Panasonic said Wednesday it’s aiming to improve lithium-ion battery energy density by 20 per cent in the next eight years, which is great news for the car companies it supplies, like Tesla and Toyota. The patents it’s filed give an insight into how it thinks it can do that, which is some complicated chemistry. According to a Reuters report, Panasonic Chief Technology Officer Shoichiro Watanabe said the 20 per cent gain would be found in building batteries that can run at a higher voltage. The company said that changing the additive mix in battery electrolytes and using single-crystal materials in the cathodes of batteries will make pushing the voltage higher possible.
