New Battery Tech From Japan Could Supercharge EVs 81

Today, a Japanese startup called Power Japan Plus unveiled a new battery chemistry that could significantly improve transportation batteries. In testing, the recycle-able cell has completed more than 3,000 charge/discharge cycles with virtually no performance degradation, meaning that it could conceivably last the lifetime of a car. They company won't yet provide too many details due to pending patents, and won't even say who its first customer is — but the chemistry requires 'specific and proprietary changes to the nanostructure of the carbon crystals.'"

    Long lasting batteries are great but not as important as lower cost and higher capacity to weight ratio...

    Exactly. The energy density of these cells are very average at best.

    It's nice that they last a long time as that makes them very useful for certain applications, but for EVs that's not the major issue preventing EVs from being more appealing. The major issue is energy density and cost.

    Extreme durability might help with the cost aspect as batteries would hold more value for re-use after a car is otherwise useless, but it would be for other applications such as perhaps grid-storage where having batteries that basically last forever would be very useful.

    I disagree. This helps EVs in two ways. Once, designers no longer will have to oversize battery packs in anticipation of degradation. (Primarily for series hybrids which will probably come out in combination with the 25 HP wave disk generator....) And as you said, resale value. But resale value is a huge thing, so don't understate it.

    Except if batteries last basically forever, having "swapping stations" where a robot replaces your car battery with a fully loaded one becomes a lot more feasible, since you no longer need to worry about the difference in condition between the old and new battery. That, in turn, makes energy density less relevant, which allows smaller batteries, which brings down the costs. And low cost upfront combined with lower costs of operation combined with basically no maintenance needed makes for a very appealing vehicle for lower-income demographics, especially when these cars start appearing for sale used.

    That is NOT the major thing holding swapping stations back. To make swapping stations feasible you need a standardized power pack installed in a standardized way compatible with a battery pack swap. This standardization need to be agreed to by a substantial market share of electric vehicle manufacturers - enough to justify the enormous infrastructure costs involved in building out a network of swapping stations. Furthermore there need to be enough electric vehicles already on the road to justify the build out.

    Frankly the durability of the battery packs is pretty far down the list of problems with swapping stations.

    Considering the fact that Beats is a fashion brand (they certainly don't sell anything that lets you hear music), and Apple being a more popular fashion brand, Apple buying Beats does make Beats less overrated. Afterall, the only thing that gives any value to Beats --the branding-- has improved.

A failure will not appear until a unit has passed final inspection.

Working...
