Rechargeable lithium ion batteries power our phones and tablets they drive us from A to B in electric vehicles, and have many applications besides. Unfortunately, the devices that they power can fail and the batteries themselves are commonly only usable for two to three years. As such, there are millions batteries that must be recycled. Research published in the International Journal of Energy Technology and Policy describes a new way to extract the lithium and the cobalt that make up the bulk of the metal components of these batteries.

Researchers from RMIT University in Melbourne, Australia have demonstrated for the first time a working rechargeable "proton battery" that could re-wire how we power our homes, vehicles and devices.

Did you ever think about why your phone works at all? Probably not. But, if you think about it, all portable gadgets rely on a battery to keep ticking – and some have better battery life than others. That’s why we’re going to take a peek at what keeps your phone ticking and why some batteries do better than others.

Discharge and charge rate for lithium battery is the multiple between the current and the capacity, its unit is C. for example, if the lithium ion battery has a capacity of 800mAh, and its discharging current is 1600mA, then its discharge rate is 2 C rate, if its charging current is 800Ma, then its charging rate is 1 C, normal lithium ion battery and Li polymer battery can work with 1C charging and 2C discharging.

PCB or PCM is protection circuit board, usually for small battery, typical use is for digital batteries, like mobile phone battery,camera battery,mp3 player battery,GPS batteries,heated clothing batteries and so on. Most time, Its for 3.7V or 7.4V battery, It has four basic functions of over charging, over discharging, short circuit,over current.some batteries may also need PTC and NTC.

When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese scientists have offered a strategy to avoid plunging battery kinetics. In a study published in the journal Angewandte Chemie, they designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated.

There’s a lot of research going on around battery technology as devices as diverse as smartphones and cars are increasingly held back by limited energy storage. Naturally, we report on interesting advancements in batteries frequently. There are lithium-air batteries, aluminum-graphite batteries, and even bacterial batteries. Rarely do we have to dredge up one of those old posts to talk about the next step toward commercialization because there isn’t one.
