Hitachi Takes the Lead in Lithium Ion Battery Technology

Advances in Lithium Ion Technology have been fairly consistent, but many of them are relatively small and provide little to helping improve the overall effect of battery powered devices. Hitachi has broken this trend with a battery they say could become the new standard for the automotive industry.

The new battery is said to provide a 4500 watt output density, which is a respectable amount more than Hitachi's previous Lithium-Ion Battery series. The lifespan of the battery is also said to be over 10 years, meaning it should last 20% longer than the best Li-Ion batteries currently available.

Hitachi plans on mass producing the new power source, using similar methods they are currently employing for their oversized batteries.  If they are as successful as their predecessor, more than 600,000 of the high power batteries will be gone within 10 years.  


Assuming they are as efficient as the initial testing has shown, they could also very easily make their way into the new hybrid electrics we are ever so patiently waiting on. More details should be available within the next few weeks.

Hitachi might be the leader if power density was the problem. Unfortunately for them, the area in which batteries need to be improved is energy density. Tesla proves that batteries pack all the punch necessary, it's the distance a battery can take you that needs attention.
