No battery problem in future?

A California company name "NDB" is started new technology by nano-diomand batteries will absolutely upend the energy equation, acting like tiny nuclear generators. They will blow any energy density comparison out of the water, lasting anywhere from a decade to 28,000 years without ever needing a charge. They will offer higher power density than lithium-ion. They will be nigh-on indestructible and totally safe in an electric car crash. And in some applications, like electric cars, they stand to be considerably cheaper than current lithium-ion packs despite their huge advantages.

The diamond structure acts as a semiconductor and heat sink, collecting the charge and transporting it out. Completely encasing the radioactive carbon-14 diamond is a layer of cheap, non-radioactive, lab-created carbon-12 diamond, which contains the energetic particles, prevents radiation leaks and acts as a super-hard protective and tamper-proof layer

Here we can use this battery long lasting with 28,000years in single charge so of you once charge it will never down even you died also 

There is many uses with the charger devices in present generation .

But now it is most costly product and most expensive but as going it will become less price. 

Mention that it is starting stage technology we have to wait long time for this battery. 

Hope this helps many problems for battery using devices
