Hanergy and Bollore Group to build solar electric vehicles

Hanergy Holding Group subsidiary, Donghan New Energy Automotive Technology inked a strategic cooperation framework agreement with Bluecar, a subsidiary of France's Bollore Group to mark the beginning of new era in the field of solar electric vehicles.

Solid-state electrolytes and the quest for a safer battery

2016 was the year of Li-ion batteries' silver jubilee, a coming of age that has not been hassle-free, as Samsung's Firegate showed us. This year might mark the first significant switch to new materials in the electrolyte compartment, with both large and small companies trying to bring inorganic and polymer electrolytes to commercial fruition.

Solvay

Dr Lorenzo Grande spoke to Thierry Baert and Thomas Mathivet from Solvay. They are expanding their battery material portfolio by developing gel polymer electrolytes that are based on their proprietary PVDF binders.

Solid-state batteries to the rescue - better, longer-lasting

In 2016, Li-ion batteries 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, the underlying technology begins to show its limitations in terms of safety, performance, form factor, and cost.

Inorganic and polymer electrolytes: what chemistries are out there

In this article, analyst Lorenzo Grande looks at the available chemistries both in terms of inorganic and polymer electrolytes, with mentions of which company is working on which technology. A watch list is also provided that includes companies worth keeping an eye on in the solid battery space.

Hydro Quebec

Hydro Quebec is a Canadian company developing lithium metal sheets for lithium metal batteries. They can manufacture said sheets down to 20 micron thickness.

Blue Solutions

Blue Solutions is a French company that produces Li-ion batteries that employ a lithium metal anode and a polymer electrolyte. These rechargeable batteries are used in Bolloré's Bluecar, an electric microcar with a 250 km driving range.

Citroen announces electric e-Mehari

The E-MEHARI features advanced technology. It is an all-electric vehicle with battery technology based on the expertise of France's Bolloré Group.

€9.8 million for deploying graphene ultracapacitors

Skeleton Technologies plans to use the funds for ramping up production of their graphene-based ultracapacitors to meet the strong demand for electrical engineering applications.

Renault and Bollore form electric vehicle partnership

Renault and Bolloré are joining forces to promote electric vehicles (EVs) as part of three agreements relating to industrial cooperation, the founding of a joint-venture to sell EV car sharing solutions and a feasibility study on the development of a specific new Renault vehicle for car-sharing plans.

Supercapacitors for electric vehicles are gaining traction

The replacement of batteries means grabbing a chunk of the lithium-ion battery market in particular but also inroads into lead-acid and nickel metal hydride territory.

Bollore says Blue Solutions share offer oversubscribed

Blue Solutions, the battery company being listed by Vincent Bollore, has already filled the order book for its upcoming share sale, the French industrialist said on Wednesday.

Supercapacitors increase range of electric vehicles

Supercapacitors are increasing the range of electric vehicles in several ways and by doing so they are hugely increasing the addressable market for those vehicles. Typically, they last for the life of the vehicle regardless of how many cycles are endured.

Winners in traction power appear first in buses?

Large electric vehicles are not sold on up-front price but on performance and cost over life. They are mainly bought by government including local government, the military and with government funding of others. Innovation is therefore usually first seen in large electric vehicles.

Supercapacitors improving faster than batteries

Supercapacitors replace lithium-ion batteries. Lithium-ion batteries replace nickel metal hydride and lead acid batteries. There are side stories of course. Some supercapacitors replace electrolytic capacitors and others create new applications. However, in this article, we concentrate on replacing lithium-ion batteries.

All eyes on Supercapacitors

Supercapacitors (ultracapacitors) are now center stage for designers of electronics and particularly power circuits. This is because they are improving faster than the batteries and electrolytic capacitors they increasingly replace. More subtly, they reduce the need for and danger from lithium-ion batteries. For example, when placed across a rechargeable battery, they protect it from fast charging and discharging and allow more of the energy in the battery to be utilised. Learn more ...

Electric cars: Success by a different route

Everything about an electric car is facing total change. Different materials for bodywork, structural components leading to smart skin, laminar electrics, printed electronics and totally new components are coming along.

Vibrancy in electric buses contrasts gloom in electric cars

The market for electric buses and taxis at ex-factory prices will rise 8.7 times from $6.24 billion in 2011 to $ 54 billion in 2021. Of course, the largest part of that will be buses and detailed figures to 2022 are given in the report.
