Battery revolution upon us

Published

on

Although the evolution of the lithium-ion battery has been slow in the past few years, there are some new opportunities and potential markets in the industry for companies to take advantage of, writes DR XIAOXI HE, Technology Analyst, IDTechEx.

Many interests have been raised within the battery business in 2015 through a number of activities: the launch of Tesla’s Powerwall with low prices supported by the capability of Gigafactory, Apple’s patent relating to charging and managing power in a device with solid-state batteries, LG Chem’s opening of a mega battery plant in Nanjing, Bosch’s purchase of polymer solid-state battery company Seeo, etc. Not to mention the tremendous number of investment, acquisitions, partnerships and joint ventures.

At the same time, new battery technologies are appearing continuously with descriptions like “doubled performance”, “charged in a few minutes”, “cost reduction of more than 70%”, making the public even more confused about the real breakthroughs. However, one can provide a clear perspective of emerging technologies, new opportunities and potential markets in the battery industry.

Opportunities can be found from different dimensions

Since the first introduction by Sony in the 1990s, lithium-ion batteries have become one of the most familiar and common battery technologies in our life. The involving technologies are relatively mature and the facilities are in place. With the expansion of existing manufacturing plants by battery giants such as Samsung SDI, LG Chem and Panasonic, economy of scale will be further achieved. However, with so many advantages, the improvement of lithium-ion batteries is slow compared with other electronic components, both in terms of performance and cost reduction. The liquid electrolyte used in the traditional lithium-ion batteries may cause serious safety concerns. On the other hand, with the development of wearable devices, printed electronics, Internet of Things (IoT), robotics and electric vehicles, batteries with more features, more powerful performances and lower costs are required. Those factors have motivated players to find bigger opportunities.

Therefore, the battery industry is explored based on a number of different dimensions. Interests have been aroused in:

      Thin-film batteries (based on thickness)

      Micro-batteries and large-area batteries (based on size)

      Flexible batteries (based on mechanical properties)

      Special-shape batteries (based on form factors)

      Printed batteries (based on manufacturing methods)

      Solid-state, lithium anode, silicon anode batteries (based on technologies)

      Energy storage system (ESS) and electric vehicle (EV) applications (based on applications)

All the areas listed above indicate new opportunities. Those areas may be influenced by each other and may have some overlap. For instance, batteries with better technologies may be used in ESS and EV applications, providing better safety and better performance. A thin-film battery is also flexible, and can be made by printing, or based on all solid-state components, or be very small. Market growth of these areas is affected by the costs. Except the last one (ESS and EV applications), the others are also limited significantly by technology maturity. The IDTechEx Research report “Flexible, Printed and Thin Film Batteries 2016-2026: Technologies, Markets, Players” focuses on the first 4 areas as well as solid-state batteries with these features.

Further cost reduction may not rely on technology improvement

Battery technology improvement is based on electrochemical restriction and it is difficult to have sudden significant breakthroughs. In addition, a practical battery is a combination of many considerations including, but not limited to, energy density, power density, lifetime, safety and cost. Many press releases may emphasis one or several improvements but avoid talking about the others. Most existing commercial batteries are already based on relatively mature, proven technologies, but some of them are not well-known. Examples include thin-film solid-state batteries and printed batteries. As the battery development is a long and difficult process, future battery cost reduction are mainly rely on economy of scale, little on technology improvement.

Regulations and policies play a significant role in large deployment

In May 2013 the German market incentive program for battery storage systems was introduced which changed the residential battery installation structure immediately, with 2,700 installations to enjoy the incentives in 2013, jumping to 13,100 by 2015. Also, China’s decision to remove subsidies for nickel manganese cobalt (NMC) batteries for electric buses also crucially influenced this industry. It indicated that for ESS or EV applications, self-sustainability has not been fully achieved and therefore policy changes can affect them greatly.

Batteries with new technologies will be tried in small gadgets first

Large devices or systems generally require high reliability and safety. Therefore, new battery technologies will tend not to be applied in them initially or in short-term period. Toyota, for example said in January of 2014 that it was working on solid-state battery technologies for cars, but the firm did not expect to have a product within a decade.

Apple also paid lots of attention in solid-state batteries, but it is focusing on portable electronics /wearables /MEMs applications. As early as 2013, the US Patent & Trademark Office already published a patent application from Apple that revealed charging techniques for solid-state batteries. In early 2014, Apple bought all the patents from Infinite Power Solutions after it stopped trading, a company previous working on solid-state thin-film batteries. In November 2015, Apple published another patent related to thin-film solid-state batteries.

In solid-state lithium ion batteries, both the electrodes and the electrolyte are solid-state. Solid-state electrolyte normally behaves as the separator as well. It is safer, especially for those with inorganic solid electrolyte (all organic electrolytes are flammable, no matter whether solid or liquid). Solid-state electrolytes allow scaling due to the elimination of certain components (e.g. separator and casing). Therefore, they can potentially be made with a higher energy density. In addition, they are more resistant to changes in temperature and physical damages occurred during usage. Therefore they can handle more charge/discharge cycles before degradation, promising a longer life time. Due to the flexibility of the casing and without the limitation of liquid electrolyte, solid-state batteries can be made into different form factors, sizes and shapes.

However, the ionic conductivities of solid-state batteries at room temperatures are generally low. In addition, they usually have high internal resistance due to the unstable solid electrolyte interface (SEI). Most solid-state batteries suffer from low C-rate and may not be able work at room temperature. Examples include 3000 taxis in France with solid-state batteries working at elevated temperatures. Also, solid-state batteries are much more expensive. The current low C-rate, low power makes them suitable to be applied in small devices earlier.

Thinness, flexibility and printed possibility will be the most addressed features

As new battery technologies will be applied in small electronic gadgets first, new features beyond traditional capabilities such as thinness, flexibility and printed Possibility will be addressed. According to IDTechEx Research in the report “Flexible, Printed and Thin Film Batteries 2016-2026: Technologies, Markets, Players”, there are other technologies that can make thin, flexible and printed batteries besides solid-state batteries, such as printed carbon zinc batteries and thin lithium-ion pouch batteries.

The total market of thin, flexible and printed batteries will reach $471 million by 2026. Most of those batteries are for small or mediate power devices and focus on form factor, thickness, size and manufacturing aspects, but they share technologies that can be used for other applications. Similar to the development roadmap of traditional lithium-ion batteries from consumer electronics to EV and ESS, batteries with new technologies may target consumer electronics as the initial entry. Even bigger opportunities for new technologies will come after approval in these applications.

For traditional battery technologies, demand is further created in the EV and ESS sectors as the growth in consumer electronics is approaching a plateau. Cost reduction is the key.

How we use phones to avoid human contact

A recent study by Kaspersky Lab has found that 75% of people pick up their connected device to avoid conversing with another human being.

Published

Connected devices are becoming essential to keeping people in contact with each other, but for many they are also a much-needed comfort blanket in a variety of social situations when they do not want to interact with others. A recent survey from Kaspersky Lab has confirmed this trend in behaviour after three-quarters of people (75%) admitted they use a device to pretend to be busy when they don’t want to talk to someone else, showing the importance of keeping connected devices protected under all circumstances. 

Imagine you’ve arrived at a bar and you’re waiting for your date. The bar is busy, and people are chatting all around you. What do you do now? Strike up a conversation with someone you don’t know? Grab your phone from your pocket or handbag until your date arrives to keep yourself busy? Why talk to humans or even make eye-contact with someone else when you can stare at your connected device instead?

The truth is, our use of devices is making it much easier to avoid small talk or even be polite to those around us, and new Kaspersky Lab research has found that 72% of people use one when they do not know what to do in a social situation. They are also the ‘go-to’ distraction for people even when they aren’t trying to look busy or avoid someone’s eye. 46% of people admit to using a device just to kill time every day and 44% use it as a daily distraction.

In addition to just being a distraction, devices are also a lifeline to those who would rather not talk directly to another person in day-to-day situations, to complete essential tasks. In fact, nearly a third (31%) of people would prefer to carry out tasks such as ordering a taxi or finding directions to where they need to go via a website and an app, because they find it an easier experience than speaking with another person.

Whether they are helping us avoid direct contact or filling a void in our daily lives, our constant reliance on devices has become a cause for panic when they become unusable. A third (34%) of people worry that they will not be able to entertain themselves if they cannot access a connected device. 12% are even concerned that they won’t be able to pretend to be busy if their device is out of action.

Dmitry Aleshin, VP for Product Marketing, Kaspersky Lab said, “The reliance on connected devices is impacting us in more ways than we could have ever expected. There is no doubt that being connected gives us the freedom to make modern life easier, but devices are also vital to help people get through different and difficult social situations. No matter what your ‘connection crutch’ is, it is essential to make sure your device is online and available when you need it most.”

To ensure your device lifeline is always there and in top health – no matter what the reason or situation – Kaspersky Security Cloud keeps your connection safe and secure:

·         I want to use my device while waiting for a friend – is it secure to access the bar’s Wi-Fi?

With Kaspersky Security Cloud, devices are protected against network threats, even if the user needs to use insecure public Wi-Fi hotspots. This is done through transferring data via an encrypted channel to ensure personal data safety, so users’ devices are protected on any connection.

·         Oh no! I’m bored but my phone’s battery is getting low – what am I going to do?

Users can track their battery level thanks to a countdown of how many minutes are left until their device shuts down in the Kaspersky Security Cloud interface. There is also a wide-range of portable power supplies available to keep device batteries charged while on-the-go.

·         I’ve lost my phone! How will I keep myself entertained now?

Should the unthinkable happen and you lose or have your phone stolen, Kaspersky Security Cloud can track and protect your device from data breaches, for complete peace of mind. Remote lock and locate features ensure your device remains secure until you are reunited.
