✅ Дешевле литий-ионных. Хорошо там, где стоимость — проблема. ✅ Долговечность. Срок службы в некоторых ситуациях выше, менее подвержены деградации. ✅ Температурная стойкость. Перепады и экстремальные температуры держат лучше. ✅ Спецприменения. В промышленности, военном деле, аэрокосмических отраслях их свойства подходят лучше — например при высоких требованиях к скорости РАзряда.

Да, за литий-ионной технологией прогресс, но никель-кадмиевые и никель-металлогидридные аккумуляторы всё ещё играют свою роль благодаря своим уникальным свойствам и экономичности.

🔻 Чем Ni-Cd отличается от Ni-MH мы рассказывали отдельно

ラスボス – バッテリー選び その1

パーツ選択のラスボス「バッテリー」。

コレが無いと何も始まらないですね。 子供の頃は、タミヤのニッカドバッテリー使ってましたが、 あっという間にバッテリー切れるので、3本位いつもポケットにいれてた記憶があります。

そんなバッテリー事情も、調べると知らぬ間に進化していました。

Ni-Cd – ニッケルカドミウム

Ni-MH – ニッケル水素

Li-Fe – リチウムフェライト

Li-Po – リチウムポリマー

RCではこの4種類が使われています。 初心者にはニッカドかリフェが良いそうです。 理由は管理が難しくないからだそうです。 管理というのは、保管や充電方法ですね。 リポは扱いを間違うと危険だというのは有名な話ですね。

値段は例外はあるにせよ、 ニッカド＜ニッケル水素＜リポ＜リフェ という感じでしょうか。

実際には高いリポもあるけど、 普及率からするとリポがメイ…

Batteries might seem like they come in every shape and size that you can imagine. But as electronic devices become tinier and skinnier without reducing their power and energy demands, they challenge engineers to design batteries that can fit into smaller spaces without compromising on performance. Researchers have used non-traditional techniques to fashion one possible solution -- a powerful 3-D lithium ion battery with a footprint on the order of one hundred grains of salt. Their work appears May 3 in the journal Joule.

"For small sensors, you need to re-design the battery to be like a skyscraper in New York instead of a ranch house in California," says senior author Bruce Dunn, a professor of materials science and engineering at the University of California, Los Angeles (UCLA). "That's what a 3D battery does, and we can use semiconductor processing and a conformal electrolyte to make one that is compatible with the demands of small internet-connected devices."

Even the most innovative two-dimensional batteries are limited in the shapes they can take -- the basic battery takes a slice of anode and a slice of cathode and packs an ion-conducting electrolyte between the two to complete the circuit. On the other hand, there are in principle innumerable ways to craft a 3D anode and a 3D cathode that snap together like puzzle pieces (still necessarily separated by a small amount of electrolyte). The setup chosen by Dunn's group is called a "concentric-tube" design, where an array of evenly spaced anode posts are covered uniformly by a thin layer of a photo-patternable polymer electrolyte and the region between the posts is filled with the cathode material.

Despite this apparent simplicity, many researchers have only been able to build half of a 3D battery, creating anodes and cathodes that are stable on their own, but fail when trying to assemble these electrodes into one functional battery. Meanwhile, nearly all of the 3D batteries which have been assembled have not been significantly better than ordinary two-dimensional versions. Dunn and postdoctoral scholars, Janet Hur and Leland Smith, overcame these hurdles by taking methods normally used to make semiconductors and modifying them to carve silicon into a grid of precisely-spaced cylinders that they wanted for the anode. "That's something the battery world just does not do," Dunn says.

To complete the battery, they applied thin layers of electrolyte to the silicon structure and poured in a standard lithium-ion cathode material, using the anode as a mold to ensure that the two halves would fit together just right. The resulting battery achieved an energy density of 5.2 milli-watt-hours per square centimeter, among the highest reported for a 3D battery, while occupying a miniscule 0.09 square centimeter footprint and withstanding 100 cycles of charging and discharging.
