Ukrainian ultracapacitor hopeful Yunasko is looking to set up large-scale manufacturing in China after proving a product that works at up to 100ºC.
“Right now, our company is focused closely on customised solutions,” said project manager Sergii Tychina. “We have limited manufacturing capabilities here in Ukraine [but] we have partners in China.”
The news last month that Yunasko’s technology had passed independent high-temperature tests at JME, a US-based firm owned by ultracapacitor expert Dr John Miller, has sparked a search for strategic partners, Tychina said.
The tests showed Yunasko’s ultracapacitors could last 2,000 hours, or about a million charge-discharge cycles, at 100ºC with an operating voltage of 2.39V.
“This is the highest operating voltage of any solution-based ultracapacitor,” said Yunasko in press materials, “at a fraction of the cost typically seen for ionic liquids.” Read more →

According to the latest predictions, the cost of electric vehicles is likely to be the same as their internal-combustion counterparts by 2022, while by 2040 this price is predicted to become even lower.
Skeptics would say that predictions should not be taken too seriously as they are always to some extent based on merely subjective opinions. This is absolutely right, just like is the fact that electric car sales continue to increase.
Statistics say that global sales increased by approximately 80% in 2015 compared to 2014, from 315,519 to 565,668, while by the end of 2016 the number of electric cars on the world’s roads is expected to exceed 2 million.
By 2040, for instance, electric vehicles would account for 35% of all new vehicle sales. What this implies is that even if some years or numbers in such sort of predictions may be inaccurate, the tendency of sales growth is definitely strong and cannot be doubted. Read more →

Systems integrator Powin Energy could gain an award today for a seemingly bizarre energy storage application: using batteries to charge batteries.
The Oregon, USA-based company is among those shortlisted for a 2016 Energy Storage North America Innovation Award for an electric vehicle fast-charging station at the headquarters of microprocessor firm Intel.
The installation, in Santa Clara, California, uses Powin Energy’s Battery Pack Operating System (bp-OS) to manage 30kw and 43kWh of lithium iron phosphate storage linked to 15 SolarWorld PV panels with a capacity of 4.1kW.
The use of batteries for electric vehicle fast charging avoids the need for standard three-phase 208/277/480V AC connections and helps avoid high demand charges, said EV4, the firm that designed and manages the station.
The technology also makes it possible to place charging stations in areas where three-phase AC is hard or costly to obtain.

Lithium-ion’s potential to dominate the stationary storage battery sector may be stronger than previously thought, according to the implications of a new study.
Research published last week by the analyst firm Bloomberg New Energy Finance (BNEF) shows a glut of second-hand lithium-ion (Li-ion) batteries from the auto industry could cut battery storage costs significantly.
By 2018, says Used EV batteries for stationary storage: second-life supply & costs, the cost of repurposing batteries for second-life applications could go down to as little as USD$49 per kWh.
This compares to a cost of roughly $300 per kWh for new batteries at the moment, and $160 for lowest-cost battery chemistries such as the zinc hybrid cathode technology being commercialised by Eos Energy Storage.
Given that BNEF expects around 10GWh of capacity from used electric vehicle batteries to be entering into the stationary storage market by 2025, second-life applications could deal a real blow to the prospects for non-Li-ion chemistries. Read more →

Kreisel Electric has become the latest battery vendor to take on the Tesla Powerwall with the launch of a residential energy storage product today.
The Austrian industrial firm is looking to improve on Tesla’s trailblazing battery pack with a system that uses the same 18650-size lithium-ion cells, with a few significant manufacturing improvements.
Critically, Kreisel uses a laser system to solder connections to each cell in the battery. This is in contrast to traditional manufacturing processes where welding is employed.
The heat generated from the welding process damages cells before they are even used, said Christian Schlögl, head of business development. “With our laser technology we don’t destroy the cell,” he told Energy Storage Report.
The laser manufacturing process helps make sure all of the 8,000 or so cells in each battery have the same capacity and voltage once connected, so there is no need to balance them afterwards. Read more →
California start-up Capacitor Sciences claims to be developing an energy storage medium that could beat lithium-ion batteries on performance while costing around USD$100 per kWh.
The Menlo Park firm is hoping to use nano-structured crystalline thin films as the dielectric material for capacitors with up to 10 times the energy density and 100 times the power density of lithium ion batteries, according to a press release.
Capacitor Sciences says the use of thin film should overcome problems dogging other capacitor manufacturers, such as ill-fated EEStor, which used inorganic dielectric materials too brittle to withstand repeated charging cycles.
“No-one is really working on this class of materials,” said Wolfgang Mack, vice president of business development. “We’re using organic materials. They are waxy in nature. There’s no damage done during charge and discharge.”
Capacitor Sciences’s founder and chief technology officer, Dr Pavel Lazarev, was previously involved with Crysoptix, a liquid crystal display optical films maker, and nanomaterials business Optiva, which went out of business in 2005. Read more →

The world’s oldest battery company isn’t clinging to the past. Leclanché, of Switzerland, is betting on its two newest lines of business for future growth, said Jacques Boppe, the company’s vice president of corporate development.
“Stationary storage is a growth business and transportation is a growth market,” said Boppe.
Both areas were given separate business unit status in January 2015 as part of a turnaround plan that saw Anil Srivastava, the former boss of Areva Renewables, taking the helm of the company in June 2014.
The turnaround followed financial troubles that resulted in Leclanché’s German subsidiary needing a €5m bailout from the Bruellan Corporate Governance Action Fund in 2012.
Boppe said Leclanché is expecting both business units to blossom while it continues to serve its legacy business, creating and distributing custom battery systems for specialist customers such as the Swiss Army, from a third unit. Read more →
Tesla Motors shares were changing hands for mind-boggling amounts ahead of a likely energy storage announcement as Energy Storage Report went to press this week.
The electric vehicle maker’s stock, which was given junk-bond rating less than a year ago, closed at just over USD$230 a share yesterday after having peaked at $237.06 on Monday.
Tesla’s valuation soared at the beginning of the week after Deutsche Bank issued a ‘buy’ recommendation relating to a battery storage announcement due tomorrow.
“Tesla’s announcement may be more significant than the market indicates,” said Deutsche Bank. “While stationary storage is still in its infancy, we believe that there are clear indications that significant growth lies ahead.” Read more →
