近日,来自厦门大学的白华教授,在国际知名期刊Journal of Materials Chemistry A上发表题为“Low-cost p-benzoquinone-formaldehyde polymer/reduced graphene oxide composite films as a cathode material for rechargeable lithium-ion batteries”的观点文章。该观点文章设计并合成了一种对苯醌-甲醛聚合物,并且与还原氧化石...
The performance of lithium-ion battery is highly dependent on its interfacial chemistry, which is regulated by electrolytes. Conventional electrolyte typically contains polar solvents to dissociate Li salts. Here, we report a novel weakly-solvating electrolyte (WSE) that consists of a pure non-polar...
Lithium-ion batteries have aided the portable electronics revolution for nearly three decades. They are now enabling vehicle electrification and beginning to enter the utility industry. The emergence and dominance of lithium-ion batteries are due to their higher energy density compared to other rechargea...
Can Chemistry Offer a Better Lithium Ion Battery?Umair IrfanClimateWire
Currently, lithium-ion batteries enjoy prevalence in fields like automotive, consumer electronics and renewable energy because of their merits of high energy density, long cycle life, and low self-discharge rate. However, such types of batteries also come with their own set of challenges in terms...
Lithium-ion batteries have transformed society because they are lightweight and rechargeable. They have therefore become ubiquitous in everything from mobile phones, tablets and laptops to electric cars. They could also, in the future, become important in storing the intermittently available energy prod...
Lithium-ion batteries are very popular for energy storage - learn about the several different variations of lithium-ion chemistry.
Binary metal oxides are attractive anode materials for lithium-ion batteries. Despite sustained effort into nanomaterials synthesis and understanding the initial discharge mechanism, the fundamental chemistry underpinning the charge and subsequent cycles—thus the reversible capacity—remains poorly understood. ...
"We went with zinc-manganese because for devices worn next to the skin,it's a safer chemistry than lithium-ion batteries,which can produce deadly compounds when they break," says Nguyen. The resulting battery is flexible and can be stretched to twice its normal length,has a s...
On the environmental competitiveness of sodium-ion batteries under a full life cycle perspective – a cell-chemistry specific modelling approach Sodium-ion batteries (SIB) are among the most promising type of post-lithium batteries, being promoted for environmental friendliness and the avoidance of .....
