SJTU team develops self-healing binder for silicon microparticle anodes

Green Car Congress

Researchers at Shanghai Jiao Tong University (SJTU) have developed a polymer binder—PAA-P(HEA-co-DMA)—for use with silicon microparticle (SiMP) anodes. Thus, the cycle stability and rate performance are remarkably improved under high reversible capacity or electrode loading.

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A team at Stanford University has developed stable silicon Li-ion battery anodes by incorporating a conducting polymer hydrogel into the Si-based material. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si.

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 ).
