San Jose, California. —
Electric cars are a game.
Change technology with fatal weaknessesthe battery.
The current battery is expensive and has a limited range, and it is difficult to drive a long distance without stopping charging.
Experts agree that consumers will never fully accept electric vehicles until they can travel to gasoline.

The battery is a complex system that converts stored chemical energy into electrical energy.
Progress often involves trade, researchers say.
The scope of improvement can lead to soaring costs or reduced battery life.

If you work hard for a progress, you usually fail on other things and you can\'t compromise on security.

Ion Chemistry in batteries
Sony commercialised lithium batteries for the first time in 1991.
Ion batteries are widely used in consumer electronics such as laptops and mobile phones, but are relatively new in cars.
The basic interior of the battery includes the anode with negative electricity, the cathode with positive electricity and the electrolyte.
When the battery is fully charged, the lithium ion is concentrated in the anode.
When the battery is discharged, the ion flows to the cathode, the current flows through the circuit, releasing energy.
The most popular anode material is graphite;
The cathode is usually made of lithium compounds, such as lithium iron phosphate.
Many startups are experimenting with battery chemistry and using a variety of materials for either an anode or a cathode or both.
While there is a saying in the industry that goes beyond lithium and uses new materials, many expect lithium-
Ion batteries will continue to dominate in the coming decades.
\"Everyone is moving fast on the technical curve,\" said Jim Dunley, vice president of Hardware Engineering at Tesla powertrain . \". “Lithium-
The ion is still in a strong orbit;
It has not peaked yet.
We are using better cells and we have learned how to pack them together more intensively.
But it\'s not just about making better batteries.
Better batteries mean we have better cars. ”McClatchy-
