Spanish company Graphenano claims Graphene
Polymer batteries with triple the energy density of lithium ion and commercialization by end of 2016: "Graphenano is a Spanish company based in Yecla (Murcia) and they have presented their graphene polymer battery that can largely solve obstacles to the development of the electric car."

Very interesting, this will help promote electric cars, although power density is not mentioned and should be in the range of 1~3 kW/kg to be at least as competitive as Li-ion batteries (or exceeding 10 kW/kg to compare with supercapacitors and "bacitor" hybrids, especially if they're tackling commonplace devices/handhelds).

Tesla’s Maxwell Dry Battery and a Five Year Lead on the World:
"Tesla bought Maxwell Technologies for their dry battery technology. Maxwell proved 300 Wh/kg energy density is which 20-40% better than current Tesla batteries. Maxwell has a path with 15-25% improvement every 2-3 years. This should lead to 500 Wh/kg by 2027. This would give Tesla a 5 year battery lead on the rest of the world."

Technical breakthrough? Or is IBM just trying to make their stock go up?
IBM Reveals “Staggering” New Battery Tech, Withholds Technical Details: "IBM lifted the veil this week on a new battery for EVs, consumer devices, and electric grid storage that it says could be built from minerals and compounds found in seawater. (By contrast, many present-day batteries must source precious minerals like cobalt from dangerous and exploitative political regimes.) The battery is also touted as being non- flammable and able to recharge 80 percent of its capacity in five minutes. The battery’s specs are, says Donald Sadoway, MIT professor of materials chemistry, “staggering.” Some details are available in a Dec. 18 blog posted to IBM’s website. Yet, Sadoway adds, lacking any substantive data on the device, he has “no basis with which to be able to confirm or deny” the company’s claims."

Overblown battery claims are a dime a dozen. Obvious question would be what's the time to market. Many experts reckon we'll see solid state batteries in about 5 years (in actual shipping products), so even if this "breakthrough" is actual real and meaningful against today's technology, there's no guarantee it'll still be better by the time it ships. A common problem.
PS Seems to me that the main limitation on fast charging today is more like how much juice you can supply the car PPS All manufactures are already working to reduce cobalt, with Tesla reckoned to be well ahead of the pack (might be cobalt free soon, apparently) |

Long-lasting Lithium-Sulfur Battery Promises to Double EV Range:
"By designing a novel robust cathode structure, researchers have now made a lithium-sulfur battery that can be recharged several hundred times. The cells have an energy capacity four times that of lithium-ion, which typically holds 150 to 200 watt- hours per kilogram (Wh/kg). If translatable to commercial devices, it could mean a battery that powers a phone for five days without needing to recharge, or quadruples the range of electric cars. That’s unlikely to happen, since energy capacity drops when cells are strung together into battery packs. But the team still expects a “twofold increase at battery pack level when [the new battery is] introduced to the market,” says Mahdokht Shaibani, a mechanical and aerospace engineer at Australia’s Monash University who led the work published recently in the journal Science Advances."

Too good to be true?
Nano-diamond self-charging batteries could disrupt energy as we know it: "California company NDB says its nano-diamond 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 heart of each cell is a small piece of recycled nuclear waste. NDB uses graphite nuclear reactor parts that have absorbed radiation from nuclear fuel rods and have themselves become radioactive. Untreated, it's high-grade nuclear waste: dangerous, difficult and expensive to store, with a very long half-life. This graphite is rich in the carbon-14 radioisotope, which undergoes beta decay into nitrogen, releasing an anti-neutrino and a beta decay electron in the process. NDB takes this graphite, purifies it and uses it to create tiny carbon-14 diamonds. 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. To create a battery cell, several layers of this nano-diamond material are stacked up and stored with a tiny integrated circuit board and a small supercapacitor to collect, store and instantly distribute the charge. NDB says it'll conform to any shape or standard, including AA, AAA, 18650, 2170 or all manner of custom sizes. And so what you get is a tiny miniature power generator in the shape of a battery that never needs charging – and that NDB says will be cost-competitive with, and sometimes significantly less expensive than – current lithium batteries. That equation is helped along by the fact that some of the suppliers of the original nuclear waste will pay NDB to take it off their hands. Radiation levels from a cell, NDB tells us, will be less than the radiation levels produced by the human body itself, making it totally safe for use in a variety of applications. At the small scale, these could include things like pacemaker batteries and other electronic implants, where their long lifespan will save the wearer from replacement surgeries. They could also be placed directly onto circuit boards, delivering power for the lifespan of a device." See: https://newatlas.com/energy/nano-dia...-batteries-ndb |

Superlattices Could Make Bulky Capacitors Obsolete
"One roadblock to shrinking present-day electronics is the relatively large size of their capacitors. Now scientists have developed new “superlattices” that might help build capacitors as small as one-hundredth the size of conventional ones." See: https://spectrum.ieee.org/antiferroelectric |

Aluminum Sulfur—Is This How the Future Spells Lithium Ion?
"The nascent battery already has an energy density comparable to that of today’s lithium-ion batteries at cell level, and should come in at less than a sixth of the cost, the team reported in Natureon 24 August. The battery also charges in minutes and is nonflammable thanks to its molten salt electrolyte that does not burn. “You can put a blowtorch to this thing and it won’t catch fire,” says Sadoway."

Scientists discover lithium replacement that may revolutionize
EV batteries: '99.7% efficient after over 400 hours of use' "A team of scientists at the school’s Center for Materials Innovation found that crustaceans like crabs and lobsters contain a chemical in their shells called chitin, which can be used to power batteries when combined with zinc." "The University of Maryland’s study also found that chitin-zinc batteries were 99.7% efficient after over 400 hours of use, as reported by The Guardian, and that these batteries could likely be produced cheaply at scale."
