"Say hello to CODA, All-New. All-Electric. All Good. Powered by our state of the art battery system. CODA will drive up to 125 miles per charge in hot or cold temperatures, running AC/Heat, driving up and down hills, in stop & go traffic. Real useful range in all seasons and driving conditions thanks to Active Thermal Management."
If we can marry Tesla's abilities and ambitions with new Lithium batteries for Electric Cars from Envia Systems we can have the US based mass market production base for the Electric Cars.
"Tesla Model S will bring Electric Cars into the headlines again. Responsible Luxury, High-End performance and Electric Car - it is all represented by Tesla Model S now. The next step will be the real Electric Cars for the mass market. Volume will bring down the cost of the lithium batteries, battery leasing schemes will reduce the entry cost of Electric Car ownership and then we can never look back on the 19th century technology of controlled explosions under the hood burning Oil."
One of the main barriers to mass EV adoption is range anxiety. Most electric vehicles have an 80-100 mile range. The key factor in determining the vehicle’s electric range is the energy density of the battery. Current technologies max out at 180 Wh/kg. Envia’s technology enables a 2-3X improvement in vehicle range compared to other Lithium cell chemistries.
Enhanced Safety
Another barrier to EV adoption is the perceived safety risk of lithium batteries resulting from recent post-crash fires of some electric vehicles. Thermal runaway in a lithium battery occurs when the cell exceeds the critical temperature above which an increase of the cell temperature is irreversible due to the exothermic heat associated with structural changes of the anode, cathode and the electrolyte. Although the thermal reactions are associated with solid electrolyte interface (SEI) decomposition at the anode¹, progressive reactions, which cause the cells to catch fire, are associated with the cathode.
Differential scanning calorimetry (DSC) is one of the techniques used to evaluate the heat associated with various components of the Li-ion battery. DSC is used to analyze the onset of the reaction, which is shown by an increase in an exotherm.
Layered cathode chemistries such as NCA have high specific capacities (although not quite as high as that of Envia’s HCMR cathode). As we shall see in the following discussion, the thermal stability of NCA is not as good as Envia’s cathode either.
The chart to the right shows the results of a DSC study² comparing NCA and a manganese-rich layered-layered cathode very similar to Envia’s cathode. Please note that the NCA material was only charged to 4.2V whereas the manganese-rich cathode was charged to 4.6V (for higher specific capacities).
In the DSC study, NCA shows one major exothermic peak around 275ºC followed by smaller complex exothermic peaks. However the major exothermic peak starts around 200ºC and
reaches its maximum at 275ºC. This is associated with structural changes in association with the oxygen loss. The following multiple peaks are associated with progressive decomposition of the cathode. However in case of the cathode material similar to Envia’s, only one major peak is observed around 275ºC with an onset temperature around 260ºC.
The higher onset temperature implies a higher thermal stability of the Envia-like cathode compared to NCA. The sharper peak in the manganese-rich cathode also implies the lack of a continuous reaction thereby reducing the amount of heat produced during any event and lessening the likelihood of a thermal runaway.
Envia conducted its own nail penetration testing using 20Ah and 40Ah cells per USABC test protocols to validate its material. Cells made with Envia’s HCMR™ cathode passed the nail penetration test while cells with other layered chemistries did not perform well.

The 2012 Empulse has a 6 speed transmission as standard equipment. The Integrated Electric Transmission (IET™) - IET™ is a mechatronic propulsion unit that emulates the feeling and performance of a traditional internal combustion engine, with a specially developed electric motor, clutch and gear shift, that enables the 2012 Empulse to accelerate hard from the line up to a high top speed, something that is just not possible to achieve with a single ratio electric motorcycle. The 2012 Empulse is also the world's first production electric motorcycle to feature water cooling.

"We have more promotion from Lomiko Metals and more colours to the potential of its Graphite project in Canada. Graphite is in the headlines of news letter writers - James Dines has made his pick as well, now the exploration results will separate the pump and the real projects."
Canada-based graphite exploration company Lomiko Metals is charging ahead in its effort to develop and expand its graphite resource base in Quebec.
Vancouver, BC (PRWEB) May 29, 2012
Canada-based graphite exploration company Lomiko Metals (TSX:LMR) is charging ahead in its effort to develop and expand its graphite resource base in Quebec. - (Financial Press)
In the last few weeks the company has surged past multiple major milestones on its way to capitalizing on the ongoing and resilient graphite boom. The company was encouraged with the detailed information on its Quatre Milles Property and has purchased the 2,180 Ha Quatre Milles West Property which covers similar geology.
Lomiko revealed in a May 22nd press release Graphite and Zinc Outlook is Favourable Through 2013 that Simon Moores of Industrial Minerals reported China, the dominant global supplier of graphite, had cut exports in January and February 2012. The total graphite export reductions were by 55.3% and 60.1% respectively from 2011 level exports from Hunan Province.
While China was cutting supplies to the world, Lomiko continues to advance towards stated objective of mounting “an aggressive exploration campaign on the Quatre Milles Graphite Property with a complete compilation of historic geologic work followed by surface mapping, prospecting and follow-up diamond drilling.”
The company’s development from this point will be centered on the exploration and development of its Quatre Milles graphite property in Quebec’s graphite belt.
The program will cover the most highly prospective graphite-bearing areas on the nearly 1,600 hectare property which covers 28 contiguous claims.
The program will include all of the elements of the “Phase I drilling” program advised by Consul-Teck Exploration in the in the Quatre Milles NI 43-101 report.
The details from the report state:
During Phase I, exploration work will be destined to validate and delineate the mineralize intersection drilled in 1991. This core will be used to evaluate the possibility of:
1) Determining the continuity of the mineral composition of the graphite intersection to a vertical depth of 75 metres
2) Carrying out chemical analysis and metallurgical testing of the whole length of the mineralize core for graphite.
The drilling program will encompass a total of 1500 meters as recommended in the study of the project. Each drill hole is expected to go to a depth of 100 meters. They will be spaced approximately 50 meters apart.
The holes will be drilled along the electromagnetic (EM) signature Lomiko has identified on the project which, when combined with surface geological work and historical results, signifies a significant likelihood of in-demand and highly valued large flake graphite.
Past analysis of the Quatre Milles property demonstrated the EM signature stretched for approximately 1.8 kilometers. The Phase I drill program and consist of between 15 and 20 holes when completed in order to cover the entire area.
The assay results of the program will likely start being made available within a few months.
Finally, Lomiko has added to its team of experienced mining and mining sector-specific professionals.
The company has recently announced Kumara Rachamalla to the board of advisors. Rachamalla is a former director of Holmer
Lomiko has delivered on everything it has set out to do so far. The drilling results will guide the company’s future development. But at this point, it’s still one of the few companies in the graphite sector which has successfully advanced to the drilling stage of exploration.
Lomiko Metals trades on the TSX Venture Exchange under the symbol “LMR.” It’s also listed in the United States under the symbol “LMRMF.”
The company currently has a market capitalization of just over $5 million.
