Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major causes for the drop in capacity over time in Li-ion batteries is the degradation of the widely used graphite anodes. One of the major challenges for graphite anodes is the exfoliation of the graphite framework on deep cycling at a fast current rate. 0c02742.

Graphene oxide-sulfur (GO-S) nanocomposite cathodes for high-capacity, stable cycling lithium sulfur batteries

Green Car Congress

A team from Lawrence Berkeley National Laboratory and Tsinghua University (China) have synthesized graphene oxide-sulfur (GO-S) nanocomposite cathodes and applied them in lithium/sulfur cells to show a high reversible capacity of 950-1400 mAh g -1 and stable cycling for more than 50 deep cycles at 0.1C (1C = 1675 mA g -1 ).

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

Compared to advanced lead-acid batteries, the PbC batteries: Support higher [10-20x] charge acceptance and faster recharge [5-10x] in partial state-of-charge (PSOC) applications; Offer an 4x increase in cycle life in 100% depth-of-discharge applications; and. This limits the ability of battery to take on recharge.
