Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market
Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.
Quinone flow battery for grid-scale renewables storage now close to commercial viability
Startup Quino Energy has raised more than $7.8 million to scale up its quinone redox flow battery technology. Harvard University and University of Cambridge researchers came up with the initial research for the battery design.
TOPCon solar cell achieves 24.2% efficiency via new plasma-assisted atomic layer deposition tech
A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.
