ISRO offers indigenously made lithium ion batteries technology to firms
Qualified companies or competent Indian industries/start-ups can now use its power storage technology to produce a range of Li ion cells for many purposes, mainly EVs or electric vehicles.
ISRO’s rocket sciences node Vikram Sarabhai Space Centre will transfer its in-house technology non-exclusively to each qualified production agency for a one-time fee of ₹1 crore.

About li-ion battery:

The Li ion cell production initiative is part of the government’s plan to achieve 100% EVs in the country by 2030.
Li ion battery is much in demand for use in handy consumer electronics goods too. Currently the batteries are imported mostly from China, South Korea and Taiwan.
NITI Aayog has also earlier called for setting up local production.

Advantages of LIBs:

A typical LIB is able to store 150 watt-hours electricity per kg of battery, compared to 100 watt-hours electricity in a nickel-metal hydride (NiMH) battery, and only 25 watt-hours electricity in a lead-acid battery.
LIBs hold a charge well. They usually lose approximately 5% of their charge each month, against a 20% monthly loss for NiMH batteries.
LIBs do not require complete discharge prior to recharging.
LIBs are able to handle more charge/discharge cycles.
Lithium-ion (Li-ion) batteries are less environmentally damaging than batteries containing heavy metals such as cadmium and mercury, but recycling them is still far preferable to incinerating them or sending them to landfill.

Disadvantages of LIBs:

LIBs start to degrade the moment they leave the factory. They usually last for only two to three years from the date of manufacture, regardless of whether used or unused.
LIBs are highly sensitive to higher temperatures. Higher temperature leads to a much faster degradation rate than normal.
If a LIB is fully discharged, it gets totally damaged.
LIBs are comparatively expensive.
There exists a small possibility that if the LIB pack fails, it may burst open into flame.
