As of May 16, 2012, USPS has changed part of their mailing rules and standards. Lithium batteries and cells (both rechargeable and non-rechargeable) are now not allowed to be shipped internationally or to any APO, FPO, and DPO locations. This means that mailers also cannot send out products that have lithium batteries inside of them, including tech gadgets such as cell phones, MP3 players, laptops, and digital camera.
After January 1, 2013, limited quantities may be allowed to ship out internationally, as long as "the batteries are properly installed in the personal electronic devices they are intended to operate."
This does not affect the current rules for mailing lithium products within the United States, and lithium batteries (and their corresponding technical products) may still be shipped out normally. However, for international shipping, mailers may have to resort to private carriers such as FedEx.

Today, the car makers BMW and Toyota have decided to pool their forces together in an effort to research the next-generation of Lithium-Ion batteries and battery cells. More specifically, they'll be focusing on "increasing the performance and capacity of lithium-ion battery cells".
This isn't the first time they've made headlines together, however: back in Dec. 2011, the two companies signed a memorandum of understanding (MOU) concerning a "mid-to-long-term collaboration on next-generation environment-friendly technologies", so today's news really shouldn't be a shocker.
Originally, the vehicle-giants were to focus on the application of lithium-ion battery cells towards hybrid and electric cars. However, this doesn't necessarily mean that our smartphone or laptop batteries won't get a nice boost in research as well.

A recent groundbreaking study has led to success in increasing charging capacity and speed of lithium ion batteries. Professor Harold Kung and his group of engineers at Northwestern University have accomplished this feat by adjusting graphene layers, which are directly related to how fast charging can occur. Now, charging capcity and speed increase by a factor of ten, just by poking small holes in the battery's graphene layers.
Additionally, Kung's team also increased the density of lithium ions, which allowed for their test-batteries to last for over a week on a single charge. (The science behind it isn't so simple, of course.) The downside is that these lithium-ion batteries lost their fast-charging long-lasting abilities after roughly 150 charges, which is a drastic difference in how long lithium-ion batteries normally last.
If perfected, this science could help create the next generation lithium-ion battery. Check out the source link below for more info.
