New group of materials could lead to faster-charging Li-ion batteries

Green Car Congress

The researchers, led by Professor Clare Grey, found that lithium ions move through the materials at rates that far exceed those of typical electrode materials, which equates to a much faster-charging battery. The maximum power output and minimum charging time of a lithium-ion battery depend on both ionic and electronic transport.

PsiQuantum, Mercedes-Benz R&D: fault-tolerant quantum computing can accelerate battery designs

Green Car Congress

Lithium-ion batteries function during charge and discharge cycles by moving charge from one electrode to another across an electrolyte material. Development of new Li-ion batteries currently involves a significant amount of trial and error. Research 4, 023019 doi: 10.1103/PhysRevResearch.4.023019. 4.023019.

DRX Consortium to accelerate commercialization of disordered rock salt (DRX) cathode materials

Green Car Congress

DRX cathodes could provide batteries with higher energy density than conventional lithium-ion battery cathodes made of nickel and cobalt, two metals that are in critically short supply. In a rock salt structure, cations (positively charged ions) and anions (negatively charged ions) are arranged in a specific pattern.

CMU study suggests difficulties in reaching targeted low price points for Li-ion batteries

Green Car Congress

Their findings suggest that prismatic cells, which are able to further capitalize on the cost reduction from larger formats, can offer further reductions than those possible for cylindrical cells.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Crucial to the idea of lowering the cost of battery materials, myo-inositol is an abundant organic compound familiar to industry.
