24M hails semi-solid technology ‘milestone’

Mon, 03/04/2019 - 00:00 -- John Shepherd

US-based 24M has reached a “significant milestone” towards scaling up development of its novel semi-solid lithium-ion technology.

The Massachusetts company said it has developed and delivered “commercially viable, high energy density lithium-ion cells with energy densities exceeding 250 watt-hours per kilogram (Wh/kg)”.

The development of the high energy density nickel manganese cobalt (NMC) cells is part of a US$7 million three-year contract awarded to 24M in 2016 by the United States Advanced Battery Consortium (USABC), in cooperation with the US Department of Energy.

The Department of Energy (DoE) marked ‘National Battery Day’ in the US with the launch of the country’s first lithium-ion battery recycling centre.

The ‘ReCell Center’ has been set up at the Argonne National Laboratory to “help the United States grow a globally competitive recycling industry and reduce [its] reliance on foreign sources of battery materials”, the DoE said.

Lithium-ion batteries in the US are currently collected and recycled at a rate of less than 5%. The DoE aims to eventually “profitably capture 90% of all lithium based battery technologies”, and subsequently “recover 90% of the key materials” from lithium batteries.

US-Korean partnership for novel lithium technologies

Mon, 02/25/2019 - 00:00 -- Hugh Finzel

PolyPlus and SK Innovation are to jointly develop “the first rechargeable lithium metal battery with a conductive glass separator”.

The partners’ initial goal will be to produce and test prototype cells using California-based PolyPlus’ solid-state lithium anode laminate, which is describe as having “the potential to double the energy density and cycle life of rechargeable batteries”.

Under the agreement, financial terms of which have note been disclosed, South Korea’s SK Innovation will provide development funding, and will receive an option to make “a significant investment in Polypus” and an option to negotiate a licence to PolyPlus technology for use in electric vehicles.

US Energy Secretary Rick Perry

The US Department of Energy (DoE) has launched a Lithium-ion Battery Recycling Prize and an associated Battery Recycling R&D Centre, in a bid to reduce “America’s dependence on foreign sources of critical (battery) materials”.

The recycling prize will make awards totalling US$5.5 million to encourage innovation from American entrepreneurs in the fields of collecting, storing, and transporting discarded lithium-ion batteries for eventual recycling.

In addition, the US will invest $15m to establish the recycling centre “focused on cost-effective recycling processes to recover lithium battery materials”. The centre is to be led by Argonne National Laboratory, with the National Renewable Energy Laboratory and Oak Ridge National Laboratory.

EcoHouse in MUST EcoVillage

Missouri University of Science and Technology (MUST) has installed two new advanced lead battery microgrid systems at its campus EcoVillage, to test advancements in lead battery energy storage for use as a renewable resource in communities of the future.

The microgrids will supply two student-occupied homes in the EcoVillage— a ‘living laboratory’ of homes designed and created by Must students who competed in the US Department of Energy’s biennial Solar Decathlon—with stored electricity from the systems, which run off charging algorithms from a 24-hour, cloud-based control system.
