NEI and PneumatiCoat partner to develop and market new materials for lithium-ion batteries

NEI Corporation (NEI), a nanotech materials company (earlier post), and PneumatiCoat Technologies (PCT) recently initiated a collaboration to develop, produce, and market coated Li-ion battery materials: cathodes, anodes, and solid electrolytes.

The partnership will help serve the needs of customers interested in enhancing the performance of batteries through the use of Atomic Layer Deposition (ALD) coatings of active material particles. Key features of ALD-coated particles include improved cycle life, enhanced safety, and greater stability and abuse tolerance, particularly under higher temperature and voltage operation.

NEI Corporation has been a source for customized cathode and anode materials used in lithium batteries. The company specializes in developing new compositions and particle morphologies, including nanoscale particle engineering. NEI also has extensive battery research and characterization facility, which includes multi-channel cell testers.

PneumatiCoat Technologies is a pioneer in autonomous coating systems that allow for high-rate manufacturing of ALD protected particles used in batteries and related energy storage devices. The ALD platform was originally developed in Europe, and PCT is now facilitating the transition of the ALD platform from slow and expensive to economical, robust and industrially-viable.

The NEI–PCT agreement allows customers access to ALD coatings on a variety of battery material compositions, including mixed metal oxides (Lithium Manganese Nickel Oxide: LMNO, NMC, LMO, NCA); phosphates; silicates; titanates; sulfides; graphite; and silicon-based active materials.

Customers have the flexibility to not only investigate new compositions and chemistries, but also consider the use of different ALD coatings, both passive and lithium-ion conducting. The NEI–PCT relationship provides customers with access to the technology cost-effectively, the partners said.



Almost every day we hear battery improvement but when you look at real performance and prices, than it's the same as before with 0.1% of market share versus regular unleaded gasoline. When they improve one parameter than it's causing drawback on something else, etc.

Im sure that they never will discover a good powerful battery and bev will always be marginal cars and forget trucks, trains, airplanes, ships.


Don't give up too soon on improved lower cost batteries and Extended range affordable BEVs in the post-2020 era.

However, FCEVs may becomea (one on one) replacement for higher value ICEVs starting in 2018 or so.

Lower cost affordable FCEVs may compete with affordable extended range BEVs some 10 years latter?


Yes but it's been 20 years now that they do research and development on batteries and fuelcell and they still struggle and it's not popular on the market so I think that in the next 20 years they not gonna do more good. Probably they don't want to eat their own market of gasoline and diesel. Why commercialize batteries or hydrogen if it cut gasoline car sales ? They only do it to get subsidies from goverments and to prevent other car companies to enter the market. Look at tesla, even with a selling price of 100 000$, they still do not make money and they are about to declare bankruptcy.


Don't give up too soon on Tesla (the BEVs Henry Ford). By 2020 or so, Tesla (and BYD China) will have half dozen extended range EVs (each) on the world market.

By 2020 or so, BYD will have built 10,000+ e-buses. Proterra and a few others may not be too far behind.
