A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
In March 2013, Phinergy [5] released a video demonstration of an electric car using aluminium–air cells driven 330 km using a special cathode and potassium hydroxide. [6] On May 27, 2013, the Israeli channel 10 evening news broadcast showed a car with Phinergy battery in the back, claiming 2,000 kilometres (1,200 mi) range before replacement ...

The lead-acid battery is still used today in automobiles and other applications where weight is not a big factor. The basic principle has not changed since 1859. In the early 1930s, a gel electrolyte (instead of a liquid) produced by adding silica to a charged cell was used in the LT battery of portable vacuum-tube radios .
In practice, two components of the battery are made with lithium compounds: the cathode and the electrolyte. The electrolyte is a solution of lithium hexafluorophosphate, while the cathode uses one of several lithiated structures, the most popular of which are lithium cobalt oxide and lithium iron phosphate.

"Zaroori Tha" by Rahat Fateh Ali Khan is the most-viewed Pakistani video on YouTube. It is also the first Pakistani video to reach 1 billion views. On the American video-sharing website YouTube, "Tajdar-e-Haram" sung by Atif Aslam became first Pakistani music video to cross 100 million views.
Old 3 V zinc–carbon battery (around 1960), with cardboard casing housing two cells in series. By 1876, the wet Leclanché cell was made with a compressed block of manganese dioxide. In 1886, Carl Gassner patented a "dry" version by using a casing made of zinc sheet metal as the anode and a paste of plaster of Paris (and later, graphite powder).
The Al-Khalid/VT-1A (Urdu: الخالد ٹینک — Al-Xālid Ṫaiŋk, pronounced [əlˈxaːlɪd̪ ʈɛːŋk], lit. ' The Eternal Tank ') is a main battle tank family developed jointly by Norinco of China and Heavy Industries Taxila of Pakistan. The tank is based on the Type 90-II tank. [1] Around 310 Al-Khalid MBTs had been produced by 2014. [7]
