The secret to the long-lasting lithium-ion? In current designs, the tin that's used for the battery's negative electrode weakens through continual charging and recharging. The new design, however, calls for tin-coated resin that stabilizes the electrode and prevents deterioration. Why didn't we think of that? Look forward to seeing these exciting, new batteries debut in electric scooters sometime this year

But us garage guys will never see them in all likelihood. And that's if they aren't vaporware to begin with.

Cathode conductive polymer battery / capacitor

現在リチウムイオン電池を用いたビジネス展開で一番問題となっている製造コストと寿命の問題を解決する、 全く新しい導電性高分子電極(正極)を開発しました。 To solve the problem of production cost and life has become a business development issues for the most current lithium-ion batteries, brand new conductive polymer electrode (the cathode) has been developed.

電極素材１００％が導電性高分子でできているため、導電性の低下がなく 、充放電性能は鉛電池の3倍の性能を達成しました。 Because the conductive polymer is made ​​of 100% of the electrode material, without a reduction in conductivity, charge and discharge performance was achieved three times the performance of lead-acid batteries. また、 優れた耐久性・寿命は導電性高分子本来の特性であり、蓄電デバイスとして高いレベルで全体の性能を達成しました。 In addition, the lifetime durability are inherent properties of conductive polymers, has achieved a high level of overall performance as a storage device.

製造コストは電極素材の導電性高分子は樹脂であるため価格が安く 、また、電極の製造方法は ロール to ロールによる電解重合の1工程で連続製造されるため非常に安くなり、 既存金属酸化物正極の1/10で非常に低コストの製造が可能となります。 Production cost of a conductive polymer electrode material because it is cheap and plastic, and method of manufacturing the electrode becomes very cheap because it is produced in one step of electropolymerization with continuous roll to roll, metal oxide existing enables production of very low cost 1 / 10 of the positive electrode.

I have 2 Texaco 36v ebike nimh packs about 11 years old that still get er done !

lol..

Is honda making electric scooters??? and what kind of batteries they were using in it?

Batteries that last 20years seems like more of a curse than an advantage. lol

You would just have to feel more guilty about chucking them in 5 years when battery technology became so much better that you don't want them anymore. lol

oh, i think i could find a use to re-purpose them somewhere if you wanna chukem my way.
right hombrewolf?

20 year lifespan would be fine with me for some things, I'm so happy with my cellphone batteries that seem to last 6 months. Likely that's the charger more than anything though.

20 year lifespan would be great for some critical things, power back up units, smoke alarms, solar off grid. But still too expensive to beat lead as of today on lots of that stuff.

 

[muffildy]

sweet; i hope it comes to market at a reasonable price
it sounds even better than the SCiB batteries by toshiba which only get 6000 or so cycles and cost too much.

Like my Texaco packs !

TVs used to last 5 to 10 years.

Now they are made to last 2 years or so.

Computers and laptops too.

That may be why I am finding so many laptop batteries so cheap ! They are for laptops older than 2 years and who wants a laptop that old ?

The batteries are outlasting the laptops !

They are the only part of a laptop that is overbuilt !

I have been fixing computers and TVs for over 20 years now and caps are getting worse !

I bought some cheap overhead lights at Lowes about 6 years ago and just a few months after I bought them they started messing up.

I took them apart and found 2 bad caps in each one.

I replaced those caps with ones about 10 years old from old tv boards.
They still work !

Yeah, I want more than a 20 year lifespan outta them. They should be biodegradeable. In fact, they must be really light ... (less then 100 calories each and completely edible).

LiFePo4 already lasts 10+ years...

 

[muffildy]

only lasts that if your very careful with the C rate and the charge/discharge percentages. Its very dependent on temperature.

According to this one:
http://www.fmadirect.com/support_docs/item_1229.pdf
Pg 4
"In general, cycle life is about flat up to an operating temperature of 140° F.
Above that life deteriorates at about 12 cycles per degree F."

Another thing to consider is that lithium loses a percent of its total AH every year regardless of if the battery was even used or not; varies with brand and its hard to get exact figures, but 2%-10% loss of capacity per year looks to be what to expect. so even if you treated your batteries very well, they would still not be able to give you the juice after a period of time.

A few of the newer lithium tech batteries out there do away with these problems, but they arent being sold as of yet.
