The only problem is, a high-voltage cathode (-) requires a very low-voltage anode (+)
なんですよね。正極負極を間違えてる？とか思ったけど、さらに原文たどるとちょっと長いんですが
The researchers chose to use a water-based electrolyte, （色々略） such as iron, copper, carbon and nitrogen – all of which are extremely inexpensive compared with lithium. The sole significant limitation to the new electrode is that its chemical properties cause it to be usable only as a high voltage electrode. But every battery needs two electrodes – a high voltage cathode and a low voltage anode – in order to create the voltage difference that produces electricity. The researchers need to find another material to use for the anode before they can build an actual battery.
高い電位ではなく低い電位では？ (スコア:1)
開発したのが電位の"低い"正電極だから、それに応じて(実用的な出力電圧を得るために)低い電位の不電極が見つからないのでは？
#致命的になんか勘違いしてる？

だそうです。
たしかに今回は正極で、負極を探してはいますけど、「a very low-voltage」とか「(特別)見合う低い電位の」とかは言ってなくて、真相
Re:高い電位ではなく低い電位では？ (スコア:0)
なので、「バッテリーには、高い電圧側の陽極（電池のcathode）と低い電圧側の陰極（電池のanode）の、二つの電極が必要なんですよー」という、極めて当たり前のことを述べているんじゃないかと。
伝言ゲームで話がおかしくなってしまったのでしょうね。
