※ 引述《zaku7777 (人間蒸發)》之銘言： : 我覺得太難了,要在1000噸以下,達成2200海浬的能力, : 那顆鋰離子電池剛好是頂標,要200wh/kg,才有可能. : 美法現在頂多搞到UUV用的,ASDS也掛了,潛艇用鋰離子電池,恐怕還需要5-10年. : 充電沒充好,它可是會自己燒起來.不然大家早就改用鋰離子電池了. 印象中solid electrolyte的沒那麼爛 我沒有找太多也沒看比較新的 查到一個 不是甚麼頂級期刊 也表示技術困難度也沒那麼高 單單電池上面應該沒那麼慘 做更大會有問題 砍半應該不過分 整合出一個操作性好的系統的問題應該大過電池本身吧 就是空間 散熱 長期穩定跟瞬時出力這些比較麻煩 搞這套東西如果簡單 應該早就有成果了 應該不只是動力源上面的問題 前面是不是有人說過啥沉底魚雷睡雷之類的 ? 也許比較有搞頭 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 節錄些內容 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] --
