Enevate announces ultrafast charging feature for its silicon Li-ion batteries
28 October 2015
Enevate Corporation, developer of a silicon-dominant composite anode material and high energy density batteries (earlier post), announced ultrafast charging for their batteries with HD-Energy Technology. Enevate’s ultrafast charging feature has been demonstrated to provide a 90% charge in 15 minutes (4C charge rate) while increasing energy, capacity and performance when compared to today’s conventional Li-ion batteries.
Enevate’s HD-Energy Technology utilizes silicon-dominant composite anodes for rechargeable Li-ion polymer batteries, with an 25-50% increase in energy density over conventional graphite anode cells. Enevate’s new batteries enable smartphones, tablets, ultra-thin notebook PCs, and drones with longer runtimes in less space and weight.
The charge rate of Enevate batteries can be 5-10 times faster than conventional batteries due to multiple reasons, including faster kinetics of silicon. Enevate’s unique silicon Li-ion batteries deliver both ultrafast charging and high energy density at the same time. The batteries are resistant to lithium plating during charging which allows for cycle life to be maintained even with high charge rates.
—Dr. Benjamin Park, Founder and CTO of Enevate
For example, a 3000 mAh Enevate battery with HD-Energy Technology using a 12 Amp charge (4C rate) achieves 90% capacity in 15 minutes with no degradation in energy or capacity. Using a 6 Amp charge (2C rate), the same 3000mAh Enevate battery charges to 90% in 25 minutes.
Enevate investors include Mission Ventures, Draper Fisher Jurvetson, Tsing Capital, Infinite Potential Technologies, Presidio Ventures – a Sumitomo Corporation company, and CEC Capital.
Lets do it now.

I'm in...where do I sign up to buy some? :)
Seriously, sounds really good. I think that true rapid charge capabilities makes a lot of the "range anxiety" go away. If there stations everywhere and you can recharge in a time that is at least comparable to the time it takes to fill a car up, then a lot of people are more willing to consider it. Especially when you have the added advantage that you can charge at home 90% of the time.

I wonder what the cycle life is like.

@Jeff,
Usually high power goes hand in hand with long cycle life. But it usually goes against energy density.
I'd love to see the full specs on this battery.

A 4C rate isn't awfully high compared to what hybrids require, but 4C charging for EVs is great.
If the battery technology favors EVs over HEVs, there might not be a time when hybrids dominate. It would be a straight switch-over from ICEV to EV.

Will these batteries cope with the harsh treatments and wide temperature variations required for BEVs or fail when parked outside in -40C or +50C?
