Who Really Invented the Rechargeable Lithium-Ion Battery?

Cars That Think

Fifty years after the birth of the rechargeable lithium-ion battery, it’s easy to see its value. Did Exxon invent the rechargeable lithium battery? By Christmas, he had developed a battery with a titanium-disulfide cathode and a liquid electrolyte that used lithium ions. at Oxford.

ANL researchers report photo-excitation can speed up Li-ion charging by factor of two

Green Car Congress

Researchers at the US Department of Energy’s (DOE) Argonne National Laboratory have reported that a new photo-excitation mechanism can speed up the charging of lithium-ion batteries by a factor of two or more. A serious limitation [of lithium-ion batteries], however, is the slow charging rate used to obtain the full capacity.

RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Researchers at Rensselaer Polytechnic Institute have developed a safe, extended cycling lithium-metal electrode for rechargeable Li-ion batteries by entrapping lithium metal within a porous graphene network (Li-PGN). They then looked at the interaction of elemental lithium with such defect sites in the graphene.

Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes

Green Car Congress

A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. At a C/10 rate, the ACP (activated cattail pollen) electrode delivered high specific lithium storage reversible capacities (590 mAh/g at 50 °C and 382 mAh/g at 25 °C) and also exhibited excellent high rate capabilities.

Improving the Charge-Discharge Capacity and Cycleability of Carbon Electrodes for Li-ion Batteries

Green Car Congress

GMP40 (60:40 weight ratio of mixed mesophase pitch carbon and phenolic resin) produced the best results. However, carbon remains the predominant commercial anode material solution at this point. Some studies have demonstrated that carbon coating of graphite improves the anode performance in LIBs. Credit: ACS, Lin et al.

How do sodium-ion batteries charge within seconds – ET Auto

Baua Electric

This abundance makes sodium-ion batteries a potentially cheaper and more sustainable alternative to the lithium-ion batteries that currently dominate the market. However, until now, the performance of sodium-ion batteries has lagged behind that of their lithium-ion counterparts.
