Re: [Electric Boats] NiMH Batteries Suppressed

 

NiMH is really good for high power applications expecially for HEV as you know. However, it's really expensive compared with current low end LiFePO4 battery (large cell, low discharge rate). NiMH is made from expensive metals and rare earth materials so it's cost will rise together with the market needs, but lithium ion battery does not have such a problem. That's why NiMH battery is seldom seen on the market except for the Prius and Civic hybrid cars. Patent may not be a key issue.   --- 12年6月12日，周二, Matthew Geier <matthew@acfr.usyd.edu.au> 写道： 发件人: Matthew Geier <matthew@acfr.usyd.edu.au> 主题: Re: [Electric Boats] NiMH Batteries Suppressed 收件人: electricboats@yahoogroups.com 抄送: "Kirk McLoren" <kirkmcloren@yahoo.com> 日期: 2012年6月12日,周二,上午9:03   On 12/06/12 05:49, Kirk McLoren wrote: > > > I think some of these patents expire 2014 > It's depressingly easy to extend the patents if some one thinks there is some commercial value in holding them... There is entire branch of the legal profession dedicated to it these days.
