Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes.
The new generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.
This breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.
With this new technology by NTU, drivers of electric vehicles could save tens of thousands on battery replacement costs and can recharge their cars in just a matter of minutes.
Commonly used in mobile phones, tablets, and in electric vehicles, rechargeable lithium-ion batteries usually last about 500 recharge cycles. This is equivalent to two to three years of typical use, with each cycle taking about two hours for the battery to be fully charged.
In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide.
Titanium dioxide is an abundant, cheap and safe material found in soil. It is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.
Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.
Invented by Associate Professor Chen Xiaodong from NTU’s School of Materials Science and Engineering, the science behind the formation of the new titanium dioxide gel was published in the latest issue of Advanced Materials, a leading international scientific journal in materials science.
Prof Chen and his team will be applying for a Proof-of-Concept grant to build a large-scale battery prototype. With the help of NTUitive, a wholly-owned subsidiary of NTU set up to support NTU start-ups, the patented technology has already attracted interest from the industry.
The technology is currently being licensed by a company for eventual production. Prof Chen expects that the new generation of fast-charging batteries will hit the market in the next two years. It also has the potential to be a key solution in overcoming longstanding power issues related to electro-mobility.
“Electric cars will be able to increase their range dramatically, with just five minutes of charging, which is on par with the time needed to pump petrol for current cars,” added Prof Chen.

Helsinki & Paris, April 15, 2015 - Nokia and Alcatel-Lucent announce today their intention to combine to create an innovation leader in next generation technology and services for an IP connected world. The two companies have entered into a memorandum of understanding under which Nokia will make an offer for all of the equity securities issued by Alcatel-Lucent, through a public exchange offer in France and in the United States, on the basis of 0.55 of a new Nokia share for every Alcatel-Lucent share. The all-share transaction values Alcatel-Lucent at EUR 15.6 billion on a fully diluted basis, corresponding to a fully diluted premium of 34% (equivalent to EUR 4.48 per share), and a premium to shareholders of 28% (equivalent to EUR 4.27 per share) (see Appendix 1), on the unaffected weighted average share price of Alcatel-Lucent for the previous three months. This is based on Nokia's unaffected closing share price of EUR 7.77 on April 13, 2015.
Each company's Board of Directors has approved the terms of the proposed transaction, which is expected to close in the first half of 2016. The proposed transaction is subject to approval by Nokia's shareholders, completion of relevant works council consultations, receipt of regulatory approvals and other customary conditions.
Enabling the connected world
The combined company will be uniquely positioned to create the foundation of seamless connectivity for people and things wherever they are. This foundation is essential for enabling the next wave of technological change, including the Internet of Things and transition to the cloud.
The combined company will have unparalleled innovation capabilities, with Alcatel-Lucent's Bell Labs and Nokia's FutureWorks, as well as Nokia Technologies, which will stay as a separate entity with a clear focus on licensing and the incubation of new technologies.
With more than 40 000 R&D employees and spend of EUR 4.7 billion in R&D in 2014, the combined company will be in a position to accelerate development of future technologies including 5G, IP and software-defined networking, cloud, analytics as well as sensors and imaging.
Alcatel-Lucent and Nokia have highly complementary portfolios and geographies, with particular strength in the United States, China, Europe and Asia-Pacific. They will also bring together the best of fixed and mobile broadband, IP routing, core networks, cloud applications and services. This combination is expected to create access to an expanded addressable market with improved long term growth opportunities.
Consumers are looking to access data, voice and video across networks of all kinds. In this environment technology that used to operate independently now needs to work well together. That is not always the case today, but together Nokia and Alcatel-Lucent are uniquely suited to helping telecom operators, internet players and large enterprises address this challenge.
