Replacing chemicals in li-ion battery with O2 enhances storage capacity 10x
In lithium-ion tech of today energy storage is limited by the lithium cobalt oxide electrode. These researchers have tried to replace it with a porous carbon electrode that lets lithium ions to react with oxygen drawn from the air during discharge. The replacement not only reduces the weight of the setup but allows a 10x increase in storage capacity.

Lead acid batteries can be recycled almost 100%
With recycling rates approaching 99%, lead-acid batteries are the most highly recycled product on the planet and substantially all of the materials recovered through recycling can be used to make new batteries. Neither NiMH nor Li-ion chemistries can even come close to matching the natural resource efficiency and environmental safety of lead-acid batteries. - Read More

Ni-Cd, Nickel Metal Hydride and Li-ion Batteries
The introduction of business tools like electronic calculators and the pagers, computers and telephones that quickly followed, drove the development of compact and light-weight rechargeable battery chemistries including nickel cadmium (Ni-Cd) nickel metal hydride (Ni-MH) and lithium ion (Li-ion). - Read More

Maintenance free valve regulated lead-acid (VRLA)
In the mid-70s, maintenance free valve regulated lead-acid (VRLA) batteries were introduced and rapidly became the dominant automotive technology. They worked so well in fact that most battery manufacturers cut their R&D budgets to the bone because VRLA batteries performed well and a complacent auto industry saw no reason to pay premium prices to fund further research. - Read More

Types of batteries until 1970
Until the 1970s, there were only two primary classes of batteries: rechargeable lead-acid batteries and disposable dry cells. Lead-acid batteries handled the heavy work like starting cars and providing emergency lighting while dry cells were used for flashlights, toys and consumer goods, including the first portable radios and tape players. - Read More

Battery recharging duration will be a major research area
As I keep saying, too many people are locked into a mindset that any EV must be recharged overnight, when that?s clearly not true. I expect quick recharge capability to be a major focus of battery research, nearly as much as reducing cost and extending the single-charge range.Never forget: The magic is in the second plug. - Read More
