Swiss researchers examine solid-state battery secrets

Swiss researchers have lifted the lid on electromechanical processes that take place in solid-state batteries in a move they say could make the technology safer and more efficient for use in electric vehicles.

Researchers at the Paul Scherrer Institute (PSI) used X-ray tomography to observe the batteries “more precisely than ever before” and discovered how fissures in the battery material propagate.

Indian start-up plans next stage of second-life lithium-ion ESS development

Fri, 01/27/2017 - 12:34 -- Paul Crompton

An Indian start-up has developed a prototype energy storage system using recycled lithium batteries from electric vehicles.

Totus Power has field trailed a prototype/proof of concept in India, but remains 12 months and $350,000 away from doing a pilot with a pre-production prototype.

The company can take a used EV module, connect it to its own battery management system and charge an ESS from a solar or a plug-in power source.

It can be used to replace lead-acid batteries or fossil fuel energy generation, said Siva (Shiv) Rajendran, founder and CEO of Totus Power

He told BBB the company has all the infrastructure/relationships to make up to 5,000 units a year.

The company is currently sourcing end-of-life batteries from an unnamed ‘large’ automaker’s ‘most popular EV model’.

Rajendran said: “The deal is in the works, hence I can’t share the name yet. This is already a large supply pool, which we will take a few years to fully utilise. Conservatively, we can make 10,000 units a year - if not more. 

“It seems very simple to manufacture a EV battery down to a Totus Power product.

“The Modules are the building blocks of a EV battery and is shipped in boxes to us by the automaker directly. We already pre decide what level of quality these used modules are, i.e SOH%). 

“Some of our knowledge is in correlating this SOH% to real world life, along with the supply chain and associated shipping and recycling regulations.  

“But they say the devil is in the details: So over the next 12 months, when we start writing our assembly/manufacturing procedures, I will have a better handle on what ‘simple to manufacture’ actually means.”

However, because the firm is mainly self-funded and has only secured a few grants to date, its speed of execution is dependent on more cash becoming available.

Lithium boss airs concern on future of battery industry

The boss of China’s second biggest lithium carbonate supplier has questioned if growth in lithium-ion battery production can be sustained by electric vehicles.

For the first time Wang Xiaoshen, executive vice president Jiangxi Ganfeng Lithium (JGL), has expressed concern the growing electric vehicle market, which drives lithium-ion battery demand, is unable to continue sustainable growth, particularly in China.
