ExxonMobil Chemical to Showcase New Lithium-ion Battery Separator Film Technology at EVS-23

ExxonMobil Chemical and ExxonMobil’s Japanese affiliate, Tonen Chemical, will present new separator film technologies for lithium-ion batteries at the upcoming 23rd Electric Vehicle Symposium and Exposition (EVS-23) in Anaheim, Calif. on December 2-5, 2007.

In May at the AABC event in Long Beach, ExxonMobil and Tonen introduced new separator film for lithium-ion batteries featuring significant improvements in porosity and thermal properties compared to its predecessors. (Earlier post.)

By developing new film technologies that allow lithium-ion batteries to meet hybrid and electric vehicle requirements, ExxonMobil Chemical is helping to make next generation vehicles more energy and cost efficient, as well as lighter. We are currently working with industry-leading battery manufacturers to expand the boundaries of current hybrid and electric vehicle applications.

—Jim P. Harris, senior vice president, ExxonMobil Chemical Company

Sooner or latter, fossil fuel will run out and the Oil Cos will have to use their huge resources somewhere else.

It seems logical for Oil Cos to progressively switch to batteries (Electrical Energy Storage Units) and clean power generation plants.

If their involment can accellerate the arrival of affordable PHEVs and BEVs, why not.


Just as long as they're not planning to pull a Cobasys on us.

Their chief's publicly asserted that there is no prospect for Hybrids, Solar, Wind, Bio-fuels when those sources were growing at 20 % every year and last year, oil consumption Worldwide grew only 0.7 %.

This could be the reason why BP is very much involved in PVs, ethanol and butanol production and feed stocks.


Lets just hope they don't figure out some killer solution, and then prevent anyone researchers/marketers from using it, by just sitting on the patent.
