GM owned battery start up developing lithium-ions with double the energy density

Sakti3, a small spin-off start up created from the partnership between the University of Michigan and General Motors, is currently developing a line of solid state batteries that could double the energy density of current cells on the market. Li-ion is going to be the material of choice for the next twenty or so years, according to battery makers at the 2009 Automotive Research seminar; so long as developers can manage to pack more power into each cell.

Sakti3 has yet to discuss the technological advances they plan on building upon to double the energy density of their li-ion batteries.

Traditionally, cost has also been a factor holding back the spread of li-ion technology. The cost factor of the technology however, has dropped by 14 points in the last 15 years, according to Compact Power CEO Prabhakar Patil.

Sakti3 claims to have in development a solid state battery that delivers twice the energy as li-ion batteries on the market today, offering consumers twice the power at the same cost as conventional li-ions.

    Thats sounds Awesome But It Would Be great If they can provide double energy density at half $/KWH,
    But its Good That They have taken atleast a step Sooner We could See more improvements

    Good article but Sakti3 is not actually owned by GM. Their financing comes from private equity (Khosla Ventures) and a grant from the Michigan Economic Development Corporation.

    I saw their presentation at an automotive conference and they are also making cost-reduction steps.

    Also, I believe that Prabhakar said cost has reduce 14 times for Li-ion batteries, not 14 points.
