Q & A

What is the current status of lithium-ion batteries in electric cars?

Lithium-ion batteries are not yet perfected, but they are the dominant technology in electric cars, powering devices like phones, tablets, laptops, and electric vehicles like Tesla cars.

Why are solid-state batteries considered an exciting alternative to lithium-ion batteries?

Solid-state batteries offer greater energy density, potentially allowing electric cars to have two or three times the current range, or a smaller, lighter, and less expensive battery that charges faster.

What are the general estimates for charging time with solid-state batteries?

Solid-state batteries are estimated to allow an 80% charge in 15 minutes, which is faster than current lithium-ion batteries.

How do solid-state batteries address the issue of battery life?

Solid-state batteries are expected to have longer life, with General Motors hoping to produce a million-mile life battery, reducing concerns about battery recycling.

What is 'thermal runaway' and how do solid-state batteries mitigate this risk?

Thermal runaway is a condition where lithium-ion batteries can get too hot and burn or almost explode. Solid-state batteries have less risk of thermal runaway.

What are the main challenges that solid-state batteries currently face?

Solid-state batteries face challenges such as expansion and contraction leading to micro cracks, the growth of dendrites that can cause battery failure, and high production costs.

Which company has a significant partnership with Volkswagen to develop solid-state batteries?

QuantumScape is partnered with Volkswagen and aims to produce a solid-state battery for use in some Volkswagen EVs as early as 2024.

What is Toyota's plan regarding solid-state battery implementation?

Toyota plans to have a limited production car powered by solid-state batteries on the market by 2025, and their partner Panasonic is heavily invested in traditional lithium-ion batteries.

How does Bollore's approach to solid-state batteries differ from other companies?

Bollore has a solid-state battery on the market for use in buses, and they plan to have a passenger car version available around 2026.

What is Solid Power's unique approach to solid-state battery development?

Solid Power focuses on the manufacturing process of solid-state batteries, aiming to create a design that can be produced on existing lithium-ion production lines to support scaling.

What recent breakthrough has Samsung achieved in solid-state battery technology?

Samsung has reportedly solved the dendrite issue and developed a battery design that can be discharged and recharged up to a thousand times, potentially leading to a 350,000-mile battery life.
