Lithium ion battery


John Goodenough -- invented a new battery technology at the age of 94, which is powering your mobile devices. Goodenough is a German-born American professor and solid-state physicist at the University of Texas at Austin. He is widely credited for the identification and development of the Li-ion rechargeable battery rules for determining the sign of the magnetic super exchange in materials.

He and his team created a low-cost solid-state battery that can store at least three times the energy of modern lithium-ion batteries. It is noncombustible and has long life cycle which can be fully charged within minutes.

Goodenough said – “Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries”.

The new battery is solid-state, which has no liquid components in the battery. Traditional lithium-ion batteries are made of a solid cathode and anode separated by a liquid electrolyte that conducts electricity. Solid-state battery replaces that liquid with a more efficient glass compound.


Instead of a lithium-ion, a solid state battery will charge within minutes instead of hours, which would be very beneficial for people charging their phones and electric cars.

Electric cars run on electricity. Unlike conventional vehicles that use a gasoline or diesel-powered engine, electric cars use an electric motor powered by electricity from batteries or a fuel cell.  E cars are really a boon to our irritated environment because they avoid all the exhausted gas emissions that come from conventional diesel cars, thereby decreasing air pollutions. Main advantages E cars over conventional petrol/diesel cars:- ·        Lower running cost ·        Lower maintenance cost-less moving parts compared to diesel cars-Just maintain the breaks, tires and suspension ·        Best for environment-zero exhaust emissions! ·        Decreased air pollutions benefits health ·        Improved safety-studies says it has lower center of gravity which makes them less likely to roll over Importance of li-ion batteries in e-cars Lithium ion batteries are most common type of batteries found in electric cars. They have higher power to weight ratio,

How to prolong battey life of li-ion batteries The researches occurring in battery world is concentrating on lithium technologies and in that li-ion takes the top position. Li-ion batteries are not fully matured yet and lot of studies are going on behind, and is still improving. Lithium ion batteries are now powering satellites! It has become one of the best battery chemistry for power systems. Each battery systems has its own unique needs, such as Charging speed Discharge rate Tolerance in adverse temperatures Reasons for ageing of li-ion The battery performance is measured as its capacity, which is a health indicator. A li-ion battery may misbehave in its allotted time be due to heavy use or unfavorable temperature conditions. In the case of battery packs, they do not die suddenly, but the runtime gradually shortens as the capacity fades. The worst situations the li-ion battery can face is keeping it in high temperatures with full-charge. Do’s and Don’ts i

The  lithium-titanate-oxide (LTO) battery  is a type of  rechargeable battery  which has the advantage of being faster to charge [2]  than other  lithium-ion batteries , but the disadvantage of having a much lower energy density. LTO BATTERY has the characteristics of high energy, high magnification, high safety, wide temperature resistance, long cycle life, etc., which can cover all energy storage applications. It is widely used in new energy vehicles and industrial & commercial parks, communication base stations, grid frequency modulation, rail transit, and yacht, electric boat, Family housing, military scientific research and other energy storage fields, have broad market prospects and application value. Special Features for Yinlong LTO battery Low Maintenance.. No Emissions, Highly customisable electric vehicles of all sizes and shapes to suit all transportation requirements from urban and intercity commuting to delivery vans. Ø   High Safety ： No smoke, no fire, no exp
