MIT engineers have developed electrodes to avoid the stresses that cause component fracturing in solid-state batteries.

Solid-state batteries need a mechanism that allows for expansion and contraction during charge/discharge cycles, without changing the electrode's outer dimensions.

A new electrode concept from the laboratory of Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and Professor of Materials Science and Engineering could meet that need.

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.
