The?new?energy?vehicle?market?continues?to?be?hot,?and?the?power?battery?market?mainly?equipped?with?lithium?ternary?and?lithium?iron?phosphate?batteries?also?continues?to?expand.?With?the?rapid?growth?of?the?lithium-ion?battery?market,?the?limited?supply?of?raw?materials?will?also?become?an?important?factor?affecting?the?development?of?the?power?lithium?battery?market.

At?present,?ternary?lithium?batteries?are?widely?used?in?new?energy?vehicles?because?of?their?high?energy?density?and?strong?endurance.?However,?because?the?cobalt?contained?in?them?belongs?to?precious?metals,?the?cost?has?been?high?with?the?shortage?of?raw?materials.?In?addition,?from?the?perspective?of?lithium?resource?distribution,?lithium?resources?are?mainly?in?the?hands?of?Australia?and?Chile.?The?two?countries?together?control?75%?of?the?world's?lithium?resources.?More?than?85%?of?China's?lithium?resources?are?distributed?in?western?mountains?and?salt?lakes.?It?is?difficult?to?mine.?As?a?result,?80%?of?China's?lithium?resources?are?imported,?making?China?the?world's?first?importer?of?lithium?resources.

Sodium?is?a?rich?element?in?the?earth's?crust,?with?good?safety.?The?production?process?is?similar?to?that?of?lithium?batteries.?Under?the?background?of?the?rapid?development?of?power?batteries,?sodium?ion?batteries?have?set?off?a?boom?again.?Sodium?ion?battery?is?a?kind?of?rechargeable?battery,?which?mainly?depends?on?the?movement?of?sodium?ions?between?the?positive?and?negative?electrodes.?It?is?similar?to?lithium?ion?battery.

Working?principle?of?sodium?ion?battery:

The?research?on?sodium?ion?battery?was?first?started?around?the?1980s.?Electrode?materials?designed?and?developed?in?the?early?stage,?such?as?MoS2,?tis2?and?naxmo2,?have?poor?electrochemical?performance?and?slow?development.?In?recent?years,?with?the?development?of?the?new?energy?vehicle?market,?manufacturers?are?optimistic?about?the?prospects?of?sodium?ion?batteries,?and?have?laid?out?the?sodium?ion?battery?market?one?after?another.
