Searching for a better battery

Lithium ion batteries (LIBs) are very popular in portable electronics because of their high energy density and small memory effect. They play an important role in the progress of electric vehicles, power tools, military and aerospace applications.

However, like any other any storage system, LIBs still suffer from many shortcomings. While normal electronic devices have seen very rapid progress following Moore’s law, batteries have advanced only slightly.

Our goal at Nanotech Energy is to minimize that gap by developing a new generation of batteries with performance features far exceeding those currently available in the market.

Generation 1

Graphene super battery

Thanks to its outstanding surface area and high electronic conductivity, Nanotech Energy used graphene to improve the electrochemical properties of the lithium-ion battery anode and cathode simultaneously.

This has enabled a new generation of lithium-ion batteries, we call graphene super battery (Gen I), with outstanding power density, energy density and cycling life.

Highly customizable

Graphene Super-batteries can be customized for high energy or high power applications.

Fast charging

Designed with very low internal resistance, graphene SUPERbatteries have the ability of fast recharging.

Generation 2

Non-flammable Graphene Battery

Lithium ion batteries are widely used in modern electronics and electric cars due to their high energy density and long cycle life.

However, there are increasing safety concerns after reports of the devices catching on fire due to battery failure.

Nanotech Energy is developing a number of non-flammable electrolyte systems with improved safety features while also enhancing the power density of the battery.

Printed circuits

Given its excellent mechanical and electronic properties, graphene is expected to play a critical role in the progress of printed electronics.

Thin, flexible, low-cost and environmentally friendly – this is just a snapshot of what printed electronics can offer.

The rise of this technology can be ascribed to its potential in providing cost-effective solutions to large-area electronic devices at a fraction of the cost of traditional semiconductor technology.

Promising applications

Nanotech Energy’s research and the market for printed electronics is rapidly growing with promising applications in smart packaging, organic solar cells, wearable electronics, and electronic papers.

Flexible electronics

Nanotech Energy has developed a simple, yet effective, method for the direct laser writing of graphene circuits that are flexible, conductive and suitable for the next generation of flexible electronics. Devices of any shapes and structures can be printed within minutes.

$13.6 B

The overall printed electronics market is estimated to reach USD 13.6 billion by 2023 from USD 6.8 billion in 2018.

Graphene supercapacitors

Supercapacitors are attractive energy storage devices with the ability to recharge in seconds rather than hours like traditional lithium-ion batteries.

Supercapacitors are also maintenance free and can be used for up to a million charge/discharge cycles. Their high power density and excellent low temperature performance have made them the technology of choice for back-up power, cold starting, flash cameras, and regenerative braking. They also play an important role in the progress of hybrid and electric vehicles.

However, the low energy density of current supercapacitors is the main impediment to realizing the full commercial potential of this technology.

This has triggered tremendous research efforts on Nanotech Energy’s part in order to develop new electrode materials that are capable of providing a huge amount of energy in a short period of time.
