Li-ion batteries turn 25, showing age

Published

on

This year, Li-ion batteries have been on the market for 25 years. While they have been used in a variety of devices virtually unchanged, they are now beginning to show their limitations, writes DR LORENZO GRANDE, Technology Analyst, IDTechEx.

In 2016, Li-ion batteries (LIB) celebrated their silver jubilee, i.e. they have been on the market, virtually unchanged, for the last 25 years. While this anniversary marks and underscores their worldwide success and diffusion in consumer electronics and, more recently, electric vehicles (EV), the underlying technology begins to show its limitations in terms of safety, performance, form factor, and cost.

In the newly released report by IDTechEx Research, titled Solid-State and Polymer Batteries 2017-2027: Technology, Markets, Forecasts we cover the solid-state electrolyte industry by giving a 10-year forecast through 2027 in terms of numbers of devices sold, capacity production and market size, predicted to reach over $7B by 2027.

The first lithium-based solid-state battery was the lithium-iodine battery, where a sheet of lithium metal is placed in contact with solid iodine. These primary batteries were commercialized in the early 70’s to power pacemaker devices, but it wasn’t until a few years ago that sulphide-based materials, belonging to the thio-LISICON family, finally demonstrated that solid-state batteries can be made rechargeable and possibly outperform their liquid counterparts.

Recently ARPA-E programme director Paul Albertus announced the US-backed “Ionics” initiative, a three-legged roadmap to support R&D on solid-state batteries. With a total investment of $37M, Ionics is poised to become the foundry of US-labelled next generation batteries, because solid-state batteries can enable smaller, safer, and better energy storage devices. This can be achieved by leveraging on the remarkable properties of the solid materials that have been developed over the last years, like garnets, thio-LISICONs, and perovskites.

Companies like Ford Motor, Toyota, Samsung, and Toshiba are already actively working on solid electrolytes, while many hail the technological achievements of French company Bolloré as an initial step on rechargeable lithium metal polymer batteries. At the same time, consumers demand better, long-lasting batteries that will not catch fire in their hands like the Samsung Galaxy Note 7, and solid-state electrolytes have the potential to solve those issues.

These and other factors, including the surge in popularity of electric cars, wearable devices and drones, are pushing the battery industry towards solid-state electrolytes. Solid-state batteries can be made thinner, flexible, and contain more energy per unit weight than conventional Li-ion.

The IDTechEx Research report covers both inorganic solid electrolytes and polymer electrolytes, with an analysis of where these two chemistries will most likely find applications. An analysis on thio-LISICONs and the other 7 solid electrolyte chemistries (garnet, halides, perovskites, argyrodites, LiPON, hydrides, NASICON-like) and polymer electrolytes is given. Additionally, comparisons are made between liquid-based Li-ion batteries and solid-based batteries, as well as between thin film and bulk solid-state batteries.

Data journalism takes top prize in revamped awards

Published

on

The entries to the 2018 Vodacom Journalist of the Year Awards were extraordinarily varied and of an excellent standard, with new categories introduced which are based on content as opposed to platforms. This year, the judges decided that two entries were equally worthy of the coveted Vodacom Journalist of the Year Award.

The first co-winning entry, in the new Data Journalism category, is a set of stories by Alastair Otter and Laura Grant of Media Hack which showed how Data Journalism is shaping the future. The second co-winning entrant is Bongani Fuzile of the Daily Dispatch for his articles in the investigative category on how migrant workers were being ripped off by pension deductions (full citations below).

Convenor of the judging panel Ryland Fisher says: “This year we modernised the 12 categories that journalists could enter their work in and the change was embraced by entrants. In a turbulent time for media, the 2018 entries once again proved that there are excellent South African journalists delivering praiseworthy work, and we commend them for finding new and innovative ways to cover the news.”

Takalani Netshitenzhe, Chief Officer for Corporate Affairs at the Vodacom Group, says: “Vodacom is proud of its 17-year association with these prestigious awards, which make an important contribution to our society through the recognition of journalistic excellence. I’d like to congratulate all of tonight’s winners and, as always, I’d like to pay tribute to our hardworking judges. Ryland Fisher, Mathatha Tsedu, Arthur Goldstuck, Collin Nxumalo, Elna Rossouw, Patricia McCracken, Megan Rusi, Mary Papayya, Albe Grobbelaar and Obed Zilwa: thank you for making these awards a continued success.”

Veteran journalist and media stalwart Ms Amina Frense is the winner of the 2018 Vodacom Journalist of the Year Lifetime Achiever AwardShe has spent decades in mainstream media both locally and internationally. She is a former Managing Editor: News and Current Affairs at the SA Broadcasting Corporation. She has worked in many countries abroad as a producer and a foreign correspondent, has written two books and is also a founding member of SANEF where she still serves as a council member (full citation below).

The overall winners share the R100 000 main prize. National winners in the various categories are as follows, with each winner taking home R10 000:

The entries in this category were of an exceptionally high standard. One entrant stood out and became the unanimous winner. This journalist showed an exceptional skill for story-telling and for finding unexpected angles and unknown facts. For his stories about Musangwe’s fight for recognitionAge cheating in SA football, and Hansie Cronje revisited, the winner is Ronald Masinda, and the team of Gift Kganyago, Nceba Ntlanganiso and Charles Lombard from eSAT TV.

Cons exploit Telegram ICO

Published

on

Kaspersky Lab researchers have uncovered dozens of highly convincing fake websites claiming to be investment sites for an initial coin offering (ICO) by the Telegram messaging service. Many of these websites appear to belong to the same group. In one case alone, tens of thousands of US dollars’ worth of cryptocurrency were stolen from victims believing they were investing in ‘Grams’, Telegram’s rumoured new currency. Telegram has not officially confirmed an ICO and has warned people about fraudulent investor sites.

In late 2017, stories started to circulate that the Telegram messaging service was launching an initial coin offering (ICO) to finance a blockchain platform based on its TON (Telegram Open Network) technology. Unverified technical documentation was posted online, but there appears to have been no confirmation from Telegram itself. The resulting confusion seems to have allowed fraudsters to capitalise on investor interest by creating fake sites and stealing vast sums of money.

Kaspersky Lab researchers have discovered dozens of such sites, possibly belonging to the same group, claiming to sell tokens for ‘Grams’ and inviting investors to pay with cryptocurrencies including Bitcoin, Ethereum, lice litecoin, dash and Bitcoin dash. A record of transactions on one site revealed that the scammers were able to steal at least $35,000 US dollars’ worth of Ethereum from investors.

The researchers found that some of the websites were so convincing that even after Telegram and others began to issue warnings, they were still able to recruit potential investors. Most use a secure connection, require registration and generate a unique online wallet for each new victim, making it harder to track the money.

Judging by the content of the fake websites, it appears they may have common ownership. For example, several have the exactly the same ‘Our Team’ section.

“ICOs are a fairly risky investment and many people don’t yet fully understand how they work, so it is not surprising that high quality fake websites, with seemingly reassuring features such as a secure connection and registration are successful at luring people in. People wishing to invest in an ICO would do well to check with the company behind it and make sure they know exactly who they are giving their money to, or they may never see it again,” said Nadezhda Demidova, Lead Web-Content Analyst, Kaspersky Lab.

Kaspersky Lab offers the following advice for users considering investing in an ICO:

  • Check for warning signs: for example, some of the fake Telegram ICO websites had the same wrong image next to the name of Telegram’s Chief Product Officer.
  • Do your homework: always check with the brand’s official site to verify the legitimacy of the investment site and, if necessary contact the company’s ICO teams before investing any money or currency.
  • Use reliable security solutions such as Kaspersky Internet Security and Kaspersky Internet Security for Android, which will warn you if you try to visit fake internet pages.
