Graphene-enhanced batteries - updates
There have been several interesting developments in the field of graphene batteries this month. Here are the main ones:
- GAC to mass produce graphene-enhanced battery for EVs by the end of 2020
- Nanotech Energy concludes $27.5 Million funding round and announces non-flammable battery ready for commercialization
- Stretchable Li-ion battery enhanced with graphene and CNTs to benefit wearable electronics
- KIST researchers develop stretchable graphene-based lithium-ion battery
- Researchers develop a novel graphene-vanadium flexible hybrid battery/supercapacitor
- Talga to supply coated anode products to lithium-ion battery giant Farasis
UK-based startup Payper uses graphene for new pay-at-table technology for restaurants
UK-based start-up Payper Technologies is using graphene to provide the restaurant industry with a new pay-at-table technology.
For this purpose, graphene antennas are printed on paper to enable customers to pay their bill by tapping their smartphone on the receipt. The process is said to take two clicks and under five seconds, without the need to download an app, by using existing Apple Pay or Google Pay.
Honor 10X to sport graphene cooling system
It has been reported that Honor will soon introduce the Honor X10, and that it will feature a graphene-based cooling system.
The phone is expected to be the cheapest 5G model to come from Huawei, so it may get a little warmer than regular smartphones. Thanks to the graphene-based cooling system, the phone will have better heat protection.
Researchers develop new high performance asymmetric supercapacitors
Researchers at Penn State and two universities in China have found that a new kind of supercapacitor, based on manganese oxide with cobalt manganese oxide as a positive electrode and a form of graphene oxide as a negative electrode, could combine the storage capacity of batteries with the high power and fast charging of other supercapacitors.
The group has compared their supercapacitor to others and found that theirs has much higher energy density and power. They believe that by scaling up the lateral dimensions and thickness, their material has the potential to be used in electric vehicles.
So far, they have not tried to scale it up. Instead, their next step will be to tune the interface where the semiconducting and conducting layers meet for even better performance. They want to add the supercapacitor to already developed flexible, wearable electronics and sensors as an energy supply for those devices or directly as self-powered sensors.
The Graphene Flagship has announced 16 New FLAG-ERA projects, that cover a broad range of topics, from fundamental to applied research.
First Graphene (FGR) has entered into a two-year supply agreement with planarTECH to supply materials for the manufacture of personal protective equipment (PPE).
First GrapheneFirst Graphene logo image has announced it is collaborating with Hexcyl to develop PureGRAPH enhanced HDPE materials for use in Hexcyl’s range of oyster baskets and long-line farming systems.
A research team at the Universitat Politècnica de València (URV) used graphene and perovskites to create a nanosensor that detects nitrogen dioxide with 300% improved sensitivity.
Researchers at MIT have previously found a particularly strange pattern in the “twisted” graphene structure, and now they’ve studied it more closely and found that the more layers it has, the better it will work.
A research team has found that adding small amounts of graphene to the production process of carbon fibers both reduces the production cost and strengthens the fibers and so could one day lead to using these materials to improve safety and reduce the cost of producing planes and cars.
