The scientists at John Hopkins Applied Physics Laboratory, US, have developed Lithium-Ion batteries that can operate under extreme conditions like submersion, ballistic impact, cutting and heat. In simple lay man terms, they can operate even under fire!
The Lithium-Ion batteries that are commonly used in every household item starting from smartphones are susceptible to catastrophic fire and explosion. Because of this, many phones were banned from airlines and ships. The US Navy had prohibited the use of e-cigarettes on ships and submarines because of the danger the batteries possessed.
The Technology behind the battery
The scientists have used water-in-salt and water-in-bisalt electrolytes in the batteries. These electrolytes were incorporated in a polymer matrix to reduce water activity and elevate energy capabilities of the battery. This gives the batteries higher energies to withstand heat and pressure.

India and Bolivia have signed an agreement for the development and industrial use of lithium, a prime component used to power electric vehicles and cell phones during the state visit of the President Ram Nath Kovind to Bolivia.
- India and Bolivia agreed to forge a mutually beneficial partnership to facilitate Bolivian supplies of lithium Carbonate to India and foster joint ventures for lithium battery/cell production plants in India. This agreement will make Bolivia, which is known to have one-fourth of the world’s lithium reserves, one of the major provider of metal for India’s e-mobility and e-storage needs.
- The agreement facilitates mechanisms for the commercialization of Lithium Carbonate and Potassium Chloride produced in Bolivia by Yacimientos de Litio Bolivianos Corporación (YLB – Corporación).
Why the agreement can be a game changer?
- Bolivia is estimated to hold over 60 per cent of the world’s reserves for lithium, which is required for lithium-ion batteries for portable electronics, and electric vehicles, but has not yet started producing it commercially.
- India is the second largest manufacturer of mobile phones in the world and has the ambitious goal of 30 per cent electric vehicles by 2030. But India imports all its lithium-ion batteries since India has no known sources of lithium, and zero lithium-ion battery manufacturing capabilities currently.
- As a result, India is heavily dependent on China, Taiwan and Japan for import, especially of batteries required for portable electronics.
- With the MoU number of Indian companies setting up production capabilities in Bolivia goes up, as well as the import of lithium to India. Domestic production is also set to see a boost, from the automotive perspective. Further, the arrival of hybrids and electric vehicles from as early as 2020 onwards, will force manufacturers to look at local production.
This agreement could turn out to be the backbone for the recently launched FAME India policy (Faster Adoption and Manufacture of (Hybrid and) Electric Vehicles) and will also give a substantial push to India’s ambition to have at least 30 per cent of its vehicles run on electric batteries by 2030.
