Bosch ac­quires US elec­tric car bat­tery devel­oper Seeo

The Pak Banker - - 6BUSINESS -

Auto parts maker Robert Bosch [ROBG.UL] has bought Seeo Inc, a Cal­i­for­nia-based com­pany that has de­vel­oped next-gen­er­a­tion lithi­u­mion bat­ter­ies that could dou­ble the range of elec­tric cars.

Elec­tric ve­hi­cles have failed to take off with main­stream cus­tomers be­cause cur­rent bat­tery tech­nol­ogy lim­its the op­er­at­ing range of ve­hi­cles to be­low 500 kilo­me­ters (311 miles), and be­cause ve­hi­cles take hours to fully recharge.

Ac­cord­ing to a fil­ing with the state of Cal­i­for­nia, Seeo s bat­tery tech­nol­ogy may help to in­crease energy den­sity by 50 to 100 per­cent, which could sig­nif­i­cantly in­crease the op­er­at­ing range of an elec­tric ve­hi­cle.

Hayward, Cal­i­for­nia-based Seeo has an ex­clu­sive li­cense to core patents from Lawrence Berke­ley Na­tional Lab­o­ra­tory that could help Bosch pro­duce light­weight bat­ter­ies on an in­dus­trial scale. Seeo s ad­vanced lithium poly­mer cells have an energy den­sity of 350 watt-hours per kilo­gram, roughly twice the level of bat­ter­ies used in to­day s elec­tric ve­hi­cles. Tra­di­tional bat­tery packs use elec­tro­chem­i­cal energy stor­age and be­come less safe or re­li­able the more pow­er­ful they are, to the point where the bat­tery may catch fire. Be­cause Seeo bat­ter­ies are based on non-re­ac­tive solid poly­mer elec­trolytes, they are less prone to the flaws that be­set cur­rent-gen­er­a­tion cylin­dri­cal and pris­matic lithium-ion bat­ter­ies. The trans­ac­tion closed in mid-Au­gust and fi­nan­cial de­tails have not been dis­closed, a spokesman for Bosch said.
