锂电专利存隐患 标准体系缺失
来源:电动车时代网 日期:2011-12-23 作者:全球电池网 点击:

目前,中国锂电池产业发展主要有两条技术路线:一是磷酸亚铁锂系,二是锰酸锂系。这两种技术路线各有优缺点。锰酸锂系起步早,技术较为成熟,其缺点是单体电池寿命短,满充满放2000次,耐高温性能差。磷酸亚铁锂系是目前国内大多数企业采用的技术路线,其缺点在于两个核心技术的专利一个在美国,一个在加拿大,而中国发展磷酸亚铁锂系绕不开这两个核心技术,因此存有知识产权隐患。

锂电池具有高密度、无记忆、转换效率高、重量轻、寿命长、无污染等优势,而且从全生命周期看,其成本已低于铅酸电池。因此,动力锂电池将成为新一代动力电池的发展方向。
