithium batteries.
