※ 引述《zaku7777 (人间蒸发)》之铭言： : 我觉得太难了,要在1000吨以下,达成2200海里的能力, : 那颗锂离子电池刚好是顶标,要200wh/kg,才有可能. : 美法现在顶多搞到UUV用的,ASDS也挂了,潜艇用锂离子电池,恐怕还需要5-10年. : 充电没充好,它可是会自己烧起来.不然大家早就改用锂离子电池了. 印象中solid electrolyte的没那麽烂 我没有找太多也没看比较新的 查到一个 不是甚麽顶级期刊 也表示技术困难度也没那麽高 单单电池上面应该没那麽惨 做更大会有问题 砍半应该不过分 整合出一个操作性好的系统的问题应该大过电池本身吧 就是空间 散热 长期稳定跟瞬时出力这些比较麻烦 搞这套东西如果简单 应该早就有成果了 应该不只是动力源上面的问题 前面是不是有人说过啥沉底鱼雷睡雷之类的 ? 也许比较有搞头 doi:10.1016/j.elecom.2005.08.006 All-solid-state lithium polymer secondary battery with (LiNi0.5 Mn1.5 O4) by mixing of Li3PO4 节录些内容 Abstract: 5 V-class all-solid-state lithium polymer secondary batteries were prepared by the mixing of solid inorganic electrolyte (SIE, Li3PO4) with LiNi0.5Mn1.5O4 powder. The discharge capacity exhibited >120 and >550 mWh g^-1 at the operation temperature of 333 K. We also prepared a lithium-metal -free battery by using copper current collector at the anode, and exhibit the similar discharge capacity. Our demonstration indicates the marked improvement in the energy density of lithium polymer batteries through a simple preparation, which leads to the manufacture of large-scaled batteries. Introduction A liquid-free lithium polymer secondary batteries (LPBs) have a potential of having a higher capacity with safety than a commercial lithium ion (liquid electrolyte) batteries [1], [2] and [3]. Although poor ionic conductivity in SPE has been a major problem, it has reached up to >10^-3 S/cm at an operation temperature of 333 or 363 K, which is an acceptable level for practical use [4] . However, the cathodes used were limited only to 3 V-class materials, such as V2O5 and MnO2, because ethylene oxide-based SPE is believed to be oxidized over 4 V, according to the theory of the potential window” [5] --
